A Home Worth the Wait

Buying a home is rarely just a transaction. For many of our clients, it marks one of life’s true milestones the moment they stop searching and start building a life around four walls that finally feel like theirs.

Some people find that home right away. Others, like me, find it in pieces, over years, one project at a time.

When I first purchased my own home in Fair Oaks, California, it was a true fixer-upper. Nothing about it looked like the home I imagined I would eventually raise a family in, but I could see its potential. Over the years, we have remodeled almost every corner of it. It has been a labor of love, a genuinely long process, and I would not trade a single phase of it.

Some people would say it might have been smarter to sell and buy something newer once we started upgrading. I understand that argument, but for us, there was real joy in the creative process of shaping a house into the home we had always pictured.

The biggest project we ever took on was our master suite addition, a space we lovingly call The Sanctuary. We opened it to the outdoors with large glass doors, added an indoor-outdoor shower, and built a private deck that looks out over our family of redwoods. It really does feel like a sanctuary. Financing it mattered just as much as designing it: we used a home equity line of credit for most of the addition, and paid for the rest with savings, the same combination of tools we help clients think through every day.

If a twenty-year remodel is not exactly your idea of a good time, you may be somewhere else entirely in the process, still dreaming about what your next home should be. Getting to the point in life where you can buy your forever home is its own kind of process, both financially and emotionally. Some people know instantly that they want the mountains, the water, or the quiet of the country. Others are drawn to the suburbs, a bigger lot, and the amenities that make everyday life easier. Figuring out what feels right for your family takes time, and that is completely normal.

I currently have three sets of clients who are still shopping for their dream home. One couple has been searching for four years, another for three years, and a third for a year and a half. Patience is absolutely part of the process. So is having a team who can walk that journey with you. I always say that having the right team in place, a mortgage advisor who understands your full financial picture and a premier realtor who knows the market inside and out, can make the difference between a search that drifts and a search that leads somewhere real.

If you’re still defining what your forever home looks like, How to Buy Your Dream Home in California walks through every stage of the journey, from creating your vision and evaluating your current home to choosing the financing strategy that supports your next chapter.

Whether your forever home is already waiting behind your own front door, the way mine was, or still out there somewhere you haven’t found it yet, the financing conversation looks a lot alike, especially once the price point crosses into jumbo territory, which is where the rest of this guide picks up.

If you’re still defining what your forever home looks like, our Homebuyer Resources include planners, checklists, and calculators to help you build your strategy before you begin shopping.

What is a Jumbo Home Loan?

A jumbo loan is a mortgage whose original loan amount is above the conforming limit for the property’s county and number of units. Because Fannie Mae and Freddie Mac generally cannot acquire loans above those limits, jumbo loans are offered under an individual bank, credit union, or mortgage investor’s guidelines.

That difference matters. Jumbo underwriting is not governed by one universal matrix. Minimum down payment, credit score, debt-to-income ratio, reserves, property eligibility, and loan size can vary meaningfully from one investor to another.

Conforming, High Balance, and Jumbo

How to qualify for a Jumbo Loan

Jumbo underwriting asks a straightforward question: does the entire financial picture support a mortgage of this size? The answer is built from several connected factors rather than one magic number, much like a remodel is really a series of decisions that only make sense together.

1. Down payment and loan-to-value

Some full-documentation jumbo programs begin around 10% down for a qualified primary-residence buyer. Many purchases fall in the 15% to 25% range, while larger loan amounts, second homes, investment properties, condos, or unusual properties may require 20% to 30% or more. A larger down payment can also improve pricing and expand the number of eligible programs.

The smallest down payment is not automatically the smartest down payment. A buyer may intentionally keep funds available for two-home carrying costs, renovations, taxes, furnishings, investments, or a planned principal reduction after another property sells. It’s a version of the same trade-off we made with The Sanctuary: how much cash do you put in today, and how much do you keep on hand for the life still happening around the project.

2. Credit score and credit history

Most jumbo loan products require a minimum credit score somewhere in the 660 to 680 range, and some programs, particularly for higher leverage or larger loan amounts, require an even higher minimum of 700. A few select portfolio programs may consider scores modestly below that range with stronger equity and case-by-case review, but as a category, jumbo financing is simply not built for credit-challenged borrowers. The lender also reviews the depth and pattern of the credit history, not only the score on the day of application.

• Pay revolving balances on time and avoid opening new accounts during the mortgage process.
• Do not move large sums between accounts without keeping a clean paper trail.
• Review credit early enough to correct errors and plan balance reductions strategically.
• A past credit event may not be an automatic denial, but seasoning and program rules matter.

