How Much House Can I Afford on a $100,000 Salary?
Using a common 28% housing guideline, a $100,000 salary supports about $2,333 a month in housing costs, roughly a $347,000 to $379,000 home depending on rates. Here's the math and what it leaves out.

Quick answer
Using the common 28% front-end guideline, $100,000 of gross income supports about $2,333 a month for principal, interest, taxes, and insurance. With 20% down, 1.1% property tax, and $2,000 a year insurance, that's roughly $379,000 at 6%, $363,000 at 6.5%, or $347,000 at 7%.
The calculation
| Mortgage rate | Approximate home price |
|---|---|
| 6.0% | $379,000 |
| 6.5% | $363,000 |
| 7.0% | $347,000 |
