How much house can I afford?
There is no single number. A lender will tell you the most you can borrow based on your debt-to-income ratio, but that ceiling is almost always higher than what you would actually be comfortable paying every month. The number worth knowing comes from your real budget, not from a multiple of your income.
The two different questions
What will a lender approve? That is arithmetic. Your income, your existing debts, your credit, your down payment. It produces a maximum.
What can you actually live with? That depends on things no underwriter sees. What you spend on childcare. Whether you travel. How much you want left over at the end of the month. How stable your income feels to you rather than on paper.
Almost everyone gets told the first number and then has to guess at the second one alone. That gap is where people end up house poor, and it is entirely avoidable.
Work it out from your actual budget
We built a free tool for this. You set a plan for each spending category, track what you actually spend, and set savings goals like a down payment or an emergency fund. Once it has a few months of your real numbers, it gives you an affordability estimate built on what you genuinely spend rather than on an assumption.
It is free, your data stays private, and there is no application attached to it. Plenty of people use it for a year before they are ready to buy anything.
What actually moves the number
- Your existing debts. A $600 car payment costs you meaningfully more buying power than most people expect.
- Your down payment. Lowers the loan amount, and above 20% on a conventional loan it removes mortgage insurance.
- Property taxes and insurance. These vary a lot across metro Atlanta and they are part of your payment, not an extra.
- Your loan program. What you qualify for on a conventional loan and what you qualify for on a program built for your situation can be two different numbers.
Common questions
How much house can I afford?
There is no single number. Lenders cap you based on your debt-to-income ratio, but that ceiling is usually higher than what you would actually be comfortable paying. The useful answer comes from your real budget, not from a multiple of your salary.
What is debt-to-income ratio?
Your total monthly debt payments divided by your gross monthly income. It includes the new mortgage payment plus car loans, student loans, credit card minimums, and child support. It does not include utilities, groceries, or insurance premiums other than those escrowed with the mortgage.
Does a bigger down payment mean I can afford more house?
It helps in two ways. It lowers the loan amount, which lowers the payment, and above 20% on a conventional loan it removes mortgage insurance. But it is not the only lever, and draining your savings to hit 20% is often the wrong trade.
Should I borrow the maximum I qualify for?
Usually not. Qualifying is a lender calculation. Affording is a life calculation, and the two are rarely the same number. The gap between them is where people end up house poor.
Is the budget tool free?
Yes. It is free, your data stays private, and there is no application involved. It is an educational tool, not financial planning advice.
Affordability estimates are for educational purposes only and do not constitute a loan approval, commitment to lend, or offer of credit. Strategic Budget & Goals is a free educational tool and is not financial planning, investment, tax, or legal advice. This is not a commitment to lend. Rates, programs, and terms are subject to change without notice. All loans are subject to credit approval and property qualification.
