Investing in real estate has always been considered – rightly so, at least until a decade ago – one of the safest investments, synonymous with asset solidity, stability, and, except in rare and exceptional cases, an investment subject to appreciation: a house, over time, always appreciates.
The point lies in knowing how to manage it.
Real estate investment has a unique and specific peculiarity, differentiating it from other forms of investment, which is the generation of endemic costs that recur and grow over time: property taxes, municipal taxes, condominium fees (or equivalent in the case of single units), ordinary maintenance costs, and – increasingly unavoidable over time – extraordinary maintenance costs.
If you buy a property for investment and not for personal use, it needs to be rented with a remuneration sufficient to cover these costs and evidently leave a certain margin.
Otherwise, the observation is trivial, the investment is in loss.
