The right down payment on a Northern Virginia home is the largest amount that still leaves you comfortable cash reserves after closing. Twenty percent typically avoids conventional mortgage insurance, but 5% to 15% can be the stronger plan when it keeps your savings intact. Your loan type, rate, and goals decide it.

How Much Should You Put Down on a Northern Virginia Home?

How much should you put down on a Northern Virginia home?

The right down payment on a Northern Virginia home is the largest amount you can put down while still keeping comfortable cash reserves after closing. Twenty percent typically avoids conventional private mortgage insurance, but 5%, 10%, or 15% can be the smarter plan when it protects your savings. Your loan type, credit profile, and plans for the home decide the answer, not a rule of thumb.

Key Takeaways

  • Realtor.com's September 2026 report put the Prince William County median sold price at $595,000, so 10% down on a median-priced county home is $59,500.
  • On the $765,000 regional median from NVAR's August 2026 figures, 20% down is $153,000 and 5% down is $38,250, a gap of $114,750 in cash you either keep or commit.
  • Conventional loans with less than 20% down commonly carry private mortgage insurance, but the exact requirement and cost depend on your lender, loan type, credit, and loan-to-value ratio.
  • Down payment is only one part of the cash you need at closing, because prepaid items, inspections, and title company charges come on top of it.
  • A larger down payment can help an offer, but financing type, preapproval quality, earnest money, contingencies, and settlement timing all carry weight too.

When I sit down with buyers, the first thing I hear is "Don't I need 20%?" The answer for a Northern Virginia home is no, not necessarily. But the answer to "what's the right number for me?" takes a real look at your cash, your comfort level, and the loan you're using.

What do 3%, 5%, 10%, 15%, and 20% down look like on a Northern Virginia home?

On a $765,000 purchase, the range runs from $22,950 at 3% down to $153,000 at 20% down. On a $595,000 Prince William County purchase, it runs from $17,850 to $119,000. Here's the full math for both price points.

Down payment Down on $765,000 Financed on $765,000 Down on $595,000 Financed on $595,000
3% $22,950 $742,050 $17,850 $577,150
5% $38,250 $726,750 $29,750 $565,250
10% $76,500 $688,500 $59,500 $535,500
15% $114,750 $650,250 $89,250 $505,750
20% $153,000 $612,000 $119,000 $476,000

Financed amounts are approximate and before any loan-specific adjustments.

Where do these two price points come from?

The $765,000 figure is the NVAR regional median from August 2026. The $595,000 figure is the Prince William County median sold price from Realtor.com's September 2026 county report. Those are different geographies, different reporting methods, and different months, so don't treat them as a like-for-like comparison. Use them as two realistic price points to test your own plan against.

The same Realtor.com report listed 1,722 active listings and a median of 31 days on market in the county. That tells you homes are moving at a measured pace, which matters when you decide how much of your cash to commit to one purchase. Realtor.com is a portal, not an MLS, so I always pull current numbers for the specific part of the county you're shopping before you write an offer.

Is the down payment the same as the cash I need to close?

No. The down payment is the biggest piece, but you'll also pay lender-required prepaid items, inspection and appraisal-related charges, and title company fees. I break those categories down in my post on how much cash it takes to buy a house in Northern Virginia. Plan your down payment and your closing cash together, not one at a time.

How does each down payment level change your monthly payment, mortgage insurance, and reserves?

A bigger down payment lowers your loan balance and, with it, your principal and interest payment. It can also reduce or eliminate mortgage insurance, but it drains the cash you'd otherwise hold in reserve. Each step up the ladder buys you something and costs you something.

What happens to the monthly payment?

Every extra dollar down shrinks the amount you borrow, so the payment drops. On the $765,000 example, moving from 5% to 20% down cuts the loan from $726,750 to $612,000. I'm not putting a payment figure on the page, because a real comparison needs your interest rate, loan term, loan type, property taxes, homeowners insurance, mortgage insurance treatment, and any HOA dues. Change one of those and the answer moves. Your lender can run the side-by-side scenarios, and I'll help you read them.

When do you pay mortgage insurance?

Conventional loans with less than 20% down commonly require private mortgage insurance. Whether you pay it, what it costs, and when it can come off depend on your lender, credit profile, loan-to-value ratio, and the loan program. Other loan programs treat mortgage insurance differently, so confirm the specifics before you choose a percentage.

Don't assume 20% is a magic line you must hit. For some buyers, paying mortgage insurance for a period while keeping a solid cash cushion is the better tradeoff. Ask your lender to price a few down payment levels so you can see the difference in real numbers.

