The Quick Rule of Thumb
A commonly used starting point is the 28/36 rule: your total housing costs (mortgage, taxes, insurance) should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36% of gross monthly income. However, many lenders in 2026 approve buyers up to 43–57% DTI depending on loan type and compensating factors.
What Factors Determine Affordability?
- Gross Monthly Income — Before-tax income is what lenders use
- Monthly Debt Payments — Car loans, student loans, credit cards all reduce buying power
- Credit Score — Higher score = better rate = more house for the same payment
- Down Payment — More down reduces your loan amount and monthly payment
- Loan Type — VA loans often allow the most house due to $0 down and no PMI
- Property Taxes & Insurance — Summerville/Dorchester County rates factor into your total payment
