Washington DC mortgage FAQ
How much down payment do I need to buy a house in Washington DC?
Conventional loans start at 3% down, but anything under 20% requires PMI until you reach 20% equity — PMI auto-cancels at 78% of the original home value under the Homeowners Protection Act. FHA loans start at 3.5% down, and VA / USDA loans offer 0% down for eligible borrowers. Those are the national minimums: a lender can set a higher floor for this state or for a given loan size.
Why do property taxes vary so much within Washington DC?
Property taxes are layered by county, city and school district, so the effective rate differs block by block. The Washington DC state average is about 0.58%, but counties in our table above range widely — always confirm the exact bill with the local County Assessor.
When does PMI go away?
Under the Homeowners Protection Act (1998) you can request PMI removal at 80% LTV, and lenders must automatically cancel it when the balance reaches 78% of the original home value. This calculator estimates that month for you and shows the lower payment after PMI drops.
Does this calculator include home insurance for Washington DC?
Yes. The calculator pre-fills a typical Washington DC premium of about $1,500 per year and updates it when you switch counties. Risk is comparatively mild — severe summer thunderstorms and winter freeze/pipe damage are the main claims, which keeps premiums below the coastal states. Get real quotes before budgeting.
