A budget of €200,000, a stable job, and a five-to-ten-year time horizon: with these same parameters, buying a primary residence, investing in rental property, or continuing to rent can lead to very different financial outcomes. The choice depends less on personal preference than on balancing housing costs, net returns, and liquidity constraints.
The true cost of owning a property: expenses that online calculators overlook
Online comparison tools generally pit mortgage payments against rent. This approach is misleading. The true cost of ownership includes expenses that are rarely factored in: property tax, non-recoverable condominium fees, landlord insurance, a maintenance reserve, and notary fees spread over the ownership period.
In an older apartment building, condominium works (façade renovation, roof repairs, energy-efficiency upgrades) can amount to several thousand euros a year when averaged over ten years. Buyers who sell before the work cycle is complete bear the cost without benefiting from the associated increase in value.
There is also the opportunity cost of tying up your down payment. Notary fees, which amount to several percentage points of the purchase price for older properties, are an immediate sunk cost. For buying to become more advantageous than renting, the minimum ownership period is often more than five years, even in a stable market. In a declining market or a city with weak rental demand, that threshold is even higher.
We find that the most vulnerable cases are those where buyers underestimate the cost of repairs and maintenance. A condominium building from the 1970s with an E or F energy rating may require special assessments that were not included in the initial budget.
Net rental yield: balancing returns, vacancy, and taxes
Calculating gross yield by dividing annual rent by the purchase price is not enough to assess a rental investment. Net returns after expenses and taxes are the only meaningful measure, and they vary considerably depending on the tax regime chosen.
Several resources explain the tax rules that apply to rental income. Taxpayers looking to learn more can find useful information on real estate on Planet Argent, including how to weigh up unfurnished and furnished rentals.
With an unfurnished rental under the actual-expenses regime, deductible expenses (mortgage interest, repairs, property management, insurance) can create a rental deficit that can be offset against overall income, up to the limit set by the French General Tax Code. For furnished rentals, the actual-expenses BIC regime allows the property and furniture to be depreciated, reducing taxable income without requiring a cash outlay.
A common pitfall is choosing the micro-foncier or micro-BIC regime for simplicity, even when the actual-expenses regime would be more advantageous. For a property generating modest rental income, the difference can amount to several hundred euros in tax each year.
- Rental vacancy has a greater impact than a one-point increase in yield: one month without a tenant wipes out the benefit of charging slightly above-market rent.
- Property management fees typically amount to a few percentage points of rent collected, and should be included in your projections from the outset.
- Property tax, which is rising in many municipalities, eats into net returns year after year.
Buying a primary residence or renting and investing separately: a real-world example
Consider a typical buyer with a total budget of €200,000, available savings for a down payment, and a stable job—but who may need to relocate for work within three to five years. Two scenarios are possible.
Scenario A: buying a primary residence
The entire down payment and borrowing capacity are committed to the purchase. The owner no longer pays rent, but must cover notary fees, property tax, maintenance, and the risk of selling at a loss if they move sooner than expected. Wealth is almost entirely illiquid until the property is sold.
Scenario B: continuing to rent and investing the difference
The renter retains the freedom to move. The down payment that would have gone toward a home purchase can instead fund a rental property in an area with strong rental demand, or a diversified investment. Net rental income from the investment property can offset part of the rent paid.
Scenario B is more advantageous when the expected occupancy period is short (less than five years), the local market is stagnant, or the difference between rent and mortgage payments is small. Scenario A tends to win in a rising market, with a long occupancy period and a significant gap between rent and mortgage payments.
How to choose between buying, investing in rental property, and renting
The table below summarizes the key factors.
| Factor | Buying a primary residence | Rental investment | Renting |
|---|---|---|---|
| Suitable commitment period | More than 7 years | More than 10 years | Flexible |
| Wealth liquidity | Low | Low to moderate | High |
| Vacancy risk | None | Varies by area | None |
| Leverage through borrowing | Yes | Yes | No |
| Direct tax benefit | Limited | Rental deficit or BIC depreciation | None |
The expected ownership period remains the most decisive factor. Selling a home after three years almost always costs more than renting over the same period, due to notary fees and any early repayment penalties.
- If a work-related move is likely within five years, renting preserves your ability to invest elsewhere.
- If you plan to stay in an area with a stable job market, buying a primary residence can secure your housing costs over the long term.
- If building wealth is your main goal, investing in rental property in a high-demand area offers a better risk-return balance than buying a primary residence in an area with weaker demand.
The right choice is about more than comparing rent with mortgage payments. It also takes taxes, time horizon, repair risks, and your ability to cope with illiquidity into account. A tailored spreadsheet populated with real data from the local market remains the best tool for making the decision.
