How Much House Can I Afford?

This is one of the most consequential financial questions you will ever ask. And I want to give you an honest framework rather than the number that makes you feel excited about a home you may not actually be able to sustain.

There is a difference between what a lender will approve you for and what you can comfortably afford. Those are not the same number. And confusing them is one of the most common ways people end up house-poor, meaning they own a home but have nothing left over for everything else in their lives.

Here is the framework that actually works.

The traditional guideline is that your total housing costs, which includes your mortgage principal, interest, property taxes, homeowners insurance, and any HOA fees, should not exceed 28% of your gross monthly income. This is called the front-end debt-to-income ratio.

If your gross monthly income is $7,000, 28% of that is $1,960. That is your maximum comfortable housing payment by this guideline.

The second number to know is your total debt-to-income ratio, which includes all your monthly debt payments (housing, car loans, student loans, credit cards) compared to your gross monthly income. Most lenders want this below 43%, and most financial advisors suggest staying below 36% for real financial flexibility.

Now here is what the mortgage amount calculation looks like. If you can afford a $2,000 monthly mortgage payment and current 30-year fixed rates are around 6.6%, you can afford a mortgage of approximately $310,000 to $320,000. Add your down payment on top of that to determine the home price you can actually sustain.

Speaking of down payments. The standard recommendation is 20% down to avoid private mortgage insurance (PMI), which adds cost to your monthly payment without building equity. But programs like FHA loans allow as little as 3.5% down for buyers with a credit score of 580 or higher. Lower down payment means more accessibility, but also more cost over time in insurance and potentially higher rates.

A few things that people forget to factor into affordability.

Property taxes vary wildly by location. A $400,000 home in a high-tax state might carry $600 or more per month in property taxes. In a low-tax state, $200. That is a $400-per-month swing in your real housing cost.

Maintenance. The standard guideline is to budget 1% to 2% of your home's value per year for maintenance and repairs. On a $400,000 home, that is $4,000 to $8,000 per year, which needs to live somewhere in your budget.

Here is the question worth sitting with before you go to a lender. What monthly payment would let you still live the life you want? Not the maximum payment the lender will approve. The payment that leaves room for savings, for experiences, for everything that makes life worth working for.
