The rent-versus-buy math just got a lot less friendly, and anyone staring at a calculator right now is probably getting a number they don't like.
Mortgage rates have been hovering in the mid-to-high 6% range for a 30-year fixed loan, according to Freddie Mac's weekly survey, after spending most of 2021 under 3%.
A $400,000 home bought at 3% carried a principal-and-interest payment near $1,686.
At 6.5%, the same house runs about $2,528 before taxes, insurance, or HOA dues.
Asking rents are up roughly 20% nationally since early 2021, per Zillow data, which is exactly why so many people opened a calculator in the first place. **The calculator isn't lying.
It's just incomplete.** Most online tools compare your rent to a mortgage payment and declare a winner.
They skip the stuff that actually drains accounts: closing costs that often run 2% to 5% of the purchase price, property taxes that reset after a sale, maintenance budgets of 1% of home value per year, and the fact that you pay interest-heavy payments early on.
Selling early can wipe out years of equity once agent commissions take their cut.
In many markets, you need to stay put five to seven years just to make buying cheaper than renting.
If your job, your relationship, or your tolerance for a bad neighbor could change before then, the math tilts fast. **The credit card is the hidden variable.** Here's what calculators rarely mention: down payments and closing costs often get financed by plastic or by draining savings that were covering an emergency.
With average credit card APRs above 20%, a $10,000 balance carried for a year costs over $2,000 in interest alone.
That's money that never touches your mortgage, your groceries, or your future.
Rent increases land on people who may also be carrying balances.
A $200 monthly rent hike and a $3,000 card balance can combine to squeeze a budget harder than a mortgage payment on paper suggests. **What to actually do this week.** Open a real calculator, not a headline.
NerdWallet, Zillow, and the New York Times all offer rent-vs-buy tools that let you input taxes, maintenance, and how long you'll stay.
Run your number three times: at 5 years, 7 years, and 10 years.
Call your landlord or check your lease before you assume rent will spike.

If you're carrying a balance, paying that down is a guaranteed return that no housing market can match.
And remember that "buying is always better" was a slogan built during a decade of near-zero rates.
That decade is over. **Our take:** The calculator is a starting point, not a verdict.
If you can't stay put for at least five years or you'd have to borrow to cover closing costs, renting and investing the difference is a legitimate, math-backed choice.

Run your own numbers before you let anyone—including a calculator—tell you what to do.
