How Much House Can I Afford in Northern Virginia? (With Calculator)
By Ken Byrne, NMLS #187129 · ALCOVA Mortgage LLC, NMLS #40508 · Updated May 2026
Quick Answer: In Northern Virginia, most buyers can afford a home priced at roughly 3.5 to 5 times their gross annual income — but the real number depends on your debts, down payment, credit score, and the property taxes and HOA fees of the specific county. On a $120,000 salary with moderate debt and 10% down, expect to qualify for around $440,000–$500,000 in 2026. Use the calculator and salary tables below to find your exact range.
Key Takeaways
- The 28/36 rule is the lender baseline: housing costs ≤ 28% of gross income, total debt payments ≤ 36%.
- DTI is the most important number — Northern Virginia lenders typically cap qualifying DTI at 43%–50% depending on loan type.
- Property taxes vary by county — Fairfax (~1.12%), Loudoun (~0.98%), Prince William (~1.07%), Arlington (~1.013%), Alexandria (~1.135%).
- HOA dues are part of DTI in NOVA — communities like Brambleton, Broadlands, and Reston can add $150–$400/month.
- VA loans let qualifying veterans buy with $0 down up to $1,249,125 in the DC metro for 2026.
- Pre-approval is the only way to know your exact number — calculators are estimates, underwriting is the answer.

If you're house-hunting in Northern Virginia, the first question isn't what you want — it's what you can actually afford. And in a market where the median single-family home in Fairfax County sits well above $750,000 and Loudoun County continues to attract relocating tech and government workers, getting that number right matters more here than almost anywhere else in the country.
The good news: affordability isn't a mystery. It's a formula built on four variables — your income, your debts, your down payment, and the interest rate you qualify for — plus a handful of NOVA-specific factors like county property tax rates and HOA dues that can quietly shift your maximum purchase price by tens of thousands of dollars.
This guide walks you through every piece of that math, gives you realistic salary-by-salary affordability tables for 2026, and shows you how lenders here in the DMV actually decide what you can borrow.
The Quick Formula for NOVA Affordability
Most Northern Virginia buyers can comfortably afford a home priced between 3.5x and 5x their gross annual income, assuming a reasonable down payment and minimal other debt. The exact multiplier depends on three things:
1. Your debt load. A single buyer with no student loans and no car payment can usually stretch closer to 5x income. A buyer with $700/month in combined debt payments may be limited to 3.5x.
2. Your down payment. 20% down avoids PMI and lowers your monthly payment, raising what you can afford. 3%–5% down works on conventional or FHA loans but adds mortgage insurance to your monthly cost.
3. The interest rate environment. Every 1% change in mortgage rates moves your buying power by roughly 10%. Rates have been volatile through 2025–2026, so locking in pre-approval gives you a real number, not a guess.
Calculators give you a starting estimate. Pre-approval gives you a number you can actually take to a listing agent.

Affordability by Salary (2026 Tables)
The table below shows realistic home price ranges across common Northern Virginia income tiers. Numbers assume a 720+ credit score, 10% down, $400/month in other debts, and illustrative rates near current 2026 levels. Your actual qualification will vary.
| Annual Salary | Conservative | Comfortable | Stretch | Est. Monthly PITI |
|---|---|---|---|---|
| $80,000 | $260,000 | $310,000 | $355,000 | $1,900–$2,400 |
| $100,000 | $340,000 | $400,000 | $455,000 | $2,400–$3,000 |
| $120,000 | $420,000 | $480,000 | $550,000 | $2,900–$3,600 |

| $250,000 | $880,000 | $1,000,000 | $1,140,000 | $6,000–$7,500 |
Illustrative ranges only. Based on 10% down, 720+ credit, $400/mo other debts, and rates near 7% APR. Your actual qualification depends on credit, debts, reserves, and current rates.
Visualizing the Spread: $120K Salary in NOVA
Here's how a $120,000 household stretches across price tiers based on debt load:
Every $100/month in monthly debt payments costs you roughly $18,000–$20,000 in buying power. Paying down a car loan before applying can directly raise your maximum purchase price.

