How Much Income Do You Need for a $300k Mortgage?
The income needed for a $300,000 mortgage depends on your interest rate, loan term, taxes, and existing debt. However, there are general guidelines lenders use to estimate affordability.
A simple starting point
Many lenders prefer your total debt-to-income ratio (DTI) to stay below about 43%. Based on that, a common estimate is:
You may need roughly $70,000–$90,000 per year to comfortably afford a $300k mortgage
Why income requirements vary
The exact income needed can change based on:
- Interest rate
- Loan term (30-year vs 15-year)
- Property taxes and insurance
- Existing monthly debt
Example monthly payment
A $300,000 mortgage might result in a monthly payment around:
- $1,800–$2,300 per month (estimate)
This includes principal and interest, but your actual payment may be higher once taxes and insurance are included.
How lenders actually calculate this
Lenders don’t just look at income alone—they compare your income to your debts. That’s where your DTI comes in.
