“Should I rent or buy?” is one of the most-searched money questions there is — and most answers get it wrong by comparing a monthly rent to a monthly mortgage payment. That’s not the real comparison. The honest question is which path leaves you wealthier over the years you’ll actually live there, once you count every cost on both sides. This guide shows you how to run that comparison, how to find your break-even year, and what the 2026 market means for the decision. For instant numbers, use our free Rent vs Buy Calculator.

Why “Rent vs Mortgage Payment” Is the Wrong Comparison

If renting costs $2,200 a month and a mortgage payment is $2,400, it’s tempting to say renting wins by $200. But that comparison hides almost everything that matters. Buying carries costs a renter never pays — property tax, insurance, maintenance, closing and selling fees, and the opportunity cost of locking up your down payment. Buying also delivers a benefit renting never does: equity, the slice of the home you actually own, plus any appreciation when you sell. A fair comparison adds all of it up over time. That’s the difference between a gut feeling and a real decision.

The True Cost of Each Path

Here’s what genuinely goes into each side of the scale:

Cost to Buy = down payment + closing costs + every mortgage payment + property tax + insurance + maintenance + HOA − the equity you get back when you sell (after selling costs) + the opportunity cost of your upfront cash.

Cost to Rent = all the rent you’ll pay (rising a little every year) − the investment growth on the money you didn’t sink into a down payment.

Whichever total is lower over your time horizon is the cheaper option. Notice that both sides credit the money you didn’t spend — that’s what makes the comparison fair to renters, who can invest their savings instead.

Worked example — a 7-year stay

Say you’re weighing a $450,000 home with 20% down at a 6.22% rate against $2,200/month rent, and you’ll stay 7 years. Renting often looks cheaper for the first few years because of the huge upfront cost of buying — the down payment and closing fees alone are tens of thousands of dollars. But as the years pass, you build equity, the loan balance falls, and rent keeps climbing. Somewhere in the middle, the lines cross. That crossing point is everything.

The Break-Even Year: The Number That Decides It

The single most important output of any rent-vs-buy analysis is the break-even year — the point at which the total cost of buying drops below the total cost of renting.

• Before break-even: renting is cheaper. Buying’s upfront costs haven’t been recovered yet.
• After break-even: buying is cheaper. Equity builds, the mortgage shrinks, and rent compounds upward.

This gives you a clean rule of thumb: if you’ll move before the break-even year, rent. If you’ll stay past it, buy. It’s why the same house can be a smart buy for one person and a costly mistake for another — the only thing that changed is how long they stayed.

Worked example — break-even in action

If your break-even year comes out to 5, then leaving in year 3 means buying cost you more than renting would have — you paid the upfront costs but sold before the equity caught up. Stay 8 years, though, and buying pulls comfortably ahead. Our Rent vs Buy Calculator shows the exact year and a full year-by-year table so you can see precisely where the lines cross.

Opportunity Cost: The Hidden Factor Most People Miss

A down payment isn’t free money — it’s money that could have been invested. If you put $90,000 down on a home, that’s $90,000 that isn’t growing in an index fund. Economists call this the opportunity cost, and ignoring it makes buying look better than it really is. A proper rent-vs-buy comparison credits the renter with the growth that down-payment-sized sum could have earned. The calculator does this automatically using an investment-return assumption you control, so buying has to clear a genuinely fair bar.

Rent vs Buy in 2026

The market has reshaped this decision. With mortgage rates sitting around 6.22% and home prices high, buying costs noticeably more per month than renting in a lot of markets right now. But two things still favour ownership: buying locks in your housing cost while rent rises every single year, and every payment builds equity instead of a landlord’s. There’s no universal answer. Pricey coastal cities frequently favour renting; many inland and southern markets favour buying. The deciding factors are always the same three: how long you’ll stay, your local price-to-rent ratio, and your interest rate.

When Renting Is the Smarter Move

• You’ll move within a few years — not long enough to clear the break-even point.
• You want flexibility for career moves or uncertain plans.
• Home prices are very high relative to rents in your area.
• You’ll actually invest the difference and earn a solid return.
• You’d rather not deal with maintenance or the responsibilities of ownership.

When Buying Is the Smarter Move

• You’ll stay long enough to pass the break-even year.
• You want predictable housing costs instead of annual rent hikes.
• Building equity matters to you more than short-term flexibility.
• Rents are high relative to home prices where you live.
• You’re ready to maintain the place and make it your own.

How to Run Your Own Numbers

1. Get a real home price for the kind of place you’d actually buy.
2. Get a real rent for a comparable home — same size, same area.
3. Be honest about your timeline. This is the input that swings the answer most.
4. Use a realistic rate — the 2026 default is about 6.22%.
5. Set sensible assumptions for appreciation, rent increases, and investment return — then test a few to see how sensitive the answer is.

The goal isn’t a single magic number; it’s understanding which direction your situation leans and how confident you can be in it.