The 28/36 Rule Explained
The 28/36 rule is the most widely used affordability benchmark in mortgage lending. It says:
28% rule (front-end DTI): Your total monthly housing payment — principal, interest, taxes, insurance, HOA — should not exceed 28% of your gross monthly income.
36% rule (back-end DTI): Your total monthly debt payments — housing PLUS credit cards, car loans, student loans, and other obligations — should not exceed 36% of your gross monthly income.
Here's what that looks like in practice for a $120,000 NOVA household ($10,000/month gross):
| Ratio | Monthly Cap | Covers |
|---|---|---|
| 28% front-end | $2,800 | PITI + HOA |
| 36% back-end | $3,600 | All debt payments combined |
Most loan programs will let you stretch beyond 36% — conventional loans often allow up to 45%, FHA up to 50%, and VA loans evaluate residual income rather than strict DTI caps. But the 28/36 rule remains the benchmark for whether a home is genuinely affordable, not just qualifyable.
What Lenders Actually Look At
Beyond the 28/36 rule, underwriters evaluate five core factors:
W-2 income is straightforward. Self-employed buyers typically need a two-year average from tax returns. Bonus and commission income requires two-year history to count.
Total monthly debt obligations divided by gross monthly income. Conventional and FHA loans use both front-end and back-end ratios.
740+ unlocks the best pricing on conventional loans. 620 is the conventional floor, 580 for FHA (3.5% down), 500 for FHA (10% down). VA loans have no official minimum but most lenders require 580–620.
Larger down payments lower your monthly payment and remove PMI. Most lenders also want to see 2–6 months of mortgage payments in reserves after closing.
Most lenders want two years in the same field. Job changes within the same industry are fine. Gaps require explanation but aren't disqualifying.
Northern Virginia Cost Factors That Surprise Buyers
Two buyers with identical incomes can qualify for very different homes in NOVA depending on which county they shop in. Here's why.
Property Tax Rates by County (2026)
| County / City | Effective Tax Rate | Annual Tax on $700K Home |
|---|---|---|
| Loudoun County | ~0.98% | $6,860 |
| Arlington County | ~1.013% | $7,091 |
| Prince William County | ~1.07% | $7,490 |
| Fairfax County | ~1.12% | $7,840 |
| City of Alexandria | ~1.135% | $7,945 |
Effective rates are illustrative and may shift annually. Confirm current millage with your county assessor.
That $1,000+ annual difference between Loudoun and Fairfax translates to roughly $85/month — which can swing your maximum loan amount by $12,000–$15,000.
HOA Dues — The Hidden DTI Killer
Lenders count HOA dues as part of your front-end DTI. In planned communities common to NOVA, this matters:
- Brambleton (Loudoun): $200–$280/month — includes high-speed internet, pools, trails.
- Broadlands (Loudoun): $130–$180/month plus tot-lot and pool fees.
- Reston (Fairfax): $750–$850/year (RA dues), but cluster-level HOAs can add more.
- Lake Ridge (Prince William): $90–$130/month.
- Condos in Arlington/Alexandria: $400–$700+/month is typical.
A $400/month condo fee reduces your max purchase price by roughly $70,000–$80,000 compared to a no-HOA single-family.

How Loan Type Changes Your Number
Your loan program directly affects what you can afford. The 2026 DC metro high-cost limits matter especially for higher-priced NOVA purchases:
| Loan Type | Min. Down | Min. Credit | Loan Limit (DC Metro) | Best For |
|---|---|---|---|---|
| Conventional | 3% | 620 | $1,249,125 | Strong credit, flexible terms |
| FHA | 3.5% | 580 | $1,149,825 | Lower credit, smaller down |
| VA | 0% | 580–620* | $1,249,125** | Eligible veterans, active duty |
| USDA | 0% | 640 | Income-based | Rural NOVA (outer Loudoun, Prince William) |
| Jumbo | 10–20% | 700+ | Above $1,249,125 | High-priced NOVA homes |
*Lender overlay; VA itself has no minimum. **No cap with full entitlement; conforming limit applies only when entitlement is partial.
For most NOVA buyers, conventional and FHA cover the bulk of purchases. Veterans gain enormous buying power through VA loans — zero down on a $700,000 home means $0 out of pocket for the down payment, freeing up cash for closing costs and reserves.
Affordability Mistakes to Avoid
❌ Maxing out your DTI. Just because a lender approves you at 45% DTI doesn't mean you should buy at that level. NOVA living costs — childcare, commuting, taxes — leave little room above 36% in real life.
❌ Forgetting closing costs. Virginia recordation tax, grantor tax, title insurance, lender fees, and prepaids typically add 2–4% of the purchase price. On a $500K home, that's $10,000–$20,000 beyond your down payment.
❌ Ignoring HOA dues. They count in DTI and your monthly budget. A $300/month HOA is a real $3,600/year that competes with property taxes for your housing budget.
❌ Trusting online calculators only. They use national averages. NOVA property taxes, HOA dues, and Virginia-specific closing costs push real-world numbers higher than generic estimates.
❌ Shopping before pre-approval. Sellers in this market won't take an offer seriously without a verified pre-approval letter — and you don't want to fall in love with a $650K home if you actually qualify for $520K.
How to Increase What You Qualify For
If your number comes in lower than you'd like, there are several levers you can pull before applying:
Knocking out credit card balances has the biggest immediate impact — every $100/month freed up adds $18K–$20K in buying power.
Moving from 680 to 740 can save 0.25–0.5% on your rate — which is meaningful buying power over a 30-year loan.
Hitting 20% removes PMI on conventional loans and shrinks your monthly payment, which raises the price you can support.
A spouse, partner, or qualifying family member can bring additional income into the calculation. Their debts and credit also count, so this works best when both are financially strong.
Virginia Housing's DPA Grant, DC HPAP (up to $202,000 in assistance), and the Maryland Mortgage Program can reduce out-of-pocket costs and free up cash for closing or reserves.

