What Does a $500,000 House Actually Cost per Month? (At 6%, 7%, and 8% Rates)

Rate changes are brutal. A single point can add hundreds per month. Here's what a $500k home costs at 6%, 7%, and 8% rates, and why the rate slider matters more than most buyers expect.

Monthly cost at 6%, 7%, and 8%

RatePrincipal + interestEstimated PITI
6%~$2,997~$3,600
7%~$3,327~$3,950
8%~$3,669~$4,320

PITI is still the full story

Even if rates drop, property taxes and insurance remain. Always compare total PITI, not just principal and interest.

Rate changes shrink buying power fast

If rates rise, the same monthly budget buys less house. That's why rate sensitivity is the fastest way to evaluate affordability.
