Rent vs. buy, the honest comparison
Most rent-vs-buy framing quietly favors buying, by understating ownership costs and assuming the rent-side savings just disappear. The honest version models full ownership cost, the investment alternative on the down payment, and shows the breakeven year explicitly.
On a $500K home with 20% down at 7%, the buyer’s liquid wealth from selling overtakes the renter’s investment account at year beyond the horizon assuming 3% appreciation and a 7% investment return on the down payment.
Buyer asset position (brass) is sale-proceeds-net at year y — the cash a seller would walk away with after commissions, costs, and remaining loan. Renter asset position (ink) is the investment account balance from depositing the down payment plus closing costs at year zero, and then year-by-year contributing whatever the buyer spent above the renter’s rent. Both households commit the same gross cash; the chart compares who has more if they liquidate at year y.

Key takeaways
- The honest comparison is buying-cost-of-ownership (interest, taxes, insurance, maintenance, opportunity cost on the down payment) against rent plus investment returns on what would have been the down payment.
- Breakeven typically lands at 5–7 years of ownership at long-term average appreciation, longer in slow-growth markets.
- Transaction costs (closing costs on the way in, plus 6–8% selling costs on the way out) are the single largest cost to recoup, so short-tenure buys rarely come out ahead.
- The 5% rule (annual cost of owning approximately 5% of home value, split as 1% maintenance, 1% taxes, 3% capital cost) is a quick mental check, though it varies materially by region.
Quick answers
- Is it better to rent or buy a home?
- It depends on how long the buyer plans to stay, local price-to-rent ratios, expected home appreciation, the alternative investment return on the down payment, and rent inflation. The honest comparison models all of these and produces a breakeven year, the year buying overtakes renting on after-tax wealth.
- How long do I need to stay in a home for buying to make sense?
- Typical breakeven horizons run 4–7 years depending on the market. Shorter horizons usually favor renting because closing costs (2–5% of purchase price) and selling costs (5–7% of sale price) eat the small accumulated equity gain. Longer horizons (7+ years) usually favor buying assuming reasonable appreciation.
- What costs do most rent-vs-buy comparisons miss?
- Most comparisons understate ownership costs by omitting maintenance (1–3% of home value annually), property tax growth as the home appreciates, insurance inflation, HOA increases, and selling costs at exit. They also commonly assume the rent-side cash savings disappear instead of being invested at a market return.
Buying a home tends to win financially over long holding periods (typically seven years or more) in markets with reasonable appreciation; renting tends to win over short horizons or in markets where investment returns on the down payment dominate. The honest comparison models full ownership cost (mortgage, taxes, insurance, maintenance, transaction costs) against the investment alternative on the down payment, and shows the breakeven year explicitly rather than picking a winner. The breakeven is highly sensitive to assumptions that nobody can predict accurately in advance, which is why running scenarios produces a more honest read than any single number.
The question gets framed in two unhelpful ways. The first is the bumper-sticker version ("renting is throwing money away"), which ignores what a renter who invests the difference ends up with. The second is the over-rationalist version ("it's purely a financial calculation"), which ignores why people buy houses in the first place.
The rent-vs-buy calculator at /tools/rent-vs-buy runs the year-by-year simulation. This article is the framing for what the calculator is actually computing.
What the buy side actually costs
The recurring costs people remember are principal and interest, property tax, homeowners insurance, HOA where applicable, and PMI when the down payment is under 20%. Those are the line items that show up on every rate sheet.
The recurring costs people often understate are bigger. Maintenance, conventionally estimated at 1–2% of home value per year averaged over time, lumps unevenly across specific years, some years it's zero, some years it's a $14,000 roof or a $9,000 HVAC replacement. The annual average is real even when the cash flow isn't smooth. Major systems run on long cycles: HVAC has a 15–25 year life, roof 20–30 years, water heater 8–15. A 30-year ownership typically intersects at least one full replacement cycle on each. Property tax growth is the third underrated line. Most jurisdictions reassess on appreciation, with the exceptions of California's Prop 13 (capping at 2% annually) and Florida's Save Our Homes (lesser of 3% or CPI). In fast-appreciating markets without a cap, property tax growth can outpace wages.
Then there are the one-time costs: down payment, closing costs (typically 2–5% of home price), and the moving and immediate repair-and-paint costs that almost always materialize.
