How Much House Can You Actually Afford?

Real Numbers for 2026, Not Rules of Thumb

Generic affordability rules break down quickly once real rates, taxes, insurance, and debt are factored in. Here is how the actual math works right now.

Beyond the 28% Rule

Why Generic Affordability Rules Fall Short

Real Budgeting

The old rule of thumb that a mortgage payment should stay under 28 percent of gross monthly income is a reasonable starting point, but it does not reflect how lenders actually qualify buyers today. Lenders look at a debt-to-income ratio that includes the new mortgage payment alongside existing debt: car payments, student loans, credit card minimums, and any other recurring obligations, typically capping total debt at around 43 to 45 percent of gross monthly income, though this varies by loan program and lender.

This means two buyers with identical incomes can qualify for very different loan amounts depending on what other debt they are carrying. A buyer with no car payment and minimal credit card debt will typically qualify for meaningfully more house than a buyer with the same income and an existing car loan and student debt, even though their gross income is the same.

What a Payment Actually Includes

Principal and Interest Are Only Part of It

The Full Monthly Payment

A mortgage payment quoted as principal and interest alone understates the real monthly cost. Property taxes, homeowner's insurance, and, for many loans, private mortgage insurance if the down payment is under 20 percent, all get added into the full monthly payment lenders calculate against. In North Metro Atlanta, property tax rates and insurance costs vary meaningfully by county and even by specific subdivision, which is why two homes at the identical purchase price can carry different monthly payments.

HOA dues, where applicable, add another line item that affects what a buyer can actually afford, and are sometimes overlooked when buyers focus only on the mortgage quote from a lender, which typically does not include HOA fees in its estimate.

How Rate Changes the Math

Why the Interest Rate Environment Matters So Much

Rate Impact on Buying Power

Interest rate has an outsized effect on what a given monthly payment actually buys. A buyer targeting a specific monthly payment will qualify for a meaningfully larger loan amount when rates are lower, and a meaningfully smaller one when rates rise, even though the target payment itself never changed. This is why the same buyer's realistic price range can shift substantially over a period of months as rates move, independent of anything about their income or credit.

Buyers should get a current rate quote from a lender before setting expectations for a search, rather than relying on a rate they remember from a prior year or from a general news headline, since actual rates vary by credit profile, loan type, and lender.

Down Payment and Cash Reserves

What You Need in the Bank Beyond the Down Payment

Cash to Close

Beyond the down payment itself, buyers need cash for closing costs, typically 2 to 5 percent of the purchase price in Georgia, and most lenders want to see reserves remaining after closing, generally two to six months of mortgage payments in savings, depending on the loan program. A buyer who puts every available dollar toward the down payment and closing costs, leaving no reserve, can run into approval issues even with strong income and credit.

First-time buyers should also factor in the cost of moving, immediate repairs or updates, and furnishing a larger space than a prior rental, none of which show up in a lender's affordability calculation but all of which affect real financial comfort after closing.

Getting a Real Number

Why a Pre-Approval Beats Any Rule of Thumb

Know Your Real Number

The only reliable way to know what you can actually afford is a pre-approval from a lender, based on your real income, debt, credit, and the current rate environment, not a generic percentage rule applied to gross income. Billy works with buyers to get a realistic number before the search begins and can recommend local lenders familiar with North Metro Atlanta's specific tax rates and closing timelines.

Billy's Take

“The rule-of-thumb math and the real math almost never match anymore, especially with rates where they've been. I'd rather a buyer get a real pre-approval number in week one than fall in love with a home that number doesn't support.”
