What This Means
Home affordability is primarily determined by the 28% front-end debt-to-income (DTI) ratio used by conventional lenders — meaning your total monthly housing costs (principal, interest, taxes, and insurance) should not exceed 28% of your gross monthly income. On a $100,000 salary, that's $2,333/month for housing. FHA loans use a more generous 31% DTI limit, which is why the FHA maximum of $360,000 is higher than the conventional limit of $330,000. These calculations assume a 6.875% fixed rate, 30-year term, 1.2% annual property tax, and $1,400/year homeowners insurance. Keep in mind that other monthly debts — car payments, student loans, credit cards — reduce the amount you can borrow, as lenders also consider your total (back-end) DTI ratio, typically capped at 36–43%.
