Frequently Asked Questions
Why do some Virginia city names appear as county-level pages?
Virginia has independent cities that are separate taxing jurisdictions. The calculator keeps the existing state/county/city URL structure, so independent cities can appear at the county-level route when they are the primary local tax jurisdiction.
What Virginia assistance is modeled?
The state file models Virginia Housing's Down Payment Assistance Grant as a conservative purchase-price percentage estimate for eligible first-time buyers.
Why include Loudoun County?
Loudoun is a major Northern Virginia purchase market with high home values and strong mortgage volume.
Does this mortgage calculator include taxes and insurance?
Yes. This calculator estimates your full monthly housing payment by combining principal and interest with property taxes, homeowners insurance, and PMI when your down payment is below 20%. The result reflects a PITI-style payment rather than principal and interest alone, which helps you compare homes and loan scenarios more realistically before talking to a lender.
When does PMI apply on a mortgage?
Private Mortgage Insurance (PMI) typically applies when your loan-to-value ratio exceeds 80%, meaning your down payment is less than 20% of the purchase price. PMI is usually added to the monthly payment until you reach sufficient equity. This calculator includes PMI in the estimate when your inputs trigger it, so you can see how a smaller down payment affects affordability.
