Rent vs Buy: The Break-Even Year Nobody Tells You About
A friend of mine ran the numbers on a $410,000 house last spring, at a 6.75% mortgage rate. Her monthly principal and interest alone came out higher than the $2,300 she was paying in rent for a two-bedroom a mile away. Her parents told her renting was "throwing money away." Her spreadsheet told her something different: at that rate, in that market, she'd need to stay in the house for almost eight years before buying actually came out ahead of renting and investing the difference.
That gap — between what everyone assumes about renting versus buying and what the math actually says once mortgage rates sit above 6% — is the whole reason this decision is worth running through a calculator instead of a gut feeling. This article walks through how to find your own break-even point, using a real worked example in US dollars and one in British pounds, so you can see whether "buy as soon as you can" still holds up in 2026.

What Is the Rent vs Buy Break-Even Point?
The rent vs buy break-even point is the number of years you'd need to own a home before your total cost of ownership drops below the total cost of renting the equivalent property, once closing costs, ongoing maintenance, and the opportunity cost of your down payment are all counted. Below that year, renting comes out cheaper in pure dollar terms — even though you're not building equity. Above it, ownership pulls ahead.
The mistake almost everyone makes is comparing a single number: this month's mortgage payment against this month's rent. That comparison ignores the roughly 2–5% of the purchase price you pay upfront in closing costs, the 1–2% of home value you'll spend on maintenance every year, and the fact that a down payment sitting in a house isn't earning a return anywhere else. A proper comparison has to run over years, not months.
Key Takeaway
Comparing "mortgage payment" to "rent payment" is not a rent vs buy comparison — it's comparing two different products. A real comparison needs a time horizon, because buying has high upfront costs that only pay off if you stay long enough to spread them out.
A Worked Example: $410,000 House vs $2,300 Rent
Here's my friend's numbers, worked in full. She had $82,000 saved for a 20% down payment, and was comparing a $410,000 house against a $2,300/month rental in the same neighbourhood.
| Line item | Buying | Renting |
|---|---|---|
| Upfront cost | $12,300 (3% closing costs) | $4,600 (2 months' deposit) |
| Monthly payment | $2,128 (P&I at 6.75%, 30yr) | $2,300 |
| Property tax + insurance | $410/month | — |
| Maintenance reserve (1%/yr) | $342/month | — |
| Total monthly cash cost | $2,880 | $2,300 |
On the cash-cost line alone, renting was already $580 a month cheaper. That gap gets partly offset by two things buying provides that renting doesn't: principal paydown, which is forced savings, and appreciation, which is not guaranteed. In year one, roughly $410 of her $2,128 mortgage payment went to principal rather than interest — money she keeps as equity, not an expense. Once you net that back out and add a conservative 3% annual appreciation assumption, her real "net cost" of owning fell to about $2,150 a month by year three, still slightly above her rent but closing the gap each year as the loan amortises further.
The Riverside, California-based mortgage data firm HSH.com has tracked the rent vs buy gap for over a decade, and its research consistently shows the break-even point in most major US metros lands somewhere between 3 and 8 years, depending heavily on local rent growth and the mortgage rate at purchase. Run your own numbers through the Rent vs Buy Calculator rather than borrowing someone else's — an 8-year break-even at a 6.75% rate can become a 4-year break-even at 5%, so the rate you actually lock matters as much as the house price.
In the UK, the comparison runs the same way with different inputs: a £320,000 flat with a 10% deposit at 5.2% (a typical 2026 two-year fixed rate) against £1,450/month rent for an equivalent flat produces a similar shape — a monthly cash cost roughly £280 above rent in year one, closing to near parity by year five once Stamp Duty and legal fees are amortised and principal paydown accelerates.
The Ownership Costs Renters Never See
The line items that get left out of casual rent-vs-buy conversations are almost always on the buying side, because they don't show up on a mortgage statement.
- Closing costs: Typically 2–5% of the purchase price in the US (lender fees, title insurance, appraisal, recording fees) and 1–7% in the UK once Stamp Duty Land Tax is included on higher-value properties. These are sunk the day you buy — they don't build equity.
- Maintenance and repairs: The US National Association of Realtors and most mortgage lenders use a 1–2% of home value per year rule of thumb for maintenance — on a $410,000 house, that's $4,100–$8,200 annually, or roughly $340–$680 a month, that a renter's landlord absorbs instead.
- HOA or service charge fees: Common on condos and flats, and easy to forget when comparing a mortgage quote to a rent listing that doesn't have one.