3. Debt-to-income ratio

Debt-to-income ratio, or DTI, compares required monthly obligations with gross qualifying monthly income. The housing payment generally includes principal and interest, property taxes, homeowners insurance, association dues, and any required mortgage insurance. Other obligations can include car loans, student loans, credit-card minimums, alimony or support, and payments on other real estate.

There is no universal jumbo maximum. Depending on the investor and the strength of the file, common maximums may be 43%, 45%, or as high as 49.99%. Approval near the upper end typically requires strong compensating factors and does not mean that payment is comfortable for every household.

A portfolio program may use its own rules. The Portfolio ARM, for example, permits a maximum 43% front- or back-end DTI without its higher-DTI condition, or up to 50% when monthly income is at least $10,000, subject to a pricing adjustment and full underwriting review.

4. Cash reserves after closing

Reserves are simply the eligible savings and liquid assets you have left over after your down payment and closing costs are paid. Think of them as your financial cushion, proof to the lender that you could keep making your mortgage payment for a period of time even if something disrupted your income. Reserves are measured in months of your total housing payment, and depending on the loan program, a jumbo lender may require 3 months, 6 months, or 12 months of reserves. Larger loan balances, multiple financed properties, higher DTI, second homes, investment properties, or more complex income can sometimes push that requirement higher, occasionally to 18 or 24 months.

The underwriting guide uses a particularly clear formula: six months of PITI for every property owned, including the subject property, and at least three months of the subject property’s required reserves must be liquid, non-retirement funds. It generally values retirement funds at 75% for borrowers younger than age 59½ and treats them as non-liquid. These are program-specific rules, but they illustrate why owning multiple homes can materially increase the reserve requirement.

• Checking and savings accounts may count at their documented value.
• Stocks, bonds, and investment accounts may be discounted for market volatility.
• Vested retirement assets may be eligible under program-specific access and valuation rules.
• Business funds, trust assets, restricted stock, cryptocurrency, and borrowed funds require special review and may not count.
• Assets used for closing generally cannot also be counted as reserves.

5. Full documentation of income and assets

Traditional jumbo financing is a full-documentation loan. The underwriter must be able to verify that qualifying income is stable, likely to continue, and calculated under the program’s rules. High earnings alone do not solve inconsistent or undocumented income.

6. The property and appraisal

The home is part of the underwriting decision. Luxury and unique properties may have fewer comparable sales, which can make the appraisal more complex. Some jumbo programs require a second appraisal or an appraisal review above certain loan sizes. Condominiums, acreage, mixed-use characteristics, accessory units, deferred maintenance, and nonstandard construction may also affect eligibility.

7. Compensating factors

A strong jumbo file often has several strengths working together: excellent credit, meaningful liquid reserves, a conservative loan-to-value ratio, stable income, limited payment shock, and clean documentation. A higher DTI or smaller down payment may be acceptable in one program only when the rest of the file is especially strong.

How a relocating family used High Balance financing to preserve cash

A family moving from Texas found a $1,295,000 home in Concord with an acre, a swimming pool, an open layout, and room for two beloved Mastiffs. They wanted to buy before selling their Texas home, so liquidity mattered.

With 10% down, the proposed loan amount was approximately $1,165,500. For a one-unit property in Contra Costa County, that amount was below the 2026 high-cost conforming ceiling of $1,249,125. Instead of assuming the loan had to be jumbo, the team compared a High Balance conforming option with a 10%-down jumbo option.

At that time, the High Balance structure offered the more attractive overall fit. The borrowers also chose a rate approximately 0.25 percentage point above a zero-discount-point option in exchange for roughly $14,000 in lender credits toward eligible closing costs. That reduced the cash needed before their Texas home sold.

Their longer-term plan was to sell the prior home, apply proceeds to the California mortgage, and evaluate a refinance if future rates and costs made sense. A future refinance was a plan, not a guarantee; the original payment still had to be affordable on its own.

If refinancing becomes part of your long-term strategy, our Smart Homeowner’s Guide to Refinancing explains the options available and how to determine whether refinancing makes financial sense.

Mortgage points and lender credits

Points and lender credits are two sides of the same pricing tradeoff. They change how much you pay at closing and how much you pay over time.

