Keep track of multiple affordability setups.
Every $100/mo in existing debt reduces your max mortgage by roughly $20,000–$22,000. At $500/mo in debt payments, you've already lost $100k+ in borrowing capacity before a lender sees your application.
Front-end DTI: housing costs only — lenders cap at 28%. Back-end DTI: all debt including housing — capped at 43%. With existing debt, your back-end limit becomes the binding constraint, not your income.
1. Pay off the smallest debt first — frees up monthly cash fast. 2. Increase your down payment — smaller loan = lower payment. 3. Add a co-borrower — combines income and lowers your DTI ratio instantly.
