Is It Cheaper to Rent or Buy a House? The Unrecoverable Cost Method
Short answer
Renting is cheaper than buying in the first years in most markets because owners pay interest, tax, upkeep and large one-off transaction costs. Buying often becomes cheaper per month by year ten as rent rises and the mortgage stays flat. Whether buying is cheaper overall depends on whether those later savings outweigh the buying and selling costs within your stay.
Key takeaways
- Compare unrecoverable costs: rent versus interest, property tax, insurance, upkeep, lost investment returns and transaction costs, minus expected appreciation.
- On a monthly basis, buying is often close to rent in month one and cheaper by year ten.
- One-off buying and selling costs are what usually make renting cheaper over shorter stays.
- In Germany, buying is cheaper per month at our defaults, but roughly €61,000 of transaction costs keeps renting ahead over 10 years.
Is it cheaper to rent or buy a house?
In most markets, renting is cheaper than buying for the first several years, because owners pay large one-off buying and selling costs on top of interest, property tax, insurance and maintenance. Buying often becomes cheaper per month later, as rent rises while a fixed mortgage payment does not. Whether buying is cheaper overall depends on whether those later monthly savings outweigh the transaction costs before you move.
The trick is to compare the right costs. This guide uses the unrecoverable cost method, then shows how the comparison changes between month one and year ten using our calculator’s late-2026 default figures.
What are unrecoverable costs?
An unrecoverable cost is money you spend on housing that you never get back. It is the fair basis for asking whether renting is cheaper than buying, because it removes the part of a mortgage payment that is really saving (the principal) and includes the costs that never appear in the payment.
| Renter’s unrecoverable costs | Owner’s unrecoverable costs |
|---|---|
| Rent | Mortgage interest |
| Renter’s insurance and fees | Property tax |
| Home insurance | |
| Maintenance and repairs | |
| Strata, HOA or service charges | |
| Opportunity cost of the money in the home | |
| Buying costs (one-off) | |
| Selling costs (one-off) | |
| Minus expected price growth |
The opportunity cost is the return the deposit (and later the equity) would have earned if it had been invested instead. The expected price growth is the owner’s offset: it is the return on the home itself. Ben Felix’s 5% rule is a shortcut version of this same framework.
Month 1: is buying a house cheaper than renting at the start?
Here is the first month for a typical US home using our default assumptions: a US$420,000 home, 20% down, a 6.3% 30-year mortgage, 1.1% property tax, 1% maintenance, 0.55% insurance, a 7% investment return and 3.5% annual price growth.
| Month 1, United States | Amount |
|---|---|
| Mortgage interest | US$1,764 |
| Property tax | US$385 |
| Maintenance | US$350 |
| Home insurance | US$193 |
| Cash unrecoverable costs | US$2,692 |
| Opportunity cost of US$96,600 deposit and buying costs | +US$564 |
| Expected price growth on US$420,000 | −US$1,225 |
| Net economic cost of owning | ~US$2,030 |
| Rent plus renter’s insurance | US$2,115 |
On a pure cash basis, the owner’s unrecoverable costs (US$2,692) are well above rent. Once you credit expected price growth and charge for the lost investment return, owning costs about US$2,030 a month, slightly below rent. So why does our calculator still show the renter ahead after ten years? The answer is the one-off costs, which we come to below.
Year 10: how the monthly comparison shifts
Ten years later, three things have changed. Rent has grown at 3.5% a year. The interest portion of the mortgage has fallen as the balance shrinks. But the owner’s equity has grown, so the opportunity cost of that equity is larger, and the costs tied to the home’s value have risen with it.
| Month 120 | United States | United Kingdom | Canada | Germany |
|---|---|---|---|---|
| Mortgage interest | US$1,491 | £677 | C$1,492 | €842 |
| Tax, insurance, upkeep | US$1,305 | £373 | C$1,564 | €593 |
| Opportunity cost of equity | US$1,789 | £999 | C$2,878 | €1,336 |
| Expected price growth | −US$1,723 | −£972 | −C$2,346 | −€913 |
| Net cost of owning | ~US$2,860 | ~£1,080 | ~C$3,590 | ~€1,860 |
| Rent (incl. renter costs) | ~US$2,880 | ~£1,930 | ~C$3,160 | ~€1,970 |
By year ten, owning is roughly level with renting in the US, far cheaper in the UK, cheaper in Germany and still more expensive in Canada. Canada stays expensive because its default rent (C$2,300 on a C$700,000 home) is low relative to the price, and a large, growing pile of equity earns 3% in the house instead of 6.5% in a portfolio.