The Bottom Line
Affordability in Northern Virginia is a balance: your income gives you the ceiling, your debts and county-specific costs set the floor, and your loan type determines how far you can stretch in between. The buyers who get the best outcomes here aren't necessarily the ones with the biggest paychecks — they're the ones who go through underwriting before they fall in love with a house.
Pre-approval takes 15 minutes online and costs nothing. It gives you a verified number, a rate scenario you can actually compare against, and a letter that puts you on equal footing with cash buyers when you write an offer. In a market this competitive, that's not optional — it's the starting line.

Frequently Asked Questions
How much house can I afford on a $100,000 salary in Northern Virginia?
With moderate debt ($400/mo), 10% down, and a 720+ credit score, you can typically qualify for a home priced between $340,000 and $455,000 in NOVA. The exact figure depends on the county (property tax rate), HOA dues, and current interest rates.
How much house can I afford on a $150,000 salary in the DMV?
A $150,000 household with light debt and 10% down can usually qualify for $520,000–$680,000. That covers most townhouses in Fairfax and Loudoun and many single-family homes in Prince William or outer Loudoun.
What credit score do I need for a mortgage in Virginia?
Conventional loans require 620, FHA allows down to 580 with 3.5% down (or 500 with 10% down), and VA loans have no official minimum though most lenders set 580–620. Best pricing kicks in at 740+ on conventional.
How much down payment do I need in Northern Virginia?
As little as 0% for VA and USDA-eligible buyers, 3% for conventional, and 3.5% for FHA. 20% down avoids PMI on conventional loans. On a $500,000 NOVA home, that ranges from $0 to $100,000 depending on loan type.
What is the conforming loan limit in the DC metro for 2026?
The 2026 high-cost conforming loan limit for the DC metro area is $1,249,125 for a single-family home. FHA's high-cost limit is $1,149,825. Loans above these limits are considered jumbo and have stricter requirements.
What is a good DTI ratio for buying a house in NOVA?
Lenders cap qualifying DTI at 43%–50% depending on loan type, but 36% or lower is considered comfortable. NOVA's higher cost of living — taxes, childcare, commuting — makes 36% a more realistic ceiling for long-term sustainability.
How are property taxes calculated in Fairfax County?
Fairfax County's effective real estate tax rate is approximately 1.12% of assessed value as of 2026. On a $700,000 home, that's roughly $7,840 per year — escrowed monthly with your mortgage payment at about $653/month.
Do HOA fees count against my mortgage qualification?
Yes. Lenders include monthly HOA dues in your housing payment (PITI + HOA = "PITIA") when calculating front-end DTI. A $400/month condo fee reduces your max purchase price by roughly $70,000–$80,000.
How do I get pre-approved for a mortgage in Northern Virginia?
Submit an application with income documents (W-2s, paystubs, or tax returns for self-employed), bank statements for assets, and authorization for a credit pull. With JB Financing, you can apply online in under 15 minutes and receive a verified pre-approval letter the same day.
What are typical closing costs for buying a home in Virginia?
Virginia buyers typically pay 2%–4% of the purchase price in closing costs, including state recordation tax, deed of trust tax, title insurance, lender fees, and prepaids for taxes and insurance. On a $500,000 home, expect $10,000–$20,000 in addition to your down payment.
How do I find a good mortgage lender in Northern Virginia?
Look for local market knowledge, transparent fee disclosure, responsiveness, and clear communication on loan options. Ken Byrne with JB Financing / ALCOVA Mortgage (NMLS #187129) is based in Northern Virginia and works with buyers across VA, MD, DC, and WV — providing direct access to a licensed loan officer rather than a call center.
Is it a good time to buy a house in Northern Virginia in 2026?
NOVA inventory has been gradually improving through 2025–2026, giving buyers more leverage than the peak frenzy of 2021–2022. Rates remain elevated compared to historic lows but have stabilized. The best time to buy is when your finances are ready and you've been pre-approved — market timing alone rarely pays off.

PITIA: PITI plus Association (HOA) dues. Used when calculating housing payment for properties with mandatory HOA fees.
PMI (Private Mortgage Insurance): Insurance required on conventional loans with less than 20% down, protecting the lender if you default. Drops off automatically at 78% LTV.
Conforming Loan Limit: The maximum loan amount Fannie Mae and Freddie Mac will purchase. In DC metro for 2026, $1,249,125 for single-family.
Jumbo Loan: A mortgage exceeding the conforming loan limit. Stricter credit, income, and reserve requirements.
Front-End Ratio: Housing payment (PITIA) as a percentage of gross monthly income. The "28" in the 28/36 rule.
Pre-Approval: A lender's verified commitment to loan a specific amount based on reviewed income, credit, and assets. Stronger than pre-qualification, weaker than full underwriting approval.
