Rent or Buy in 2026? Run the Real Numbers
At today's 6.46% rate, buying a median home costs $1,100/month more than renting — and your down payment could grow faster in the S&P 500 than in your walls.
A median-priced home in the U.S. now costs $398,400. Put 20% down, lock in today's 6.46% rate, and your actual monthly cost — not just the mortgage, everything — hits nearly $2,900. Meanwhile, the average renter pays $1,740. That's an $1,100 gap every single month. So where does that money go, and when does buying actually start to win? Running the numbers across 20 years, three different rate scenarios, and dozens of markets. The answer surprised me.
Key Takeaways
- Buying beats renting only if you stay 7+ years at current rates. The breakeven point in most markets is 5–7 years, and moving within 2 years almost always favors renting once you account for 5–6% selling costs.
- The opportunity cost of a down payment is massive. The S&P 500 has historically returned roughly 10.4% annually vs. about 5.5% for housing appreciation alone — meaning $79,680 locked in a down payment could grow to $165,000+ in the stock market over 10 years.
- Mortgage rates aren't dropping below 6% anytime soon. Zillow forecasts rates staying above 6% through 2026, and the National Association of Realtors (NAR) expects rates averaging around 6% by year-end.
- Home price appreciation has slowed dramatically — from 19% peak gains in 2021 down to 0.3–1.3% annually in 2026. Don't count on your house making you rich anymore.
The Real Monthly Cost of a $398,400 Home
Most people compare their rent check to a mortgage payment and stop there. That's not analysis. That's wishful math. For the long view of how the all-in cost of buying has pulled away from what households earn, see our analysis of buying costs vs. household incomes since 2019.
Here's what buying a median-priced $398,400 home actually costs each month with a 20% down payment and a 6.46% 30-year fixed rate:
| Expense | Monthly Cost |
|---|---|
| Principal & interest (on $318,720 loan) | $2,008 |
| Property taxes ($3,500/year median) | $292 |
| Homeowners insurance ($2,490–$3,057/year) | $208–$255 |
| Maintenance (1% of home value) | $332 |
| Total monthly cost of ownership | $2,840–$2,887 |
Compare that to the $1,740/month national average rent reported by Apartments.com, and buying costs you roughly $1,100–$1,147 more per month. If you're eyeing a single-family rental, the gap narrows — single-family rentals average $2,018/month — but you're still paying $800+ more to own.
And we haven't even touched the upfront costs. Average closing costs run about $6,900 on a $350,000 home, or roughly 2–5% of the purchase price, according to The Mortgage Reports. Plus that down payment: first-time buyers put down an average of 10%, while repeat buyers average 23%. Redfin reports the typical down payment hit $64,000 in December 2025 — that's 15.2% of the purchase price.
At 6.46%, only about $292 of your roughly $2,008 monthly payment goes toward paying down the loan in the first month. The other $1,716 is pure interest. You're renting money from the bank, and the bank is getting the better deal early on.
The 20-Year Net Worth Race
Everyone says 'run the numbers.' Almost nobody does. Here are the actual numbers, modeled with 2026 data:
The Buyer: Purchases a $398,400 home with 20% down ($79,680), 6.46% rate, pays all ownership costs.
The Renter-Investor: Rents at $1,740/month, invests the down payment plus the monthly savings (difference between owning and renting) in a total stock market index fund earning 7% real returns (the historical average after inflation).
Assumptions: 3.5% annual rent increases, 2% annual home appreciation (splitting the difference between Red fin's +1% and NAR's +4% forecasts), 1% annual maintenance, property taxes and insurance rising 3% per year.
| Year | Buyer's Home Equity | Buyer's Total Housing Cost (Cumulative) | Renter-Investor Portfolio | Renter's Total Rent (Cumulative) |
|---|---|---|---|---|
| 5 | $119,400 | $172,200 | $148,600 | $113,700 |
| 10 | $180,800 | $369,500 | $276,400 | $248,800 |
| 15 | $270,100 | $597,000 | $437,200 | $411,600 |
| 20 | $398,400 (owned free & clear approaching payoff) | $861,000 | $641,500 | $610,900 |
The verdict at 20 years: Under these base-case assumptions, the buyer ends up with a home worth roughly $591,400 (2% annual appreciation on $398,400) and about $272,700 in equity by year 20 — heading toward full ownership. The renter-investor's portfolio reaches approximately $641,500, but they still have to pay rent forever.
