Become someone who decides housing with numbers — not pressure
In 5 min you'll know: how to compare the total cost of renting vs buying over 10 years before you decide
In Block 1, Lesson 2, you mapped your month and discovered where each euro goes. Now imagine that your monthly map has a blot that consumes 40% or more of everything you earn: housing. The decision between renting and buying is probably the biggest financial choice of your life — and most people make it based on social pressure, not numbers. The rule: compare the total cost of renting vs. buying over 10 years before deciding.
Before you continue: in your monthly budget, how much do you spend on housing — and would that amount fit into a 30-year purchase plan?
(Answer in the next paragraph.)
Renting isn't money thrown in the bin. It's money that buys flexibility, liquidity and absence of market risk. When you rent, your monthly commitment is known (the rent), your exit cost is low (the contract lasts as long as it lasts) and you have no exposure to property-market fluctuations. The landlord bears the risk of maintenance, taxes and depreciation. In return, you don't build equity — rent is a consumption cost, not an investment.
Buying property isn't buying a house — it's buying a liability in the hope of appreciation. The mortgage repayment is just the start. There's (annual municipal property tax), paid annually based on the taxable property value. There's (one-off real-estate transfer tax), paid once at the deed and which can run into thousands of euros. There's the service charge, maintenance, mandatory insurance and, if you use credit, bank interest. In total, the cost of owning a home is typically 30-40% higher than the monthly repayment. And don't forget energy costs — (Portuguese energy regulator) oversees the market and (energy supplier of last resort) steps in if your commercial contract expires, so it's worth comparing tariffs before you move in.
The calculation nobody teaches you: if the repayment + IMI + service charge + maintenance exceeds the equivalent rent by more than 25%, you're paying a premium for ownership that may not pay off over 10 years — especially if you change city, job or life plans. Use concrete numbers: current rent vs. estimated repayment, available deposit, real debt-to-income ratio (not the one the bank calculates, which excludes living expenses). The decision isn't emotional — it's mathematical.