How points are calculated

One point equals 1% of the loan amount. On a $1,000,000 mortgage, one point is $10,000; 0.50 point is $5,000; and 0.25 point is $2,500. One point does not equal a guaranteed 0.25% rate reduction. The rate improvement associated with a point changes with the lender, product, and market.

Use a break-even analysis

Divide the additional upfront cost by the monthly payment savings to estimate the number of months needed to recover the points. Then compare that period with how long you realistically expect to keep the loan. Include refinance costs, not just the hope that rates will fall.

30-year fixed vs. 5/1 ARM vs. interest-only

These structures solve different problems. The right comparison looks beyond the first payment and asks what can change, when it can change, and what you will do if your preferred future event never occurs.

30-year fixed-rate jumbo

A fixed-rate loan provides the clearest payment path. The principal-and-interest payment does not change because market rates rise. Property taxes, insurance, association dues, and escrow amounts can still change.

Pros

• Long-term payment stability.
• No future interest-rate reset.
• Straightforward budgeting and comparison.
• Principal is paid down with every scheduled payment.

Cons

• The initial rate may be higher than an ARM offer.
• The payment is higher than an interest-only payment at the same rate and balance.
• If you sell or refinance soon, upfront points may not reach break-even.

5/1 adjustable-rate jumbo

A 5/1 ARM generally has an initial rate fixed for five years and adjusts once per year afterward. Some modern products adjust every six months, so verify the exact note. After the fixed period, the rate is calculated using a published index plus a fixed margin, subject to initial, periodic, and lifetime caps.

Not all ARMs are created equal

Several ARM structures exist in the market, including 3/1, 5/1, 7/1, and 10/1 options, but not all of them currently offer a meaningfully lower rate than a 30-year fixed loan. Right now, the 5/1 Jumbo ARM and the 5/1 VA ARM are the only ARM products that consistently show a reduced rate significant enough to lower your monthly payment. Other ARM variations generally do not offer better pricing, largely because of the shape of the bond yield curve and because most investors simply don’t have the appetite to buy those other ARM structures at an attractive rate. This is real, on-the-street data, not a theoretical rule, so if an ARM is part of your strategy, the 5/1 structure is typically where the actual savings live.

Pros

• Potentially lower initial rate and payment.
• Can reduce interest cost during a known short holding period.
• May fit a buyer expecting a documented liquidity event, relocation, or sale within five years.

Cons and preparation

• The rate may rise after the fixed period.
• A planned refinance depends on future rates, equity, credit, income, and property eligibility.
• You should qualify emotionally and financially for the maximum payment allowed by the caps, not only the introductory payment.
• Request the index, margin, adjustment dates, and all caps in writing before choosing the loan.

Portfolio ARM program spotlight

One example of why it pays to compare investors is the Advancial Federal Credit Union Portfolio ARM. The November 2025 program guide describes a 30-year principal-and-interest mortgage available as a 3/1, 5/1, or 7/1 ARM, with loan amounts up to $5 million. Investment-property loans amortize over 30 years but carry a 15-year balloon, which creates a separate maturity deadline borrowers must plan for.

For a primary one-unit residence, the published matrix allows up to 80% LTV on loans through $2.5 million, with a 740 minimum score at $2.5 million for that leverage; permitted LTV then steps down as the loan amount rises. A separate case-by-case structure permits combined loan-to-value above 80% and up to 90% for a primary single-family residence using an outside subordinate lien, with a $2 million combined-loan cap. Exact pricing, qualification, and availability must be confirmed when the borrower applies.

The same guide can consider several profiles that may not fit a standard jumbo box, including non-warrantable condos, condotels, co-ops, acreage and hobby farms, mixed-use residential property, work-visa borrowers, foreign nationals, asset depletion, selected one-year self-employed documentation, LLC vesting for investment property, and delayed financing. Each has separate LTV, documentation, reserve, and property-review rules.

Interest-only jumbo: flexibility with a deadline

In the structure discussed in this guide, the required payment covers interest only for the first 10 years. You may be allowed to make voluntary principal payments, but the scheduled payment does not reduce the balance. At the end of year 10, the remaining balance must be amortized over the final 20 years. If the interest rate is adjustable, the rate may also change under the note.

Qualifying for an interest-only jumbo loan works differently than qualifying for the payment you will actually make in year one. Lenders do not let you qualify using the lower, interest-only payment. Instead, you have to income-qualify based on the note rate amortized over the remaining 20 years, as if it were already a full principal-and-interest payment. Because of that, your income needs to be meaningfully higher than your other debts and your total housing payment, principal, interest, taxes, and insurance combined, often shorthanded as PITI. Interest-only can absolutely lower your monthly cash outlay, but it does not lower the income required to qualify for the loan.

