How Much House Can I Afford on a $170,000 Salary?
With a $170,000 annual salary, here's how much home you can afford using the 28/36 rule, and what your monthly payment would look like.
Home Affordability on $170,000/Year
Using the 28/36 rule — your PITI payment should stay under 28% of gross income, total debt under 36%:
| Monthly | Annual | |
|---|---|---|
| Gross income | $14,167 | $170,000 |
| Max PITI (28%) | $3,967 | $47,600 |
| Max total debt (36%) | $5,100 | $61,200 |
How Much Home Can You Buy?
At a 6.5% interest rate with a 30-year loan:
| Down Payment | Max Home Price | Monthly PITI | Notes |
|---|---|---|---|
| 20% | $613,000 | ~$3,968 | No PMI |
| 10% | ~$521,000 | ~$3,967 | Includes PMI |
| 5% | ~$490,000 | ~$3,967 | Includes PMI |
A larger down payment lets you afford a more expensive home because there’s no PMI eating into your monthly budget.
Impact of Existing Debt
If you have other monthly debt payments, your buying power drops:
| Monthly Debt | Available for PITI | Max Home (20% down) |
|---|---|---|
| $0 | $3,967 | $613,000 |
| $300/mo | $4,800 | ~$577,000 |
| $500/mo | $4,600 | ~$553,000 |
| $800/mo | $4,300 | ~$517,000 |
Every $300/month in existing debt reduces your buying power by roughly $36,000.
How Interest Rate Affects Affordability
On a $170,000 salary with 20% down:
| Rate | Max Home Price | Monthly PITI |
|---|---|---|
| 5.5% | ~$687,000 | ~$3,967 |
| 6.0% | ~$650,000 | ~$3,967 |
| 6.5% | $613,000 | ~$3,968 |
| 7.0% | ~$576,000 | ~$3,967 |
| 7.5% | ~$546,000 | ~$3,967 |
A 1% rate drop adds roughly $74,000 to your buying power.
Tips to Maximize What You Can Afford
- Pay off debt first — every $300/month in debt you eliminate adds ~$36,000 in buying power
- Improve your credit score — better scores get lower rates, which means more home for the same payment
- Compare lenders — rates vary 0.25-0.5% between lenders, which can mean $37,000+ in buying power
- Consider bi-weekly payments — won’t help you qualify, but saves thousands in interest after you buy
- Check your state — property taxes and insurance vary dramatically. See your state’s costs
