Frequently Asked Questions
How much house can a buyer afford?
Lenders generally cap housing costs at 28% of gross monthly income and total debt at 36–43% (DTI). Income, existing debts, rate, and down payment together set the ceiling — this calculator works it backward to a price.
What is included in the monthly housing payment?
PITI: principal, interest, property taxes, and insurance — plus HOA dues and mortgage insurance (PMI) when the down payment is under 20%. Taxes and insurance often add 20–30% on top of principal and interest.
How much does the interest rate change affordability?
Roughly 10% of buying power per 1% rate move. A buyer qualified for $400k at 6% qualifies for about $360k at 7% — which is why rate locks matter in rising markets.
