After how many years does buying become profitable?

Generally, buying becomes profitable after 6 to 10 years of occupancy, depending on the city's price-to-rent ratio, the mortgage rate and notary fees (approximately 8% for existing properties). The longer the holding period, the more advantageous buying becomes thanks to the amortisation of fixed costs.

How do notary fees impact the comparison?

Notary fees (approximately 8% of the price for existing properties, 2-3% for new-builds) are an irrecoverable cost that weighs heavily in the early years. This is the main reason why buying is not profitable in the short term. It generally takes 5 to 8 years of ownership to amortise these fees.

Is rent really 'wasted' money?

No, rent is not wasted money. It provides you with housing and a flexibility that buying does not offer. Moreover, mortgage interest, notary fees, property tax and co-ownership charges are also non-recoverable expenses for an owner. The comparison must be comprehensive.

Which parameters have the greatest impact on the result?

The three most influential parameters are: the purchase price-to-annual rent ratio (the higher it is, the more renting is advantageous), the mortgage interest rate, and the annual property appreciation. Low appreciation or a high mortgage rate favour renting.

Buy or rent: key factors to consider

The decision between buying and renting your primary residence is one of the most important in personal finance. Contrary to popular belief, buying is not always the best financial option. Everything depends on the purchase price, the level of rents, mortgage rates, the expected duration of occupancy and property price trends.

The tenant has an often underestimated advantage: the ability to invest the down payment they did not use to buy. If the return on these savings exceeds the opportunity cost of renting, remaining a tenant can be financially more advantageous, especially in areas where purchase prices are very high relative to rents (price-to-rent ratio above 25).
