The 28/36 rule: How your debt impacts home affordability

Core Viewpoint - The 28/36 rule serves as a guideline for home affordability, suggesting that individuals should spend no more than 28% of their gross monthly income on housing costs and a maximum of 36% on total debt payments [2][13][20] Group 1: 28/36 Rule Overview - The 28/36 rule indicates that housing payments should not exceed 28% of gross monthly income, while total debt payments should not surpass 36% [2][18] - Housing payments include principal, interest, property taxes, and homeowners insurance, excluding other costs like repairs or utilities [3] - Mortgage lenders often use the 28/36 rule to assess borrowers' ability to make monthly payments, although many allow for higher thresholds [4][20] Group 2: Practical Example - For a household earning $120,000 annually (or $10,000 monthly), the 28/36 rule suggests a maximum monthly mortgage payment of $2,800 and total debt payments of $3,600 [5][9][14] Group 3: Debt-to-Income Ratio (DTI) - The 28/36 rule is a simplified representation of the debt-to-income (DTI) ratio, which measures the proportion of income that goes toward debt [6][18] - The front-end DTI ratio (28) reflects the percentage of income allocated to housing costs, while the back-end DTI ratio (36) encompasses all debt payments [7][18] Group 4: Loan Qualification - Different mortgage types have varying DTI ratio requirements; for instance, FHA loans may allow ratios up to 50%, while conventional loans typically cap at 45% for strong credit scores [8][10][19] - Exceeding the 28/36 rule may still allow for loan qualification depending on the mortgage program [20] Group 5: Improving DTI Ratio - Strategies to improve DTI ratio include paying down debts, increasing income, delaying home purchases, adjusting home search parameters, or bringing in a co-buyer [12][17]