A simple payment-shock example

Assume a $1,500,000 balance at 7.00% solely for illustration. The interest-only payment is $8,750 per month. If the balance is still $1,500,000 after 10 years and the rate remains 7.00%, amortizing that balance over the remaining 20 years would require principal and interest of approximately $11,630 per month — about $2,880 more. Taxes, insurance, and association dues are not included, and an adjustable rate could produce a different payment.

Prepare before you choose IO

• Stress-test the year-11 payment using the current rate, a higher rate, and the maximum rate permitted by the note.
• Decide whether you will make voluntary principal payments and automate them if they are part of the plan.
• Keep a dedicated liquidity reserve; do not count on appreciation or a refinance.
• Identify the expected exit: sale, refinance, principal reduction, or conversion to the amortizing payment.
• Review the plan annually and again at least 24 months before the IO period ends.

The Danville move-up buyers who took time to find the right community

Past clients first began discussing a move in 2022. New to the Bay Area, they wanted more space and a neighborhood that felt like a long-term fit. After years of exploring, they focused on Danville and found a $2.6 million home with views, a large yard, a pool, indoor-outdoor living, Tigerwood floors, and an open kitchen.

They planned to buy before selling their Alameda home and qualify while temporarily carrying both housing payments. That made documentation, reserves, and the treatment of the departing residence central to the preapproval.

The comparison included a VA jumbo ARM for an eligible veteran, a 30-year fixed jumbo loan with approximately 25% down, and a 30-year jumbo product with a 10-year interest-only period. The ARM offered an attractive initial rate at the time, while the fixed loan provided certainty and the IO structure offered the lowest required initial payment.

The property also had to fit the financing. A VA-backed offer can involve appraisal and Minimum Property Requirements, and a wood-destroying insect inspection or clearance may apply. Inspection, repair, and payment terms should be reviewed for the property and current VA rules rather than assumed.

It’s exactly this kind of years-long search, patiently narrowing down what mattered most, that reminds me why I always tell clients not to rush the process. The right home is worth waiting for, and the right financing plan should be ready the moment it appears.

Buying before selling your current home

Move-up buyers often want to avoid temporary housing and two moves. Buying first can make that possible, but the new loan must be structured around the period when both properties are owned.

Many move-up buyers assume they have to sell their current home first, but there are financing strategies that may allow you to purchase before selling, depending on your situation.

What the lender evaluates

• Whether both housing payments must be included in DTI.
• Whether a fully executed sales contract allows the departing payment to be excluded under the selected program.
• The source of the down payment and whether a bridge loan, home-equity line, securities-backed line, gift, or asset sale is permitted.
• Reserves remaining after both the purchase and any payoff or transfer.
• How rental income may be treated if the current home will become a rental.
• Whether the plan depends on a recast or refinance after the prior home sells.

If you’re wondering whether short-term financing is the right solution, The Ultimate Guide to a Bridge Loan explains how bridge loans work, who they may benefit, and how they can help you purchase your next home before selling your current one.

Recast vs. Refinance

A recast applies a large principal payment and recalculates the payment over the remaining term without replacing the loan; not every loan or investor permits it. A refinance creates a new loan and requires new qualification, appraisal, pricing, and closing costs. Ask about recast eligibility before closing if it is part of the plan.

Construction-to-permanent financing

When the ideal home does not exist, a construction-to-permanent loan can finance the lot and construction, then convert to permanent financing after completion. The lender approves the borrower, builder, plans, specifications, budget, timeline, appraisal, and draw process.

For some buyers, the right home isn’t available because it hasn’t been built yet. How do I build a custom home explains the process from purchasing land through construction financing.

How the construction phase works

• The project is appraised using plans, specifications, site, and comparable properties to estimate the as-completed value.
• The lender establishes the approved loan amount under its loan-to-cost and loan-to-value rules.
• Funds are released in draws after inspections confirm completed work.
• During construction, the borrower typically pays interest only on funds actually advanced, so the payment grows as draws accumulate.
• At completion, the loan converts or modifies into its permanent phase under the agreed product terms.

Costs buyers should plan beyond the contract

• Architectural, engineering, permit, utility, site-work, and design costs.
• Builder contingency and owner-requested change orders.
• Interest, taxes, insurance, and current-home carrying costs during construction.
• Potential delays, extension fees, and interest-rate lock or conversion terms.
• Landscaping, window coverings, furnishings, and items excluded from the builder contract.

