Rent vs Buy Math Is Changing Fast in 2025

Persona #5 ยท Vol: 0

For years, the standard advice was simple: renting is throwing money away.

That advice is now being tested in real time, and the numbers are not cooperating the way they used to.

Mortgage rates hovering near 6.5% to 7% have flipped the math in dozens of major metro areas.

A $400,000 home with 20% down at 6.8% costs roughly $2,100 a month before property taxes, insurance, and maintenance.

Closing costs, realtor commissions, and the first few years of a mortgage where most of your payment goes to interest can erase the equity you think you're building.

A rent vs buy calculator is only as good as the inputs you feed it, and most people feed it bad numbers.

They compare rent to a mortgage payment and stop there.

Here's what the honest version looks like.

Take your rent and add renter's insurance.

Then take the full cost of owning: mortgage principal and interest, property tax, homeowner's insurance, HOA fees, and a maintenance budget of 1% of the home's value per year.

Then factor in the things nobody puts on the listing sheet.

Closing costs run 2% to 5% of the purchase price.

If you move before year five, those costs alone can wipe out any appreciation you gained.

The break-even horizon is the number that matters most.

In expensive coastal metros, it's often seven to ten years right now.

In parts of the Midwest and South where prices are lower and rent is higher relative to home values, it can still be three to four years.

If your job, relationship, or life plan might change in three years, buying in a ten-year break-even market is a bet you probably won't win.

There's also the opportunity cost people ignore.

A down payment of $80,000 sitting in a high-yield savings account at 4% earns about $3,200 a year.

That's $266 a month working for you while you rent, and it doesn't call you about a broken water heater.

It means buying is a decision that deserves a spreadsheet, not a feeling.

The right answer depends on your market, your timeline, and how badly you want to paint the walls.

One more thing the calculators won't tell you.

Rents don't stay flat forever, and neither do home prices.

Final Thoughts

My take: run the numbers with a ten-year horizon and honest maintenance costs, then ask yourself if you'd still buy if the house appreciated zero percent.
