How much house can I afford?
The short answer: most buyers are constrained by monthly payment, not purchase price. Lenders usually look at income, monthly debts, credit score, down payment, taxes, insurance, and the current rate environment.
A quick rule of thumb is that housing costs often need to stay near 28% to 31% of gross monthly income, while total monthly debt usually needs to stay under 43%. That is not a law. It is just a common underwriting range.
If you want a useful answer, you need more than a rough multiplier. The difference between a 6.25% rate and a 7.25% rate can move affordability by tens of thousands of dollars.
