While many analysts, including Fannie Mae, predict rates could drop to 5.9% by year-end, geopolitical instability — specifically the current conflict in the Middle East — has sent rates on an upward trajectory this month.So, is right now a better time to buy, or should you wait? Buying now allows you to lock in a rate before further volatility spikes. Yet, three tax signals may determine whether you can afford a home in 2026.Become a smarter, better informed investor.

But your personal financial readiness may be the only variable you can control if you want to buy a house in 2026.Although it may seem counterintuitive to focus on the past when looking at a new home, your lender is doing exactly that. Lenders verify your last two years of tax returns to calculate your debt-to-income (DTI) ratio.Your DTI is calculated by dividing your total monthly debt payments (from your credit report) by your gross monthly income (before taxes).Example: If you earn $10,000 per month and have $4,000 in total debt (student loans, car payments, and your proposed mortgage), your DTI is 40%.Ideally, you want to sit at 36% or lower, though many conventional lenders accept up to 43%. So, before you ask yourself, "Should I lock in a mortgage rate now or later?" Calculate what your DTI is.If you need a house today and can afford the home at the rate you're approved for, lock it in. You may refinance your home later if the value is higher, but you can't "refinance" a missed opportunity on a home price that was within your DTI limits.A common mistake for homebuyers in 2026 is focusing solely on the mortgage principal and interest while ignoring the "escrow creep."Review all the categories of expenses that may go into your escrow account — including home insurance premiums and property taxes.In fact, your annual property tax bill is a good indicator of cost-of-living increases in your area. If a county has a history of aggressive reassessments, your "affordable" 2026 payment could become a burden later on.Additionally, you should only buy a home in 2026 if you plan to stay for at least five years. This period gives you a good chance that your home equity will grow enough to cover future closing and agent costs (if you decide to move).If you aren't sure you'll be in the area for five years, renting might actually be the better option for your financial situation. (Though some recent analyses suggest a 10-year runway for holding onto a home). Finally, don't forget to factor in insurance volatility. In states like Florida, some homeowners have seen premiums surge by about 49% over the last several years, per recent LendingTree data. If you don't bake these "hidden" costs into your DTI now, your dream home could quickly become a liability.Several federal tax shifts in 2026 have changed the math on home affordability. These shouldn't be viewed as year-end "bonuses," but as part of your monthly cash flow:It's important to note that these deductions are only available if you itemize and do not claim the standard deduction.But if you are eligible, incorporating these homeowner tax breaks alongside your projected property taxes, HOA fees, and insurance premiums, could give you a more realistic view of the "all in" home cost and whether you can truly afford your DTI mortgage rate in 2026.For the prepared homebuyer, 2026 may be the best window we've seen in years. Lower rates, higher inventory, and moderate price increases mean sellers may finally be ready to negotiate.However, your first step isn't browsing Zillow — it's reviewing your 2025 tax return. Ensure your income is documented, your DTI is optimized, and you're moving to an area where the property tax and home insurance (or even maintenance repairs) won't cannibalize your savings.And, of course, the amount of your down payment and your credit score will affect home affordability in 2026, too.Consult with a tax professional when necessary. Your personal financial situation ultimately impacts when it's time to move.Profit and prosper with the best of Kiplinger's advice on investing, taxes, retirement, personal finance and much more.
