1. The general rule of mortgage affordability

As a rule of thumb, you can typically afford a home priced two to three times your gross income. If you earn $100,000, you can typically afford a home between $200,000 and $300,000.

2. Factor in your downpayment

How much money do you have for a downpayment? The higher your downpayment, the lower your monthly payments will be. If you put down at least 20% of the home's cost, you may not have to get private mortgage insurance, which costs hundreds each month. That leaves more money for your mortgage payment.

3. Consider your overall debt

Lenders generally follow the 28/41 rule. Your monthly mortgage payments covering your home loan principal, interest, taxes, and insurance shouldn’t total more than 28% of your gross annual income. Your overall monthly payments for your mortgage plus all your other bills, like car loans, utilities, and credit cards, shouldn’t exceed 41% of your gross annual income.

4. Use your rent as a mortgage guide

The tax benefits of homeownership generally allow you to afford a mortgage payment—including taxes and insurance—of about one-third more than your current rent payment without changing your lifestyle. So you can multiply your current rent by 1.33 to arrive at a rough estimate of a mortgage payment.
