For years, the standard advice tilted one way: buy if you can, because renting is throwing money away.
New calculations are poking holes in that assumption, and the numbers are getting uncomfortable for anyone who bought the pitch without running the math.
The rent-versus-buy calculator from NerdWallet, which crunches mortgage rates, property taxes, maintenance, and closing costs against rent increases and investment returns, shows break-even horizons stretching past seven years in a growing list of metros.
In expensive coastal markets, the crossover point can push past a decade.
That matters because the median American homeowner moves roughly every eight to ten years.
If you sell before the break-even point, the transaction costs alone can wipe out whatever equity you built. **Why the Math Got Uglier** Mortgage rates hovering near 6.5% to 7% are the biggest culprit.
At those levels, a $400,000 loan costs about $2,530 a month in principal and interest before taxes or insurance.
Add in the costs buyers tend to forget: 2% to 5% of the purchase price in closing costs, 1% to 2% annually for maintenance, and 6% to 10% in selling costs when you leave.
Suddenly the "cheaper than rent" claim needs a lot of appreciation to hold up.
Property taxes and insurance have also climbed sharply in states like Florida, Texas, and California, where insurers have raised premiums or pulled out entirely.
Those costs hit owners, not renters. **Where Buying Still Wins** The calculator flips the other way in the Midwest and parts of the South.
In cities like Cincinnati, Kansas City, and Indianapolis, home prices remain low enough relative to rents that break-even can arrive in under four years.
The pattern is consistent: buying pays off fastest where prices are modest, rents are high relative to ownership costs, and you plan to stay put.
It loses where prices are stretched, taxes are steep, and you might move.
One overlooked factor is what you do with the money you don't sink into a down payment.
If renting frees up $60,000 that goes into an index fund returning 7% annually, that growth can rival or beat home equity in many markets. **What to Check Before You Decide** Run the calculator with your actual numbers, not national averages.
Plug in your real rent, the specific home price, your down payment, your credit score's rate, and how long you truly expect to stay.
If a job change, a growing family, or a relationship could move you in three years, the math rarely favors buying.
A new roof, a broken furnace, or a special assessment from an HOA can erase a year of supposed savings.
Renters hand those problems to someone else. **The Bottom Line** The rent-versus-buy question has no universal answer, and anyone who tells you otherwise is selling something.
What's changed is that the old default, buy whenever you can, no longer survives contact with today's rates and prices in many cities.
Run the numbers for your situation, your city, and your timeline.
Final Thoughts
The calculator won't tell you what to do, but it will show you what you're actually choosing between, and that's worth more than the folk wisdom it replaces.
