Banks might approve mortgage payments up to 35% of your pretax income. Uber-conservative financial gurus advise limiting payments to less than 25% of your after-tax income. My middle-ground approach is to keep mortgage payments below 28% of your pretax income.


These questions often come up among first-time homebuyers:

  • What percentage of my monthly income can I afford to spend on my mortgage payment?
  • Does that percentage include property taxes, private mortgage insurance (PMI), or homeowners insurance?

Today I’ll tackle these questions to help make your home buying experience a little easier.

Consider Your Total Housing Payment, Not Just the Mortgage

Most agree that your housing budget should encompass not only your mortgage payment (or rent, for that matter), but also property taxes and all housing-related insurance — homeowner’s insurance and PMI.

What percentage of your income should that housing budget be? It all depends on who you ask.

What Others Say

The Traditional Model: 35% or 45% of Pretax Income

In an article on how the mortgage crash of the late 2000s changed the rules for first-time homebuyers, the New York Times reported:

“If you’re determined to be truly conservative, don’t spend more than about 35% of your pretax income on mortgage, property tax, and home insurance payments. Bank of America, which adheres to the guidelines that Fannie Mae and Freddie Mac set, will let your total debt (including student and other loans) hit 45% of your pretax income, but no more.”

I would hardly call 35% of your pretax income conservative, let alone ‘truly conservative.’

Let’s remember that even in the post-crisis lending world, mortgage lenders want to approve creditworthy borrowers for the largest mortgage possible. So when you obtain mortgage pre-approval, lenders will likely approve you for a loan amount with payments of up to 35% of your pretax income. That may tempt you to take on more home than you should. But don’t just assume that because the bank approved it, you can afford it. They are two very different things.

Remember: The more you spend on your home, the less you have available to save for everything else. You may be able to afford a housing payment that is 35% of your pretax income today, but what about when you have kids, buy a new car, or lose your job?

The Conservative Model: 25% of After-Tax Income

On the flip side, debt-despising Dave Ramsey wants your housing payment (including property taxes and insurance) to be no more than 25% of your after-tax income.

“Your mortgage payment should not be more than 25% of your take-home pay and you should get a 15-year or less, fixed-rate mortgage … Now, you can probably qualify for a much larger loan than what 25% of your take-home pay would give you. But it’s really not wise to spend more on a house because then you will be what I call “house poor.” Too much of your income would be going out in payments, and it will put a strain on the rest of your budget so you wouldn’t be saving and paying cash for furniture, cars, and education.”

Notice that Ramsey says 25% of your after-tax income while lenders are saying 35% of your pretax income. That’s a huge difference! Ramsey also recommends 15-year mortgages in a world where most buyers take 30-year mortgages. This is what I’d call conservative.

Another reader put it this way:

  • Your mortgage payment should be equal to one week’s paycheck.
  • Your mortgage payment plus all other debt should be no greater than two weeks’ paycheck.

That’s on the conservative side, too. One week’s paycheck is about 23% of your monthly (after-tax) income.

My Take: Somewhere in Between

Not everybody is as debt-averse as Ramsey. And his one-size-fits-all advice might shut out a huge segment of Americans from ever realizing their homeownership dreams.

Good luck finding a mortgage in California that you can pay off over a 15-year term, with monthly payments at less than 25% of your after-tax income. That approach will be unrealistic in a number of regional American housing markets with high home prices.

If I had to set a rule, it would be this:

  • Aim to keep your mortgage payment at or below 28% of your pretax monthly income.
  • Keep your total debt payments at or below 40% of your pretax monthly income.

Note that 40% should be a maximum. I recommend striving to keep total debt to a third of your pretax income, or 33%.

As some commenters have pointed out, while it may be possible to buy a decent home in a small midwestern town for $100,000 (and well within these ratios), buyers in New York or San Francisco will need to spend five times that amount just to get a hole in the wall. Yes, people tend to earn more in these high-cost-of-living areas, but not that much more. Does it mean they shouldn’t buy a home? Not necessarily. They’ll simply have to make trade-offs to buy in those areas.