- Selling costs: When you eventually sell, US real estate agent commissions typically run 5–6% of the sale price. If you might move again within a few years, that cost erodes any equity gain fast.
⚠️ Note
If you might relocate for a job within 2–3 years, factor in the roughly 8–11% of the sale price you'll lose to buying and selling costs combined. That alone can erase several years of equity gains, which is why short time horizons usually favour renting regardless of the monthly payment comparison.
Why the Down Payment's Opportunity Cost Matters
This is the piece that gets skipped most often, and it's the one that swings the answer the most. My friend's $82,000 down payment wasn't free money sitting in a drawer — it was capital that could have stayed invested. Had she kept renting and invested that $82,000 in a diversified index fund instead, at a historically reasonable long-run average return of around 7% after inflation, it would have grown to roughly $115,000 over five years, untouched.
💡 Pro Tip
Don't just compare home appreciation to nothing — compare it to what your down payment would have earned invested elsewhere. If your local housing market historically appreciates around 3–4% a year and a simple index fund has historically returned closer to 7%, that gap is a real cost of tying up capital in a house, even before counting maintenance.
This doesn't mean renting always wins — home equity is also a forced, disciplined form of saving that many people wouldn't otherwise stick to, and mortgage leverage means gains on the full home value accrue to you even though you only put down 20%. But pretending the down payment has zero opportunity cost is exactly how "buying is always better long-term" claims get overstated.
When Does Renting Actually Win?
Renting tends to come out ahead of buying, on pure cost terms, in a few recurring situations:
- Short time horizons. If you expect to move within 2–4 years, transaction costs on both ends rarely have time to amortise.
- High price-to-rent markets. Coastal US cities and parts of London and Sydney often carry price-to-rent ratios above 25, meaning it would take 25+ years of rent to equal the purchase price — a strong signal that renting is capital-efficient there even if buying feels "safer."
- Elevated mortgage rates relative to rent growth. When mortgage rates run well above the local rate of rent inflation, as much of the US and UK experienced through 2023–2026, the extra interest cost of financing often outpaces what you'd save by locking in a "fixed" housing cost.
- Uncertain job or life situation. Renting keeps you mobile. That flexibility has a real, if hard-to-price, value that a break-even spreadsheet can't fully capture.
| Scenario | Renting typically wins | Buying typically wins |
|---|---|---|
| Time horizon | Under 3–4 years | 7+ years |
| Local price-to-rent ratio | Above ~20 | Below ~15 |
| Mortgage rate vs rent growth | Rate well above rent inflation | Rate near or below rent inflation |
| Job/life stability | Uncertain, may relocate | Settled, long-term plans |
Frequently Asked Questions
Is renting really "throwing money away"?
Not in a strict financial sense. Rent buys housing services for a month, the same way a mortgage payment buys a mix of interest, principal, tax, insurance, and maintenance. The part of a mortgage payment that goes to interest, tax, insurance, and maintenance is just as "gone" as rent — only the principal portion builds equity, and in the early years of a 30-year loan that's typically a minority of the payment.
How long should I plan to stay before buying makes sense?
Most US market analyses put the typical break-even point somewhere between 3 and 8 years, but it depends heavily on your mortgage rate, local rent growth, and closing costs. A rough industry rule of thumb is 5 years as a minimum, though the only reliable number is the one you calculate from your own local rent and purchase price using a rent vs buy calculator.
Does a bigger down payment always make buying better?
Not automatically. A larger down payment reduces your monthly mortgage payment and can eliminate private mortgage insurance in the US, but it also ties up more capital that could otherwise be invested. The right down payment size depends on your mortgage rate versus your expected investment returns, not just on minimising the monthly payment.
Should I include home appreciation in the comparison?
Yes, but conservatively. Long-run US home price appreciation has averaged roughly 3–4% annually over multi-decade periods according to Case-Shiller index data, though any individual market or decade can run well above or below that. Using an aggressive appreciation assumption to justify a purchase is the same mistake as ignoring appreciation entirely — both distort the real comparison.
What's the single input that changes the break-even point the most?
The mortgage interest rate. A 1.5 percentage point difference in rate on a $400,000 loan changes the monthly interest cost by several hundred dollars, which can shift a break-even point by 2–3 years in either direction. It's worth re-running the numbers any time your quoted rate changes, even by a small amount.
Try It Yourself
The right answer to "rent or buy" isn't a rule of thumb — it's a break-even year, and it's different for every combination of price, rate, rent, and how long you plan to stay. Run your own numbers, including maintenance and the opportunity cost of your down payment, before deciding either option is obviously smarter.