How do reserves factor in?

Your down payment and your reserves come out of the same pot. A buyer who drains nearly everything to reach 20% may have little left for repairs, moving costs, furniture, or a surprise expense in the first year. A buyer at 10% or 15% may have more breathing room. Lenders can also have their own reserve requirements, which vary by borrower and loan, so ask early.

Down payment Cash you keep Loan balance Mortgage insurance (conventional)
3% Most Largest Commonly required; program rules vary
5% High Slightly smaller Commonly required
10% Moderate Meaningfully reduced Commonly required; pricing depends on loan-to-value and credit
15% Lower Smaller still Commonly required, often at a lower cost
20% Least Smallest Typically avoided, subject to loan type and lender rules

Does a bigger down payment make your offer stronger on a Northern Virginia home?

It can help, but it rarely decides the outcome alone. Sellers and their agents look at the whole package, and the down payment is one piece of it. In my experience, a well-structured offer from a buyer with 10% down can compete with a sloppy offer from a buyer with 20%.

Here's what else carries weight when you make an offer on a Northern Virginia home:

  • Preapproval quality: a full lender review reads stronger than a quick prequalification.
  • Financing type: some loan types carry extra steps that sellers weigh.
  • Proof of funds: clear documentation shows your cash is real and ready.
  • Earnest money deposit: the size of your deposit signals commitment.
  • Contingencies: your inspection and financing terms shape the risk a seller sees.
  • Appraisal terms: how you handle a low appraisal matters. My post on a low appraisal in Northern Virginia shows how it plays out from the seller's side.
  • Settlement timing: a closing date that fits the seller's plans can matter as much as price.

The relative importance of each term changes from one transaction to the next. Before I'd advise you to stretch to 20% for offer strength, I want to see whether a cleaner timeline or stronger preapproval would do more for you, at less cost to your savings.

Can down-payment assistance change the math in Prince William County?

It can for buyers who qualify, but eligibility is narrow and it's not a general Virginia rule. The Virginia Department of Housing and Community Development publishes down-payment assistance program guidelines that spell out who qualifies.

One current guideline says buyers in certain income bands may need to contribute 1% of the purchase price from personal funds. It also says buyers with cash assets of 10% or more of the sales price may be ineligible for that program. Eligibility turns on the specific program, your income, your assets, first-time-buyer status, household circumstances, and other requirements.

That has a real planning consequence. If you're considering assistance, putting more of your own cash into the down payment could affect whether you qualify. Read the program guidelines and talk to a participating lender before you commit your savings. My overview of first-time home buying in Northern Virginia covers how that process starts.

How do you pick your number?

  1. Ask your lender to price several down payment levels, with the mortgage insurance quote included for each.
  2. Decide what cash cushion you want left after closing, and treat it as untouchable.
  3. Compare payment savings against the reserves you'd give up at each level.
  4. Check whether any assistance program you're considering limits your assets.
  5. Choose the level that gives you a payment you're comfortable with and cash you can live on.

Every buyer's numbers are different. The only way to land on the right percentage is to run your own scenarios with a lender, and I'm glad to walk you through them before you start touring homes.

FAQ

How much should I put down on a Northern Virginia home in 2026?

Put down the amount that lowers your payment to a level you're comfortable with while still leaving real cash in reserve. For some buyers that's 5%, for others 10% to 20%. Your lender can price several levels so you can compare them side by side.

Can I buy a Northern Virginia home with 3% or 5% down?

Often yes, depending on the loan program and your qualifications. On a $595,000 Prince William County home, 3% down is $17,850 and 5% is $29,750. Expect mortgage insurance on a conventional loan at those levels, and confirm eligibility with your lender.

How much is 10% down on a Prince William County home?

On the $595,000 median sold price reported by Realtor.com for September 2026, 10% down is $59,500, leaving a loan of about $535,500. Your actual price will depend on the home you choose, and the down payment is separate from your closing cash.

Is 20% down worth it in Northern Virginia?

It's worth it if you can reach it and still keep healthy reserves. Twenty percent typically avoids conventional private mortgage insurance and gives you the smallest loan, but it can leave you short on cash for repairs and moving. If reaching 20% empties your savings, a lower down payment may be the safer plan.

Should I keep cash reserves instead of putting more money down?

For many buyers, yes. Reserves cover repairs, moving costs, and emergencies, while extra down payment is hard to get back out of the house. How much to keep depends on your situation and your lender's requirements, so decide on a reserve target before you pick a down payment.
