Buying a New Home? Here’s How to Know What You Can Afford

Most homebuyers, especially first-timers, begin their search the wrong way. They fall in love with the neighborhood, look around for sales, and then decide if any options are feasible. And more often than not, that’s where budget trouble begins.

The emotional investment enters the homebuying process pretty quickly. And when it does, having an honest budget conversation becomes more difficult. The reliable approach here is to be clear about your numbers even before you start browsing listings. The strategies below can help you make a purchase that truly makes sense.

Look Beyond Your Income

Income is where you start judging your affordability. Lenders look at your gross income (pre-tax earnings), retirement deductions, and insurance contributions to decide the loan amount you can get. A home affordability calculator can help you set a clear affordability benchmark based on your actual finances. Once you start running the finances every month, the real picture becomes clearer.

Therefore, look beyond your gross income to decide if you can afford the property you are eyeing. The best strategy is to compare the estimated running costs with the take-home income (after all the deductions).

Health insurance premiums, retirement contributions, childcare expenses, and state or local taxes can reduce your paycheck significantly before housing costs are accounted for. A mortgage payment that looks manageable against your gross income can feel tighter once it joins your monthly expenses.

Use the 28/36 Rule

A widely followed threshold for affordability is what homeowners know as the 28/36 rule. Here’s what it means in practice.

In essence, the rule says that your total housing expenses shouldn’t exceed 28% of your pre-tax income. Meaning, everything from your mortgage payments to property taxes, insurance, and association fees shouldn’t amount to a figure that exceeds your monthly gross earnings. Moreover, your total debt should stay below 36% of your total annual income. So if you’re already paying car loans, personal loans, student loans, or other debts, the mortgage payments alongside them can be a problem if the total exceeds 36%.

Pay Attention to the Down Payment Size

Your down payment amount does more than just reduce your loan. It also affects the total interest you’ll pay during the loan tenure, your monthly payments, and whether you will owe private mortgage insurance (PMI). For new buyers, PMI is the monthly premium most lenders will require when you pay less than 20% of the property’s purchase price. Your PMI will contribute to your housing costs over the long run until you have accumulated enough equity to remove it.

Generally, PMI ranges between 0.5% and 1.5% of the loan amount annually. It’s not a very alarming thing, but it’s worth considering when you’re deciding whether you can afford the new house. The PMI will become a part of your monthly expenses from the day you become a homeowner. So, it’s better to include it in your affordability conversations beforehand rather than have the amount come as an unpleasant surprise after closing.

Understand That the Purchase Price Isn’t the Full Cost

It’s common among new buyers to treat the mortgage payments and purchase price as the entirety of their home costs. In reality, the financial commitment includes additional upfront costs and ongoing expenses that go beyond the closing costs. Closing costs alone, which include inspection fees, appraisal fees, title insurance, and attorney fees, typically range from 2% to 5% of the purchase price. On a $350,000 home, that can mean $7,000 to $17,500 due at the time of closing.

Once ownership transfers, there are multiple other expenses to bear. Think property taxes, utility bills, maintenance costs (both planned and unplanned), homeowners’ insurance, and other expenses for upkeep. The amounts will vary each year, but having a fair estimate in mind and assessing affordability based on it is how you can make a smart purchasing decision.

Remember That Affordability Has to Hold Up Over the Long Run

A home mortgage is a long-term commitment. If you’re judging affordability simply based on your current income and expenses, it’s a drastic mistake. Life’s unpredictable, and there can be changes with real financial consequences.

A responsible affordability assessment accounts for those changes. So, ask yourself whether you can truly afford the home for years to come:

• Is income growth probable?
• Is there a credible scenario where your income holds flat or declines?
• Can there be any significant expenses two or three years out, like growing a family or pursuing further education?

These aren’t just what-ifs. They’re the kind of shifts that consistently reshape homeownership costs, and the sooner you address them, the better. Maintaining an emergency fund that covers three to six months of housing expenses provides a cushion against unexpected repairs, medical bills, or temporary gaps in income.

Closing Thoughts

Understanding what you can realistically afford isn’t limiting your aspirations. It’s the foundation that makes them achievable and helps you ensure that your future is financially solid. Wanting to feel settled in a new home over time comes with planning from the moment you decide to buy a house.