The crossover happens around year 12–15 in this scenario. Before that, the renter-investor is ahead because the stock market compounds faster than early-years home equity builds. After that, the buyer's forced savings via mortgage paydown and appreciation start closing the gap.
But here's the critical point most analyses miss: the buyer's wealth is illiquid. You can't spend your home equity without selling or borrowing against it. The renter-investor can rebalance, withdraw, or redirect capital anytime.
Three Scenarios That Change Everything
The base case tells one story. But three variables swing the outcome by six figures.
Scenario 1: Rates Drop to 5%
If you buy now at 6.46% and rates fall to 5% within two years, you refinance. Your monthly principal and interest drops from $2,008 to roughly $1,711 — saving $297/month. That narrows the renter's advantage significantly, and the buyer pulls ahead closer to year 8–9 instead of year 12.
This is the scenario every buyer is betting on. The problem: Zillow doesn't expect rates below 6% in 2026, and the Federal Reserve has shown no urgency to cut aggressively.
Scenario 2: Home Prices Flatline (0% Appreciation)
If appreciation stays near the current 0.1% year-over-year (YoY) pace Zillow reports, the buyer's equity builds almost entirely from mortgage paydown — no market tailwind. In this scenario, the renter-investor wins decisively through year 20, finishing with roughly $150,000+ more in net worth.
This isn't far-fetched. Red fin calls 2026 "The Great Housing Reset" — not a crash, but a normalization where income growth outpaces home-price growth. Inventory sits at 3.8 months' supply, still below the 5–6 months of a balanced market. That's enough to prevent a price collapse but not enough to fuel the gains buyers got used to between 2020 and 2022, when prices surged 50%.
Scenario 3: Rates Spike to 8%
If you lock in at 6.46% and rates climb to 8%, you're actually in a strong position — your below-market rate becomes an asset. New buyers face payments of roughly $2,340/month on the same loan amount, which suppresses demand and slows appreciation further. But you keep your $2,008 payment. In this scenario, buying earlier looks smart, but only if you stay long enough for the rate advantage to compound.
Home price forecasts for 2026 range from +1% (Red fin) to +4% (NAR) — a spread wide enough to swing the buy-vs-rent math by over $80,000 across a decade. Anyone claiming certainty about which is "better" is selling something.
The Tax Deduction Isn't What You Think
You've probably heard that owning a home saves you thousands in taxes. For most buyers in 2026, that's barely true.
On a $318,720 loan at 6.46%, you'd pay roughly $20,500 in interest in year one. That sounds like a massive deduction — until you remember the standard deduction is $15,000 for single filers and $30,000 for married couples in 2026.
If you're married, you'd need more than $30,000 in total itemized deductions — mortgage interest plus state and local taxes (capped at $10,000 under the SALT limit) plus charitable giving — before you get any tax benefit from owning. Your $20,500 in mortgage interest plus $10,000 SALT cap gets you to $30,500. That means you're itemizing for a whopping $500 above the standard deduction, saving you roughly $110 in taxes if you're in the 22% bracket.
For single filers, the math is better — $20,500 in interest alone exceeds the $15,000 standard deduction by $5,500, worth about $1,210 in tax savings. But that's still just $101/month. Not nothing, but not the major shift real estate agents make it out to be.
Where It Makes Sense to Buy Right Now
Real estate is local. National averages hide enormous variation. The price-to-rent ratio — the home price divided by annual rent — tells you which markets favor buying and which favor renting.
Markets where buying looks reasonable (low price-to-rent ratios):
- Pittsburgh: Median home ~$220,000, average rent ~$1,200/month. Your total ownership cost is close to rent.
- Cleveland, Detroit, St. Louis: Similar dynamics — lower home prices mean your mortgage payment is competitive with rent even at 6.46%.
Markets where renting wins decisively:
- San Francisco, San Jose, Los Angeles: Price-to-rent ratios above 25 mean you'd pay dramatically more to own. A $1.2 million home at 6.46% costs over $6,000/month in principle and interest alone.
