Mortgage Payment on a $400,000 House
Estimate the payment on a $400,000 home with a sample down payment, rate, taxes, and insurance.
$400,000 home with $80,000 down
This example excludes HOA dues, mortgage insurance, closing costs, maintenance, utilities, and lender-specific escrow adjustments.
Build the payment in layers
Start with home price minus down payment to find the loan principal. The loan rate and term determine principal and interest. Then add realistic monthly estimates for property tax, homeowners insurance, mortgage insurance when required, and HOA dues.
- Principal and interest stay predictable on a fixed-rate loan.
- Taxes and insurance can change after purchase.
- Closing costs affect cash needed upfront even when they are not part of the monthly payment.
Why two $400,000 homes can cost differently
Location affects property taxes and insurance. Home type can add association dues or specialized coverage. The same price can also produce a different payment when the buyer changes the down payment, loan program, credit profile, or rate-lock timing.
Compare with a buffer
Use the calculator to test the quoted rate, then test a higher tax or insurance amount. A home budget should leave room for maintenance and normal changes in ownership costs rather than relying on the lowest possible estimate.
