This article explains how to determine how much house you can afford when buying in Woodbridge VA and Northern Virginia. Affordability comes down to understanding your income, debts, down payment, and total monthly housing costs. Buyers should calculate their debt-to-income ratio (DTI), evaluate down-payment options, and account for taxes, insurance, and closing costs. A mortgage pre-approval gives you a clear budget and strengthens your offer in competitive Northern Virginia markets like Woodbridge, Lorton, Lake Ridge, Montclair, and Manassas.Key points for buyers:
Know your DTI and target 36% or lower

Q1: How do I calculate how much house I can afford in Woodbridge VA?
A: Start by calculating your debt-to-income ratio and estimating your monthly PITI payment. Then compare that number to your income and savings.
Q2: What DTI ratio do lenders prefer in Northern Virginia?
A: Most lenders want a DTI at or below 36%, though some programs in VA, MD, and DC allow higher depending on credit and reserves.
Q3: How does my down payment affect affordability in areas like Dumfries or Lorton?
A: A larger down payment reduces your monthly mortgage payment and may remove PMI, increasing your buying power.
Q4: Are zero-down or low-down-payment programs available in NOVA?
A: Yes—VA loans often allow 0% down, and FHA loans can require as little as 3.5%.
Q5: How much should I budget for closing costs in Prince William County?
A: Expect closing costs between 2–5% of the purchase price, depending on lender fees, taxes, and prepaid items.
