## With taxes

**Assumes the $100,000 loan is 80% of a $125,000 purchase (20% down, so no PMI).**

| Principal and interest | $477.42 |
| --- | --- |
| Property tax 0.89% a year, estimate | $92.71 |
| Homeowners insurance | not included |
| Monthly subtotal before insurance/HOA | $570.12 |

No state chosen, so this is an estimate: the U.S. ratio of median real estate taxes paid to median home value (ACS 2024 1-year). Insurance is left out until you choose a state (NAIC 2023 state averages) or add your own quote.

## Income needed

To keep the $570.12 monthly housing cost at 28% of gross income, you'd need about **$24,434 a year**. Lenders also cap total debt payments near 36% of income, so car and student loan payments reduce what you can borrow.
