Rent vs Buy Break-Even: How Many Years Until Buying Wins
Published 5 August 2026 · 9 min read · By the BecomeHH Team
There is no universal answer to "should I rent or buy" — but there is a universal mechanism. Buying a home starts you in a financial hole dug by transaction costs, and the question is simply how many years it takes to climb out. In Romania that hole is about 3.5% deep. In Spain it is 14%.
The most quoted rule of thumb is the five-year rule: own for at least five years or renting was probably the better call. It is a reasonable starting point — analyses consistently put the general break-even somewhere around five years — but it hides enormous variation. In high-cost coastal markets like San Francisco and New York, the break-even has stretched from three-to-five years to seven-to-ten as prices and rates rose. And the rule was built on American closing costs, which are among the lowest in the developed world.
If you are buying in continental Europe, the five-year rule is dangerously optimistic.
Why transaction costs decide almost everything
Buying and selling a home both cost money, and neither adds a cent to what the property is worth. Together they form a round-trip toll you pay for the privilege of owning.
- Buying costs — notary, legal, agent, registration and above all transfer tax. In the US this is roughly 2–5% of the price. In Spain, once ITP transfer tax is included, our data puts the typical resale round-trip at 14%.
- Selling costs — agent commission plus legal. In the US, 6–8% of the sale price; in much of Europe, 3–5%.
- The hole you start in — add them together and a US buyer is roughly 8–13% underwater on day one. A Spanish buyer can be closer to 17%.
None of that is recoverable. Before appreciation, before equity, before anything, the property has to gain that much value just to get you back to zero.
How long just to cover the transaction costs?
Below is the narrowest possible version of the question, which makes it the most useful floor. Ignore rent, ignore mortgage interest, ignore maintenance. Ask only: at a given rate of house-price growth, how many years until the property has appreciated enough to cover the round trip of buying and selling it?
Buying-cost data is BecomeHH's own researched notary + agent figure for each country. Selling costs are a conservative flat assumption you can change, because they vary far more by negotiation than by country.
Two things jump out. Romania, with the lowest round-trip costs in our dataset, clears the bar in a couple of years. Spain and France — with transfer taxes and notary scales among Europe's heaviest — need the better part of a decade at moderate growth, before a single other cost is counted.
And this is only the floor. Add mortgage interest, maintenance, property tax and the opportunity cost of your deposit, and the true break-even runs meaningfully longer than any of these numbers.
The table above is deliberately simplified. Our calculator does the complete version — your rent, your deposit, your rate, and the equity you would actually build.
Open the Rent vs Buy calculatorThe five inputs that move your break-even most
- Transfer tax in your country. The single biggest lever, and the one you cannot negotiate. See the full breakdown in our Hidden Buying Costs calculator.
- How long you will actually stay. Be honest rather than optimistic. Job changes, relationships and children move people more often than they expect.
- The gap between rent and the true cost of owning. Not rent versus mortgage payment — rent versus mortgage interest plus tax plus maintenance. Only the principal portion builds wealth.
- What your deposit would otherwise earn. A deposit sitting in a home is a deposit not compounding in an index fund. Our Invest vs Rent calculator puts a number on it.
- House-price growth — the one you cannot know. Treat any projection as a scenario, never a plan. If the case for buying only works at 5% annual growth, it is not a case, it is a bet.
When the five-year rule genuinely holds
It works reasonably well in low-transaction-cost markets with steady rent inflation — much of the US, the UK, Romania. It breaks down badly in three situations: high-transfer-tax markets (Spain, France, Belgium), markets where rents are unusually cheap relative to prices (Singapore, and much of China, where gross yields sit near 1.6%), and any market you might leave within three years.
The honest bottom line
Buying is not a good deal or a bad deal in the abstract. It is a good deal after year N, and N depends far more on your country's transfer tax and your own life plans than on anything happening in the housing market this quarter. Work out your N first. Then decide.
