Rent vs Buy in 2026: The Break-Even Math at 7% Mortgage Rates
At 7% mortgage rates on homes that haven't gotten cheaper, buying a comparable property costs 40–60% more per month than renting one in most major US metros. The question isn't whether renting is cheaper right now — it almost certainly is. The question is whether buying makes sense anyway when you run the full 10-year math.
- Monthly cost of ownership exceeds rent by 40–60% in most high-cost metros. The all-in cost — mortgage, taxes, insurance, maintenance — isn't close to renting right now.
- The break-even horizon has stretched to 8–12 years in expensive cities, up from 4–6 years in the 2015–2020 period. If you might move in under 7 years, renting wins on the math.
- The down payment opportunity cost is the number most calculators ignore. $400K invested in a diversified portfolio rather than used as a down payment generates meaningful expected returns.
- Buying can still make sense at 7% rates — with a long time horizon, meaningful expected appreciation, and a price-to-rent ratio below 20 in your market.
- This is not purely a financial decision. Stability, schools, the freedom to renovate, and control over your living situation have real value that doesn't appear in the spreadsheet.
Why This Moment Is Different From the Last Decade
From 2012 to 2021, buying a home in most markets made clear financial sense. Mortgage rates ranged from 3% to 4.5%, prices were recovering (not yet at their peaks), and the monthly cost of ownership in many markets approximated the cost of renting. Equity built quickly because the interest-to-principal ratio was manageable.
That environment is gone. Rates near 7%, combined with home prices that roughly doubled between 2019 and 2023 and have not materially corrected since, have created a cost-of-ownership environment that is genuinely unprecedented in the post-WWII era. The monthly payment on a median new 30-year mortgage in 2026 is roughly 2.3× what it was in 2021 on the same home — rates doubled while prices stayed elevated.
❌ "I'm paying $4,500/month in rent — that's just money down the drain. If I buy, at least I'm building equity."
🎯 Reality: At 7% on a $1.5M mortgage, your first monthly payment is approximately $9,980 — of which roughly $8,750 is interest. You are building $1,230 in equity per month while paying $8,750 in interest. Meanwhile, your rent is $4,500. The "equity building" argument only improves gradually over 30 years, and doesn't account for property taxes, maintenance, or the opportunity cost of your down payment.
The Real Cost of Ownership in 2026
Most mortgage calculators show principal and interest. That's approximately 60–70% of the true monthly cost of owning a home. Here's the full picture for a $1.8M home — typical for a senior tech or finance employee in a high-cost metro:
A comparable rental in the same metro for a similar property is typically $7,000–$9,500/month. The ownership premium — paying more per month to own than to rent — is roughly $4,500–$7,000/month. That's the "carrying cost of homeownership" — the money you're effectively paying each month for the option to build equity and the non-financial benefits of ownership.
On a $1.44M mortgage at 7%, annual mortgage interest in Year 1 is approximately $100,500. You can deduct mortgage interest on loans up to $750,000 — meaning $52,500 of your interest is deductible ($750K portion). At a 37% marginal rate, that's a tax saving of ~$19,400/year, or $1,617/month. This reduces your effective ownership cost — but the SALT deduction cap ($10,000) often means high earners in high-tax states can't fully utilize it alongside other itemized deductions. The deduction is real but smaller than most buyers assume.
The Break-Even Calculation
The break-even year is when cumulative wealth from buying equals cumulative wealth from renting-and-investing. It accounts for: equity built through principal paydown, home appreciation, the down payment opportunity cost, transaction costs on purchase and sale, and the monthly carrying cost differential.
Assumes 3–4% annual home appreciation, 6% alternative investment return, 6% transaction cost on sale. Individual results vary.
The Opportunity Cost Most Calculators Skip
When you put $400,000 into a down payment, that money is no longer compounding in a diversified portfolio. This "opportunity cost of capital" is one of the largest and most consistently ignored variables in the rent-vs-buy comparison.
The home itself must appreciate by more than this foregone return — net of transaction costs — for buying to win on pure wealth accumulation terms. In cities where home prices have already doubled and appreciation is expected to moderate, this hurdle is significant.
The Price-to-Rent Ratio: One Number to Know
The price-to-rent ratio (home price ÷ annual rent for a comparable property) is the fastest single signal for whether a market favors buying or renting. Below 15 historically favors buying; 15–20 is neutral; above 20 favors renting.
| Metro | Approx. Price/Rent Ratio | Signal |
|---|---|---|
| San Francisco | 34–42 | Rent |
| New York City | 28–36 | Rent |
| Los Angeles | 30–38 | Rent |
| Seattle | 25–32 | Rent |
| Boston | 24–30 | Rent |
| Miami | 22–28 | Rent |
| Austin / Denver | 18–24 | Neutral |
| Chicago / Atlanta | 14–20 | Neutral |
| Detroit / Cleveland / Memphis | 10–15 | Buy |

When Buying Still Makes Sense at 7%
The math above argues for renting in most high-cost metro scenarios. But the rent-vs-buy decision is not purely financial, and even financially, there are scenarios where buying wins.
Buy when you have a 10+ year horizon, a price-to-rent ratio below 22 in your market, and a down payment that doesn't materially deplete your liquid net worth. In every other scenario, the 2026 math favors renting — and deploying the down payment differential into a diversified portfolio.
The Non-Financial Reality
There are real, legitimate reasons to buy that don't appear in a spreadsheet. Stability for children in a school district. The freedom to renovate without a landlord's approval. Predictable housing costs over a 30-year fixed mortgage versus the uncertainty of lease renewals and rent increases. The psychological comfort of ownership and roots.
These are not irrational reasons to buy. They're just not financial reasons. The honest framing is: "I am willing to pay $X,000 more per month — and accept a longer break-even — in exchange for these non-financial benefits." Naming that cost explicitly is how you make a genuinely informed decision.
