How Much House Can You Really Afford?
Buying a home is one of the biggest financial decisions you’ll ever make. While many buyers focus on finding their dream home, the smarter first step is determining how much home they can comfortably afford.
Your budget depends on much more than your salary. Mortgage lenders evaluate your income, existing debt, credit history, down payment, and expected monthly housing expenses before deciding how much you can borrow. Even if a lender approves a certain loan amount, that doesn’t necessarily mean it’s the right amount for your personal financial situation.

The 28/36 Rule
Many lenders use what’s known as the 28/36 Rule.
It suggests that:
- Housing costs should generally stay below 28% of your gross monthly income.
- Total monthly debt payments should remain below 36% of your gross monthly income.
Housing costs include:
- Mortgage payment
- Property taxes
- Homeowners insurance
- PMI (if required)
- HOA fees
Keeping within these guidelines helps reduce financial stress and leaves room for savings and unexpected expenses.
Factors That Affect Home Affordability
Several variables influence the price range you can realistically afford.
Income
Higher household income generally increases purchasing power.
Existing Debt
Car loans, student loans, credit cards, and personal loans all reduce the amount available for housing.
Down Payment
A larger down payment lowers your mortgage balance, often resulting in lower monthly payments and better loan terms.
Interest Rate
Even a small increase in mortgage rates can significantly reduce purchasing power.
Property Taxes and Insurance
These recurring costs vary by location and should always be included in affordability calculations.
Why Getting Pre-Approved Isn’t Enough
Mortgage pre-approval tells you what a lender may be willing to lend—not necessarily what fits comfortably into your long-term financial plan.
A practical budget should also leave room for:
- Retirement savings
- Emergency fund
- Home maintenance
- Vacations
- Future family expenses
Many financial experts recommend buying less than the maximum amount you’re approved for if it helps maintain financial flexibility.
Tips to Improve Your Affordability
You may be able to increase your buying power by:
- Paying down existing debt
- Improving your credit score
- Saving for a larger down payment
- Comparing mortgage offers from multiple lenders
- Waiting for a lower interest rate environment when possible
Small improvements in these areas can have a meaningful impact on both loan approval and monthly payments.
Common Mistakes
Many first-time buyers make the same affordability mistakes:
- Shopping before setting a budget
- Ignoring taxes and insurance
- Forgetting maintenance costs
- Using net income instead of gross income
- Stretching to the maximum loan amount
Avoiding these pitfalls can make homeownership more sustainable over the long term.
