Why 'renting is throwing money away' is a misleading simplification
The argument that renting 'throws money away' compares the two options unfairly: it assumes buying has no equivalent cost, when it actually does, just a less visible one. The money you put toward a down payment (typically 20% of the price) stops being available to invest in another asset, and that opportunity cost never shows up on any monthly bill, but it's real.
On top of that, owning a home comes with expenses a renter doesn't pay directly: property tax, homeowners' association fees, home insurance, and maintenance and repairs, which over the long run typically run between 1% and 2% of the home's value per year. Comparing only 'mortgage payment' against 'monthly rent', without including these factors, is why the comparison usually ends up skewed in favor of buying.
The opportunity cost of the down payment and purchase costs
on a €250,000 home, the down payment plus purchase costs runs around €75,000-€80,000. If, instead of locking that amount into a down payment, you invested it in a global equity ETF with an expected 6% annual return, in 10 years that capital could grow to around €134,000, growth that simply doesn't happen when that money is tied up in a property.
This opportunity cost doesn't automatically mean renting is better: it means you need to compare it against what you gain from buying, which includes both the property's expected appreciation and the savings from not paying rent during those same years.
The break-even point: why how long you stay changes everything
The costs of buying (transfer tax or VAT, notary, land registry, legal fees) and of selling later (agency commission, local capital gains tax) easily add up to between 15% and 20% of the home's value across both transactions. That fixed cost gets spread across the years you live in the home: the longer you stay, the lower its annualized cost, and the sooner it's offset against continuing to rent.
As a general benchmark, buying tends to start paying off financially after around 7-10 years in the same home, though that figure varies with the local relationship between purchase price and rental price (the 'price-to-rent ratio'), which differs widely between cities and neighborhoods.
- Less than 3-5 years of expected residence: renting almost always comes out ahead financially.
- Between 5 and 7 years: it depends heavily on the local market and the gap between the mortgage payment and equivalent rent.
- More than 7-10 years: buying tends to pay off, except in markets with purchase prices heavily inflated relative to rent.
What renting does offer that buying doesn't: flexibility and liquidity
Renting has advantages that don't show up on any return-on-investment spreadsheet but matter just as much: the flexibility to move for a job or personal changes without a home sale's transaction costs, and keeping your savings liquid and diversified instead of concentrated in a single illiquid asset in a single location.
This is the same risk-concentration logic we cover in our chapter on home bias: buying a home in the same city where you work concentrates your wealth, your employment, and your daily life in the same geographic area, exactly the opposite of what a strict diversification principle would suggest.
How to decide in your specific case
The practical framework is to compare four things: how many years you plan to stay (the most decisive factor), the price-to-rent ratio in your specific area (if renting an equivalent home is much cheaper than the mortgage payment to buy it, the balance tips toward renting), your liquidity and job stability, and how much you subjectively value the stability and personalization of owning versus the flexibility of renting.
No calculator fully replaces this decision, but you can use our mortgage simulator to estimate your real monthly payment and honestly compare it against renting an equivalent home in the same area before deciding.

Frequently Asked Questions
Not exactly. Buying also has a cost, the opportunity cost of the locked-up down payment plus maintenance and transaction costs, which is simply less visible than a monthly rent bill.
As a general benchmark, after about 7-10 years, since the costs of buying and selling (between 15% and 20% of the home's value across both transactions) need to be spread across several years to offset continuing to rent.
It's the relationship between a home's purchase price and its equivalent annual rent in the same area. A high ratio signals that buying is relatively expensive compared to renting in that specific market, and vice versa.
It depends on the gap between that investment's expected return and the combined savings from appreciation and unpaid rent when buying. There's no universal answer: it depends on your time horizon and the local housing market.
It concentrates it. Buying in the same city where you work adds an illiquid, geographically concentrated asset to a net worth that already depends on that same area for your job, the opposite of what real diversification would suggest.
