Qualification depends on credit score, reserves, and lender guidelines. These are general thresholds, not guarantees.
Show the math
Front-end DTI covers only housing costs. Back-end DTI adds all other monthly debt. Both are divided by your gross monthly income to get the ratios lenders evaluate.
Front-end DTI = $1,800 housing ÷ $7,000 gross = 25.7%
Back-end DTI = ($1,800 + $0 other debts) ÷ $7,000 = 25.7%
You have $160 of headroom before hitting the 28% front-end threshold and $720 before hitting 36% back-end — the two limits most conventional lenders use.
