Understanding Affordability

The 28/36 Rule Explained

Lenders use the 28/36 rule to determine how much you can borrow:

28%
Front-End Ratio

Your housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income.

36%
Back-End Ratio

Your total monthly debt payments (housing + car loans + student loans + credit cards) should not exceed 36% of your gross monthly income.

What Lenders Consider

  • Credit Score: Higher scores = better rates and larger loan amounts. 740+ gets the best rates.
  • Debt-to-Income Ratio: Lower is better. FHA allows up to 43%, conventional loans prefer under 36%.
  • Down Payment: 20% avoids PMI. FHA requires 3.5%, some loans allow 3%.
  • Employment History: 2+ years of steady income is preferred.
  • Cash Reserves: Having 2-3 months of mortgage payments saved helps.

How to Increase Your Budget

1

Pay Down Existing Debt

Reducing monthly debt payments improves your DTI ratio significantly.

2

Improve Your Credit Score

Better credit = lower rates = more buying power at the same payment.

3

Save a Larger Down Payment

More down = smaller loan = lower monthly payment = higher price point.

4

Consider a Longer Loan Term

30-year loans have lower payments than 15-year, allowing a higher budget.

Comfortable vs Maximum Budget

Just because you can afford a certain amount doesn't mean you should borrow that much.

Smart Strategy: Buy below your maximum to have financial breathing room for:
  • Unexpected repairs and maintenance
  • Emergency fund growth
  • Retirement savings
  • Lifestyle and travel
  • Future family changes

Frequently Asked Questions

A common guideline is that you can afford a home worth 2.5 to 3 times your annual income. So with a $100,000 salary, you could likely afford a $250,000-$300,000 home. However, this varies based on your debts, down payment, interest rate, and other factors.

Most lenders prefer a total (back-end) DTI of 36% or less, though some allow up to 43-50% with compensating factors. Your housing (front-end) DTI should ideally be 28% or less. Lower is always better for financial flexibility.

No, 20% is not required. Conventional loans allow as little as 3% down, FHA loans require 3.5%, and VA/USDA loans can be 0% down. However, putting down less than 20% usually requires PMI (private mortgage insurance), which adds to your monthly payment.

A typical mortgage payment includes PITI: Principal, Interest, Taxes, and Insurance. If you have an HOA or PMI, those are added too. Principal reduces your loan balance, while the rest are costs of homeownership.

A higher credit score qualifies you for lower interest rates. The difference between a 620 score and a 760+ score could be 0.5-1% in rate, which translates to tens of thousands of dollars over the life of your loan—and a lower monthly payment, which increases your buying power.