What the rent side actually costs
The recurring rent payment, plus renters insurance (a few hundred dollars a year, almost trivial), plus rent inflation. A 3% annual rent increase, sustained over 10 years, is a 34% rent increase.
The thing the rent side often gets credit for, which the bumper-sticker version ignores: the down payment and closing costs the renter didn't spend on a house can be invested instead. At a 7% real long-run return, a $90,000 initial investment becomes $177,000 in 10 years and $349,000 in 20. That's not theoretical; it's the comparison the rent-side number is built against in the calculator.
How the comparison actually works
Both households commit the same gross cash flow to housing-and-savings. The buyer pays it all to the home (PITI + maintenance + HOA, net of any tax savings). The renter pays rent and routes the surplus to (or shortfall from) an investment account. At the end of the time horizon, both households liquidate: the buyer sells the home, the renter cashes out the investment account. The breakeven year is the first year the buyer's sale-proceeds-net exceeds the renter's investment account balance.
This framing matters. Most rent-vs-buy calculators online quietly compare the buyer's wealth change (sale proceeds minus total cash spent) to the renter's investment account balance, which double-counts the cash spent against the buyer. The honest version compares like to like, sale proceeds against investment balance, both representing the cash position at end of horizon if the household liquidated.
Under the honest framing, in a typical scenario ($400k home, 7% mortgage rate, 3% appreciation, 7% investment return, $2,500/month rent, 7-year horizon, no PMI), buying tends to overtake renting somewhere in years 4–7. Aggressive appreciation pulls that crossover earlier. Strong investment returns push it later. Short horizons (under 4 years) almost always favor renting because closing costs and selling costs eat the small accumulated wealth difference.
What the comparison doesn't capture
The financial answer is one input. The decision is bigger.
Owners get stability and control. They can repaint, renovate, plant a tree, stay put for 30 years. Renters trade that for flexibility, someone can leave for a job in another city in 60 days, where an owner typically needs 3–6 months to sell with material transaction costs along the way. The forced-savings effect is real on the buy side, since paying down a mortgage builds equity automatically; investing the rent-side difference requires actual discipline that not everyone has. The calculator silently assumes the discipline; reality often doesn't deliver it. There's also the harder-to-measure stuff. Homeowners tend to know their neighbors better and stay longer in the same place, which has real but unmeasured value. Homeownership is also a non-trivial labor commitment, and some people genuinely enjoy that and some genuinely don't.
None of this shows up in the calculator. It should still show up in the decision.
A useful summary
If you'll be in the same place for 7+ years, in a market with reasonable appreciation, and you'll either invest the renting difference or skip the investment-and-buy comparison entirely (because you'll never invest it), buying usually wins financially. If you'll be there for 3 years or less, renting almost always wins. The middle case (4–6 years) is where the assumptions matter, and the assumptions are exactly what nobody can predict precisely. The honest position is to model your own scenario, look at the sensitivities, and accept that the financial answer is one consideration in a decision that also involves stability, flexibility, and what kind of life you're trying to build.
Frequently asked
Is it better to rent or buy a home?
It depends on how long the buyer plans to stay, local price-to-rent ratios, expected home appreciation, the alternative investment return on the down payment, and rent inflation. The honest comparison models all of these and produces a breakeven year, the year buying overtakes renting on after-tax wealth.How long do I need to stay in a home for buying to make sense?
Typical breakeven horizons run 4–7 years depending on the market. Shorter horizons usually favor renting because closing costs (2–5% of purchase price) and selling costs (5–7% of sale price) eat the small accumulated equity gain. Longer horizons (7+ years) usually favor buying assuming reasonable appreciation.What costs do most rent-vs-buy comparisons miss?
Most comparisons understate ownership costs by omitting maintenance (1–3% of home value annually), property tax growth as the home appreciates, insurance inflation, HOA increases, and selling costs at exit. They also commonly assume the rent-side cash savings disappear instead of being invested at a market return.Does buying make sense with a low down payment?
With less than 20% down, conventional loans carry PMI and FHA loans carry MIP, both of which raise the monthly carrying cost. Lower down payments also leave less equity cushion if home values dip. Buying can still make sense with a low down payment, but the math is closer than at 20% down.Why do rent-vs-buy calculators give different answers?
Different calculators make different assumptions about appreciation rate, investment return on the alternative capital, maintenance percentage, tax-deduction availability, and selling costs. The conclusions can swing thousands of dollars per year based on which assumptions are used, which is why running scenarios (not just one calculation) produces a more honest read.
