Jumbo Loans in Northern Virginia: Down Payments, Reserves and Rates

Jumbo loans in Northern Virginia are mortgages above the conforming limit set each year by FHFA, and they are common for homes priced well above $1 million in Arlington, McLean, Great Falls, Alexandria and parts of Loudoun. Because Fannie Mae and Freddie Mac don’t buy them, each lender sets its own requirements, typically a down payment of 10% to 20% or more, strong credit, a debt-to-income ratio in the low 40s or below, and six to twelve months or more of payments in reserve. Rates vary by lender and can sit above or below conforming rates, so shop carefully.

Conforming, high-balance or jumbo?

Every November, the Federal Housing Finance Agency announces conforming loan limits for the following year. For 2026, FHFA set the one-unit baseline at $832,750, up $26,250 from 2025, and the ceiling for high-cost areas at $1,249,125 (150% of the baseline). Northern Virginia jurisdictions are high-cost areas, so their limits sit above the baseline. My post on 2026 loan types and loan limits walks through how the limits apply locally.

Loan type	Size (one-unit, 2026)	Who sets the rules	Typical traits
Conforming (baseline)	Up to $832,750	Fannie Mae and Freddie Mac guidelines	Widest availability, PMI below 20% down
High-balance conforming	Above $832,750 up to your county’s limit (no higher than $1,249,125)	Fannie Mae and Freddie Mac, with some added restrictions	Rates and terms similar to conforming, sometimes slightly higher
Jumbo (non-conforming)	Above your county’s limit	Each lender or investor	Larger down payments, reserves and stricter documentation

The practical takeaway: a loan of $1 million in Northern Virginia may still be conforming, while a loan of $1.3 million will not. Ask your lender to confirm your county’s exact limit before you set a price range.

Down payments

There is no single jumbo down payment rule. Common patterns include:

• 20% down is the most widely available and usually prices best.
• 10% to 15% down jumbo programs exist at many lenders, sometimes with mortgage insurance or a slightly higher rate.
• Larger loan amounts often require more down. Some lenders step up requirements for loans above $1.5 million or $2 million.
• Piggyback structures pair a first mortgage at the conforming limit with a second mortgage or home equity line, which can be cheaper in some markets. Compare total cost, not just the first lien rate.

Gift funds may be allowed but often with stricter rules than conventional loans, so tell your lender early if family help is part of the plan.

Reserves, credit and debt-to-income

Requirement	What lenders commonly look for (varies by lender)
Credit score	Often 700 or higher; the best pricing usually goes to 740 and up
Debt-to-income ratio	Often 43% or lower; some allow higher with compensating factors
Cash reserves	Frequently 6 to 12 months of the full housing payment, sometimes more for larger loans or multiple properties
Appraisal	One full appraisal; some lenders require a second appraisal above a set loan size
Income documentation	Two years of tax returns or W-2s, recent pay stubs, and for business owners, business returns

Reserves are the requirement that surprises buyers most. Retirement accounts and brokerage balances may count, often at a discount. Get the lender’s reserve calculation in writing. Our explainer on debt-to-income ratio shows how lenders run the math.

Rates and how to shop

Jumbo rates move with the broader market, but the gap between jumbo and conforming rates changes over time. In some periods jumbo rates have been lower than conforming rates, in others higher. Banks that keep jumbo loans on their own books may offer relationship pricing if you move assets to them.

1. Get at least three Loan Estimates on the same day for the same loan amount and lock period.
2. Compare the rate, points, lender fees and any relationship requirements side by side. The CFPB has guides to reading a Loan Estimate.
3. Ask about adjustable-rate options. Many jumbo borrowers use 7-year or 10-year ARMs; understand the caps and the reset before choosing one.
4. Check how long underwriting takes. Jumbo files can take longer, which matters in a competitive offer.
5. Read how to choose a mortgage lender for questions to ask.

A worked example

Illustrative numbers only; the rate below is a hypothetical, not a quote or a current market rate.

• Purchase price: $1,600,000 for a single-family home.
• Down payment: 20%, or $320,000. Loan amount: $1,280,000, which is above the 2026 high-cost ceiling, so it is a jumbo loan anywhere in Northern Virginia.
• Hypothetical rate: 6.5% on a 30-year fixed. Principal and interest: about $8,090 a month.
• Illustrative taxes and insurance: about $1,700 a month, for a total housing payment of roughly $9,790.
• Reserves at 12 months: about $117,500 in addition to the down payment and closing costs.
• Income needed at a 43% debt-to-income ratio with no other debts: roughly $22,800 a month, or about $273,000 a year.

Now compare an alternative. If a bigger down payment brought the loan within your county’s conforming limit, you could gain access to conforming guidelines. Run both scenarios through the mortgage calculator and ask your lender whether the extra cash at closing is worth it.

Common mistakes

• Assuming any loan over $1 million is jumbo without checking the county limit.
• Forgetting that reserves are on top of the down payment and closing costs.
• Moving large sums between accounts during underwriting without a paper trail.
• Comparing only rates and ignoring points, fees and relationship requirements.
• Choosing an ARM without planning for the reset.
• Waiting until after ratification to get fully underwritten. In a competitive situation, a fully underwritten preapproval is a strong advantage.

Also see what an appraisal gap is, since high-end homes can be harder to appraise. Your lender and a CPA can advise on your specific financing and tax picture.

Frequently asked questions

What is considered a jumbo loan in Northern Virginia in 2026?

Any loan above your county’s 2026 conforming limit. The national baseline is $832,750 and the high-cost ceiling is $1,249,125, and Northern Virginia counties fall in the high-cost range, so confirm the exact county figure with your lender.

How much do you need to put down on a jumbo loan?

It depends on the lender and loan size. Twenty percent is the most common, but some lenders offer 10% to 15% down options, often with stricter credit and reserve requirements.

Are jumbo loan rates higher than conventional rates?

Not always. The spread changes with market conditions and lender appetite, so get quotes for both jumbo and conforming options on the same day.

How many months of reserves do I need for a jumbo loan?

Many lenders want 6 to 12 months of the full housing payment, and more for larger loans or if you own other properties.