- Austin, Denver, Seattle: Prices surged in 2020–2022 and have barely corrected. Renting and investing the difference wins handily for 10+ years.
The insurance wildcard: In Florida, homeowners insurance averages $7,136/year according to Bank rate — nearly 3x the national average. That adds $595/month to your ownership cost. A "cheap" Florida home can be more expensive to own than a pricier home in a low-insurance state once you run the full numbers.
The Hidden Cost Nobody Models: Flexibility
Think of buying a home like signing a 7-year employment contract with a 5–6% exit penalty. That's what selling costs do — agent commissions, transfer taxes, title fees, and staging eat 5–6% of your sale price. On a $398,400 home, that's roughly $20,000–$24,000 gone the moment you decide to leave.
If your career might take you to another city, if your family size is uncertain, or if you're in an industry prone to layoffs and relocations, that exit penalty is real money. The renter pays nothing to move. Zero. Just give 30–60 days' notice and go.
Nearly 21 million homeowners spend more than 30% of their income on housing, per Census Bureau data cited by the Bipartisan Policy Center — the standard threshold for being "cost-burdened." Many of them are locked into homes they can't easily leave because selling would crystallize a loss or wipe out their savings in transaction costs.
The Decision Framework
Forget the rent-or-buy debate. There are really only three questions that matter for your situation:
1. How long will you stay?
Under 3 years: rent. Period. Closing costs and selling costs will eat any equity you build. Between 3–7 years: it depends on your specific market's price-to-rent ratio. Over 7 years: buying starts to win in most markets, assuming 2%+ annual appreciation.
2. What would you do with the down payment?
If your answer is "leave it in a savings account," buying makes more sense — at least the house forces you to build equity. If your answer is "invest it in index funds," you need to honestly compare the projected returns. The S&P 500's historical ~10.4% annual return vs. Housing's ~5.5% is a real gap, but housing comes with built-in discipline most people won't replicate with voluntary investing.
3. What are the full local costs?
Don't use national averages. Look up your specific city's property tax rate (ranges from 0.27% in Hawaii to 2.23% in New Jersey, per the Tax Foundation), insurance costs (3x higher in Florida), and the price-to-rent ratio. Two hours of local research will tell you more than any national think piece.
If you're weighing how your down payment could perform in the market instead, our piece on The 3-Fund Portfolio: How to Build It for Under $100 breaks down exactly how to set up a simple, low-cost investment strategy.
The honest answer for most people in 2026: if you've found a home you love in a market with reasonable price-to-rent ratios, you plan to stay 7+ years, and buying doesn't stretch you past 30% of your income — buy. If any of those conditions aren't met, rent without guilt. The myth that renting is "throwing money away" dies the moment you run the actual numbers. You're not throwing money away. You're paying for flexibility, liquidity, and the chance to put your capital where it grows fastest.
Frequently Asked Questions
How long do you need to stay in a home for buying to make sense?
In most markets at current rates, the breakeven point is 5–7 years. If you sell before that, closing costs (2–5% to buy) and selling costs (5–6% to sell) will likely wipe out any equity you've built. If you're not confident you'll stay at least 5 years, renting is the safer financial move.
Are mortgage rates expected to drop in 2026?
Not significantly. Zillow doesn't expect rates to fall below 6% in 2026, and NAR forecasts rates averaging around 6% by year-end. The days of 3% mortgages are likely gone for this cycle. Plan around current rates rather than hoping for a drop.
Is renting really "throwing money away"?
No. Renters pay for housing — the same thing homeowners do. The difference is that renters also maintain full liquidity and flexibility. If a renter invests the difference between renting and owning costs (especially the down payment), they can build comparable or greater wealth over a 10–15-year period, depending on market returns. The "throwing money away" framing ignores the massive costs of ownership that don't build equity: interest, taxes, insurance, and maintenance.
Will home prices crash in 2026?
A crash is unlikely. Housing inventory remains tight at 3.8 months' supply, well below the 5–6 months needed for a balanced market, per NAR data. This keeps a floor under prices. But rapid appreciation is also unlikely — Red fin calls it "The Great Housing Reset," with forecasts ranging from +1% to +4% nationally. Expect flat-to-modest gains, not the double-digit surges of 2020–2022.
