How Much House Can I Afford at Current Mortgage Rates: A Practical Calculation Guide

Buying a home starts with one honest question: how much house can I afford at current mortgage rates? The answer is not a fixed number — it depends on your income, debts, down payment, and the rate your lender quotes today. Below is a clear framework to estimate your budget before you start viewing properties.

Start With the 28/36 Rule

Lenders typically follow the 28/36 guideline. Your monthly housing costs — principal, interest, property taxes, and insurance — should stay within 28% of gross monthly income. Total debt payments, including car loans and credit cards, should not exceed 36%.

Example: a household earning $7,000 per month can allocate roughly $1,960 to housing and about $2,520 to all debt combined. If existing debts total $600, the housing ceiling drops to $1,920.

Why Current Mortgage Rates Change Your Number

Mortgage rates directly affect purchasing power. At a 6% rate, a $2,000 monthly payment supports a loan near $333,000. At 7%, the same payment covers only about $300,000. That gap of $33,000 reflects pure interest cost, not a change in your income.

Use a mortgage calculator with today's rate, not last year's average. Even a 0.5% difference can shift your maximum home price by tens of thousands of dollars over a 30-year term.

Factor In the Full Cost of Ownership

Principal and interest are only part of the picture. Add property taxes, homeowners insurance, HOA fees, and maintenance reserves of 1–2% of home value annually. A $400,000 house may carry $500–$700 in non-loan costs each month.

Also budget for closing costs of 2–5% of the purchase price and keep an emergency fund of three to six months of expenses after closing.

Stress-Test Your Budget

Before committing, ask how much house you can afford if rates rise at renewal or your income dips. A comfortable budget leaves room for savings and unexpected repairs. Lenders may approve more than you should borrow — the final decision belongs to you.

Conclusion

Determining how much house you can afford at current mortgage rates requires three steps: apply the 28/36 rule, run the numbers at today's actual rate, and include taxes, insurance, and maintenance. A conservative estimate protects you from becoming house-poor and keeps long-term financial flexibility intact.
