How Much House Can I Afford? It’s Really Two Questions

I get asked this all the time. And almost every time, I have to split it into two questions before I can answer it honestly.

How much can I qualify for? That’s a math problem. There’s a formula, a lender runs it, and it produces a number.

What can I actually afford? That’s a budget question. It’s about what you’re genuinely comfortable paying every month, once the excitement of house hunting wears off.

Sometimes those two numbers land in the same place. Often they don’t. And the gap between them is usually the difference between buying a house and being happy in it two years later.

What a lender actually counts

Most people come in thinking about the mortgage payment. Some have got as far as property taxes, homeowner’s insurance, and HOA dues if the property has them. If that’s you, you’re already ahead, and all of that is part of it.

Here’s the part that catches people out. We also count every other debt showing on your credit report.

Every liability on that report has a monthly payment attached to it. The car. Student loans. Credit card minimums. A personal loan you’d half forgotten about. All of those monthly payments get added to your new housing payment, and the total gets divided by your gross monthly income, which is income before taxes, not what lands in your account.

That ratio is what produces the number you qualify for. Not your salary on its own, and not the price of the house on its own.

Wondering how this applies to you? Ask my AI: “Does a car payment or student loan change what I can borrow?” →

Why this is worth doing with someone

It’s more of a process than a calculator.

Once we can see the whole picture, there’s usually something to work with. Sometimes we can map out which debt to pay down first, because paying off the right one can move your number more than paying off the biggest one. Sometimes it’s a different way of structuring the loan. Different programs have genuinely different limits, so the answer isn’t fixed.

That’s the part that’s hard to do on your own, and it’s where I come in.

A rule of thumb, with a real caveat

If you just want something to work with on the back of an envelope: take your gross monthly income and divide it in half.

That’s roughly the ceiling on your total monthly obligations that some programs will allow, and by total, I mean the new housing payment plus everything else on your credit report, not just the mortgage.

Now the caveat, and I mean this one. Some programs. Not all of them. Loan programs have different qualification limits, and the rule of thumb is a starting point for a conversation, not a number to go shopping with. Treat it as a way to sanity-check your thinking, then get the real number.

And that rule of thumb can’t see your credit report, which is the part that actually moves the answer.

You need more than a good rate

This is the thing I’d most like people to take away.

A good rate matters. But a rate is one line in a much bigger decision, and plenty of people chase the rate and end up in a house that makes them miserable every month.

What I want is for you to understand what you qualify for, understand what you’re actually comfortable with, and then decide, knowing both. That’s a plan. And a plan will serve you better than a quarter point ever will.

Common questions

The math above is the same for everyone. Yours isn’t. Ask about your own situation: the car payment, the student loans, whatever’s actually on your mind. It’s Mike’s AI, so it’s awake at 11pm, and it collects nothing.
