Down payment help may be closer than you think

Thousands of down payment assistance programs exist across the country, from grants to forgivable loans. Many buyers qualify and never check.

These numbers are estimates to help you plan, not a loan offer. Monthly payment = principal & interest + PMI (under 20% down) + property tax + HOA; homeowners insurance is not included. Actual payments depend on your credit, loan program, location, and current rates. Always talk with a licensed lender for accurate numbers.

How this works

Each option is a different down payment percentage. In home-price mode, the calculator works forward to your monthly payment (principal and interest, plus PMI when you put down less than 20%, plus property tax and HOA). In budget mode, it runs the same math in reverse: given a monthly budget, it solves for the home price each down payment supports.

Putting more down lowers your loan and drops PMI at 20%, which is why a bigger down payment can stretch the same monthly budget further.

What this is and isn't

This is a planning tool, not a loan offer. It estimates principal, interest, PMI, property tax, and HOA; it does not include homeowners insurance, and real rates and costs vary by lender and location. Always confirm your numbers with a licensed lender.