When the dream home was not on the market, they decided to build it

A Folsom family had searched since 2023 for a contemporary home in Serrano, El Dorado Hills: clean architectural lines, expansive glass, bright finishes, an open entertaining plan, and seamless indoor-outdoor living. After nearly three years, they found a builder and a homesite instead.

The lot was $595,000 and the projected construction budget was $2,200,000, for a total stated project cost of $2,795,000 before closing costs, reserves, and contingency. The estimated as-completed value was $3,000,000.

At 65% of the estimated as-completed value, the illustrated construction loan was $1,950,000. The difference between the stated project cost and loan amount was approximately $845,000. The actual required contribution could be higher after lender cost tests, closing costs, prepaid items, contingency, and nonfinanceable expenses.

They owned their Folsom home free and clear and planned to remain there during the roughly eight-month build, then sell after moving. During construction, the interest-only payment would be based on disbursed funds. The low-7% planning rate discussed at the time was a scenario, not a current quote or guaranteed permanent rate.

VA jumbo considerations

“VA jumbo” is an industry term for a VA-guaranteed loan that is large enough to be considered jumbo in the conventional market. VA rules and lender overlays both matter.

• With full entitlement, VA does not impose a county loan limit, but the lender still determines affordability, credit eligibility, maximum loan size, and property acceptability.
• With remaining rather than full entitlement, the county conforming limit can affect how much may be borrowed without a down payment. A down payment may be required to achieve the guaranty expected by the lender or secondary market.
• VA itself does not set a universal minimum credit score, but lenders may.
• The home must satisfy VA appraisal and Minimum Property Requirements. Inspections or repairs may affect timing and offer strategy.
• The VA funding fee generally applies unless the borrower qualifies for an exemption. Veterans receiving or eligible to receive compensation for a service-connected disability may be exempt under VA rules.
• Entitlement can often be restored and reused after the prior VA loan is paid and the property is sold, and some borrowers may also have remaining entitlement. Confirm the Certificate of Eligibility early.

REAL CLIENT STRATEGY

A veteran’s homeownership strategy across five moves

One client followed career opportunities from Elk Grove to the Bay Area, then Seattle, Austin, and back to California. Different moves called for different financing strategies.

In Austin, he purchased a $1,136,000 home with 100% VA financing. After selling and returning to California, he bought a $1.1 million property on two acres in Concord using a conventional loan with 10% down.

He invested approximately $250,000 in a substantial renovation. Six months after purchase, the property appraised at $1.6 million — an indicated increase of roughly $500,000 from the purchase price, although renovation cost, market movement, transaction costs, and future sale price all matter when evaluating investment return.

The original conventional rate was 6.99%. After the renovation, he refinanced into a 30-year fixed VA loan at 5.75% under the market and qualification conditions then available. Because he was exempt from the VA funding fee due to qualifying service-connected disability status, the refinance avoided that charge.

The Doctor Loan: built for physicians and select professions

Not every high-value purchase fits neatly into traditional jumbo underwriting. For physicians and a handful of other qualifying professions, we offer a dedicated Doctor Loan program at Amy DeBusk Home Loans.

This program allows up to 100% financing, with no down payment required, on loan amounts up to $1,500,000, and it carries no private mortgage insurance regardless of loan-to-value. The minimum credit score requirement is 680.

Eligibility generally extends to physicians (MD or DO) at various stages of their careers, along with several other qualifying professions. The specific list of eligible professions and career-stage requirements varies by program, so for a full breakdown of who qualifies and how the program works, see our companion Doctor Loan Guide.

Your jumbo preapproval roadmap

• Define the life plan: Decide where you want to live, how long you expect to stay, and whether you must buy before selling.
• Set a comfort payment: Include taxes, insurance, HOA dues, maintenance, and a buffer — not only principal and interest.
• Map the funds: Separate down payment, closing costs, reserves, renovation or construction funds, and post-closing liquidity.
• Collect full documentation: Provide complete income, asset, property, business, and housing documents early.
• Compare programs: Review High Balance, jumbo fixed, ARM, interest-only, VA, Doctor Loan, and construction options when relevant.
• Stress-test the future: Model ARM resets, IO amortization, two-home carrying costs, and delays in a sale or build.
• Underwrite before the offer: When possible, obtain a fully reviewed preapproval rather than relying on a quick calculator.
• Update before every offer: Rates, assets, credit, property details, and county limits can change the result.
