Buying vs renting a home
It is one of the biggest financial decisions in life, and it is surrounded by clichés: "renting is throwing money away", "buying is always a good investment". Both are too simplistic. The real answer depends on the numbers and on your situation.
The false myth: "renting is throwing money away"
When you rent, you pay to use a home that does not tie up your capital or your life. When you buy with a mortgage, you also "throw away" money you do not get back: the mortgage interest, property tax, community fees, insurance, maintenance and purchase costs. The only things you "recover" are the capital repaid and the possible appreciation of the home. Comparing properly means putting all those costs side by side, not just "payment vs rent".
The key concept: opportunity cost
Opportunity cost is what you give up earning on money by using it for one thing instead of another. When you buy, you tie up a large down payment (plus purchase costs). That money, invested, could have earned a return. Any serious comparison must include it.
Example: a €40,000 down payment + €20,000 of costs = €60,000 tied up. If invested at 5 % a year, that is €3,000/year of opportunity cost that buying must "beat".
The buying costs people forget
Buying has costs that renting does not:
- Purchase costs (one-off): transfer tax (resale homes, varies by region, usually around 6-10 %) or 10 % VAT (new build), notary, registry, agency, appraisal.
- Recurring costs: property tax, community fees, home insurance, maintenance (rule of thumb: ~1 % of the property value per year), special levies.
- Mortgage interest: especially at the start (French system).
The costs of renting
- Monthly rent, which usually rises with inflation each year.
- Less stability: the contract may not be renewed; you might have to move.
- You build no wealth: you keep nothing at the end.
How to really compare
Don't just look at "payment vs rent". Compare the total cost over N years of each option, including in buying: down payment + costs + interest + property tax + community fees + maintenance − capital repaid − appreciation; and in renting: sum of rents + the opportunity cost of not having the down payment... but invested.
Factors favoring buying: you will stay for many years (purchase costs get diluted), the payment is similar to rent, you value stability. Factors favoring renting: job mobility, short horizon, very high purchase prices relative to rent, or you prefer to invest the down payment.
A shortcut: the price-to-rent ratio
For a first screen without building the whole spreadsheet, divide the purchase price by the annual rent of the same flat (or an equivalent one):
Ratio = purchase price / (monthly rent × 12)
- Below ~16: buying tends to pay off.
- Between 16 and 22: grey zone; the details decide (interest rate, how long you'll stay, expected appreciation).
- Above ~22-25: renting and investing the difference usually wins.
Example: a €250,000 flat that rents for €950/month → 250,000 ÷ 11,400 ≈ 21.9. Expensive to buy unless you stay for many years.
The mistake that skews every comparison
Comparing the mortgage payment with the rent alone, forgetting that renting frees you to invest the down payment. Put those €60,000 of down payment and fees into an index fund and they work for you while you rent. The honest comparison is buying versus renting and investing the difference, not versus renting and spending the rest.
