How Much Do You Need to Earn to Afford a $750,000 Home in South Dakota?
The 28% front-end DTI ratio is the conventional guideline used by Fannie Mae and Freddie Mac: your total housing payment should not exceed 28% of your gross monthly income. When you carry other debts, the 36% back-end DTI limit applies to all obligations combined. Source: Fannie Mae Selling Guide B3-6-02.
| Other Monthly Debts | Income Needed (20% down) | Income Needed (10% down) |
|---|---|---|
| No other debts | $195,312/yr | $235,909/yr |
| $300/mo | $161,900/yr | $193,500/yr |
| $600/mo | $171,900/yr | $203,500/yr |
| $1,000/mo | $185,233/yr | $216,833/yr |
These are qualifying thresholds, not comfortable ones. Lenders can approve borrowers at 43% DTI or higher with compensating factors — that doesn't mean you should borrow that much. Our honest recommendation: target a payment that's no more than 25% of your take-home pay, not gross income.