How to Lower Your Mortgage Payment

Extend Your Mortgage Term

Choosing a longer mortgage term spreads your loan balance over more total payments, reducing the amount of each payment individually.

But remember, extending your term comes at a cost, as you’ll ultimately pay more in cumulative interest over the life of your loan.

Make a Bigger Down Payment

The bigger your down payment, the more equity you start off with in your home, and the lower your loan amount. A smaller loan = smaller monthly payments.

Plus, crossing the 20% down threshold means you don’t have to pay PMI, which will further reduce your combined housing costs.

Get a Better Interest Rate

The interest rate a lender offers you affects your monthly mortgage payment amount. If you nab a lower rate, you’ll make a lower monthly payment. Your chances of getting a better interest rate might increase in a few different scenarios:

Average Interest Rates Are Low

Average mortgage interest rates vary substantially from year to year, and have at times varied by as much as 2% within a mere six-month period.

Getting a fixed-rate mortgage at a time when interest rates are low can keep your monthly payments low.

Your Credit Score Increases

One surefire way to score a better interest rate is to improve your credit score. If you haven’t applied for a mortgage yet and your score has room for improvement, it might be worthwhile to wait six months or so for your credit score to climb up before you go for the mortgage.

If you already have a mortgage and your credit score has improved significantly since you originally took out the loan, you might be able to refinance for a better rate.

You Shop Around

There are oodles of options out there for mortgage lenders. Signing with your historical bank might give you the comfort and trust of familiarity, but it won’t necessarily give you the lowest rate you can find.

Always compare your bank’s offer with competing banks, credit unions, and reputable online lenders.

Finding the Right Lender

One place to start is with Credible, a site that allows you to get quotes from three lenders in only three minutes. There’s no obligation, but if you see a rate you like for your mortgage or refinancing your mortgage, you can progress to the next step of the application process. Everything is handled through the website, including uploading documents. If you want to speak to a loan officer, you can, of course, but it isn’t necessary. 

As you shop for a lender, remember that every dollar counts. You’re committing to a monthly mortgage payment based on the rate you choose at the very start. Even small savings on your interest rate will add up over the years you’re in your house. 

Fiona is another great place to get started since they allow you to shop and compare multiple rates and quotes with minimal information, all in one place. You’ll input the amount of the loan, your down payment, state, mortgage product type, and your credit score to get mortgage quotes from multiple lenders at once.


Can I Get a Mortgage If I Have Debt?

Having some degree of debt — like an auto loan — doesn’t disqualify you from getting a mortgage. But your DTI (debt-to-income ratio) certainly will influence how a lender evaluates your loan application. Generally speaking, a lender won’t approve you for a mortgage if your DTI is above 43%.

Personally, I advise you to hold off on a mortgage until your DTI is below 40% max. And a 33% DTI is an even better goal before applying for a mortgage. Going into a mortgage with a lower DTI gives you more financial breathing room in the event that unexpected expenses pop up.

What Is ‘House Poor’?

House poor is a financial circumstance in which a mortgager allocates too large a portion of their income toward homeownership expenses. This leaves the mortgager unable to live comfortably, and also puts them at risk of being unable to reach other financial goals.


Some financial gurus might say that the less of your income you devote to mortgage payments, the better. But taking an excessively conservative approach to mortgage payments might saddle you with a house or neighborhood that you’re unhappy with. On the other side of the spectrum, devoting too much of your income to your mortgage can put you in a financially vulnerable position, with little expendable income.

My broad guideline is to keep your monthly mortgage payment — including insurance and property taxes — at 28% of your pretax income. And try to keep your total debt payments, mortgage included, as close to 33% of your pretax income as possible.

There’s really no one-size-fits-all solution to mortgage budgeting. But you can start with my middle-ground approach and tailor it to align with your future financial goals and local housing market.