The one-off costs that change the answer
Monthly comparisons leave out the two biggest single payments in owning: buying costs and selling costs. Over ten years with our defaults:
| Market | Buying costs | Selling costs (on year-10 price) | Total one-off |
|---|---|---|---|
| United States | US$12,600 (3%) | ~US$35,500 (6%) | ~US$48,100 |
| United Kingdom | £7,250 (2.5%) | ~£7,800 (2%) | ~£15,000 |
| Canada | C$17,500 (2.5%) | ~C$47,000 (5%) | ~C$64,500 |
| Germany | €45,000 (10%) | ~€16,500 (3%) | ~€61,500 |
Germany is the clearest example of why the monthly view misleads. Buying is cheaper per month in both month one and year ten at our defaults, yet renting still leaves you about €65,000 ahead after ten years. Kaufnebenkosten (transfer tax, notary, land registry and broker fees, commonly 9–12%) take years of small monthly savings to recover. The US is similar: monthly costs are close, but nearly US$48,000 of transaction costs tip the 10-year result to renting by about US$42,000.
In the UK, low one-off costs (a first-time buyer pays no Stamp Duty Land Tax below £300,000, according to GOV.UK) combined with high rent relative to price make buying cheaper within about two years.
Cheaper to rent or buy? A quick verdict by market
Using the full simulation, which combines monthly costs, one-off costs and investment of any difference, our late-2026 defaults show this over ten years:
| Cheaper to buy | Close | Cheaper to rent |
|---|---|---|
| UK, Ireland, Dubai, Singapore, London, Spain | Australia, US, New Zealand, France | Canada, Toronto, Germany, India, New York, Sydney |
The “close” group is where your own figures matter most. Small changes in rent, rate or price growth can flip them.
How to work out whether renting is cheaper for you
- Total the owner’s cash unrecoverable costs for one month: interest (balance × rate ÷ 12), property tax, insurance, maintenance and any service charge.
- Add the opportunity cost: deposit plus buying costs × your expected after-tax return ÷ 12.
- Subtract expected price growth: home value × a cautious growth rate ÷ 12.
- Compare with rent plus renter costs. This is your month-one picture.
- Spread the one-off costs: add buying costs and estimated selling costs, then divide by the number of months you plan to stay. Add that to the owner’s monthly figure.
- Check the long run with the rent vs buy calculator, which repeats this month by month, grows rent and costs each year, and invests whichever side has spare cash.
Step 5 is where short stays fall apart. US$48,000 of one-off costs is about US$400 a month over ten years, but roughly US$1,300 a month over three.
Is renting cheaper than buying for a short stay?
Almost always. The shorter the stay, the fewer months there are to absorb the one-off costs, and the less time rent growth has to work in the owner’s favour. Our calculator expresses this as a break-even rent for each horizon. For the US default home, renting is cheaper over three years unless comparable rent is above about US$3,040 a month, nearly 45% more than the default rent. Over five years the threshold is about US$2,620; over ten, about US$2,310.
Even in markets where buying wins over ten years, the first year or two usually favour the renter. With our defaults, the buyer is still behind after one year in the UK (by about £5,000), Dubai (about AED 92,000) and Spain (about €34,000). Only Ireland, with a 10% deposit, low buying costs and 5% assumed price growth, shows buying ahead within the first year. If there is a real chance you will move within three years, treat renting as the cheaper option unless the numbers are overwhelming.
When is buying a house cheaper than renting?
Buying tends to be cheaper when:
- Rent is high relative to price, roughly 5.5% or more of the price per year, and recurring owner costs such as property tax are modest.
- One-off transaction costs are low, under about 5% for the round trip.
- Your mortgage rate is at or below your expected investment return.
- You stay long enough for rent growth to work in your favour.
And renting is cheaper when the opposite holds, particularly when you might move within five years.
