Common questions

How much house can I afford?

Work backward from a monthly payment you can live with: enter prices into the calculator until the full payment (including PMI and taxes) lands inside your budget. The common guardrail is keeping housing near 28% of gross income, but your comfort is the real constraint.

What is PMI and when do I have to pay it?

Private mortgage insurance, typically required when your down payment is under 20%. It adds meaningfully to the monthly payment, and the calculator includes it, which is exactly the part listing-site estimates leave out.

Why is my actual mortgage payment higher than the advertised one?

Advertised payments are usually principal and interest only. The bank actually collects principal, interest, PMI, and escrowed property taxes. This calculator shows the full number so the budget survives contact with reality.

How much difference does the interest rate make?

Compounded over 30 years, enormous: even half a percent moves the total cost by tens of thousands. Run the same house at two rates here and compare, which is the fastest way to understand rate-shopping's payoff.

Is this calculator connected to any lender?

No. Nothing you enter is collected or sold as a lead. Run as many scenarios as you like; nobody is going to call you.
