Buying a home is one of the most important—and expensive—decisions you will make in your entire lifetime. Therefore, it is absolutely essential that you approach this milestone with logic, preparation, and financial awareness, rather than just pure emotion.
According to recent real estate observatory studies, the main reasons people want to buy a house are to secure a solid financial investment, stop paying a landlord’s mortgage, and leave a valuable inheritance to their descendants. The desire to own property is deeply cultural; according to Eurostat, 77.3% of Portuguese people live in their own homes.
However, this decision carries a massive financial impact. Economic journals note that over 77.5% of buyers require a bank loan, taking on a debt that often won’t be fully paid off until they reach retirement age.
To ensure your dream home doesn’t turn into a financial nightmare, the Folime real estate team has outlined the five most critical mistakes you must avoid when buying a house.
1. Overestimating Your True Financial Capacity
If you need a mortgage, the loan will obviously need to be approved by the bank. But more importantly, it needs to be approved by you. Many buyers look at the maximum amount the bank will lend them and spend every last cent of it. This is a dangerous trap.
Before you start looking at property listings, you must evaluate your financial stability by asking yourself:
- Can I handle the «Stress Test»? When buying a home, calculate your budget based on a potential rise in interest rates (Euribor). Make sure your monthly payment leaves you with plenty of wiggle room to deal with unexpected life events, like a car breakdown or a medical emergency.
- Do I have real job stability? If you are not part of the permanent staff of your company, or if you recently changed jobs and are still on a probationary period, it is highly advisable to wait a little longer before signing a 30-year contract.
- Can I comfortably pay the down payment? Under current Bank of Portugal rules, banks will only finance a maximum of 90% of the property’s value (or the bank’s appraisal value, whichever is lower). You must have the remaining 10% to 20% in cash. This is known as the down payment, which is usually paid when signing the legally binding Promissory Contract of Purchase and Sale (CPCV).
2. Forgetting the «Hidden» Additional Costs
You found your dream home, you have your 10% down payment saved, and the bank approved the loan. You can breathe a sigh of relief, right? Wrong. The purchase price of the house is just the beginning.
Many first-time buyers completely forget to budget for the heavy transaction costs, which can easily add an extra €10,000 to €20,000 to the upfront bill. You must prepare for:
- Tax Costs: Anyone who buys a house in Portugal must pay hefty taxes to the state on the day of the deed. This includes the Municipal Property Transfer Tax (IMT) and Stamp Duty (Imposto de Selo). You will also be responsible for paying the annual Municipal Property Tax (IMI) going forward.
- Bureaucratic and Bank Fees: You have to pay out of pocket for the bank’s property appraisal, the mortgage dossier fees, the notary who conducts the public deed (Escritura), and the land registry fees.
- Mandatory Insurances: If you use a bank loan, you are legally required to take out a Life Insurance policy (to pay off the house if you pass away) and a Multi-risk Home Insurance policy (to protect the physical structure from fire, floods, and earthquakes).
- Condominium Fees: If you are buying an apartment in a building, you will have to pay a monthly condominium fee for the maintenance of common areas, elevators, and building insurance.
3. Failing to Check the Legal Documentation
Never take a seller or a real estate agent just at their word. Before you sign a CPCV or hand over your deposit, you must verify that the property is legally clean.
Buying a house with hidden legal issues can result in you inheriting someone else’s debts or buying an illegal, unapproved construction. Always ask for and verify these documents:
- Certidão Permanente do Registo Predial: This proves who the actual legal owner is and shows if there are any existing mortgages, penhoras (liens), or debts attached to the house.
- Licença de Utilização: The habitation license issued by the City Hall proving the property is legally approved for residential living.
- Energy Certificate: A mandatory document that shows how energy-efficient the house is, giving you an idea of your future electricity and heating bills.
4. Skipping a Professional Home Inspection
When buyers walk into a beautifully staged home, they often fall in love with the aesthetic—the fresh paint, the modern kitchen cabinets, and the staging furniture. What they fail to look at is the plumbing, the electrical wiring, and the roof.
Skipping a professional home inspection is a massive mistake. A house might look perfect on the surface, but hide toxic mold inside the walls, termite damage in the wooden beams, or an ancient, failing electrical panel. Hiring an independent inspector costs a few hundred euros, but it can save you tens of thousands in unexpected structural repairs during your first year of homeownership.
5. Accepting the First Mortgage Offer You Get
Banks are businesses, and their goal is to make a profit. Taking the very first mortgage offer your primary bank gives you without shopping around is a mistake that will cost you thousands of euros over the life of your loan.
You should request simulations from at least three or four different banks. Pay close attention to the Spread (the bank’s profit margin) and the TAEG/MTIC (the true, total cost of the loan, including all fees and compulsory insurances).
💡 A Financial Tip from the Folime Team:
When negotiating your mortgage, banks will often offer you a lower interest rate only if you agree to buy their specific in-house Life Insurance and Home Insurance. However, bank insurances are notoriously expensive. By law, you have the right to decline the bank’s insurance and hire an independent insurance policy. Even if the bank raises your interest rate slightly, the massive savings you get from a cheaper, third-party insurance premium usually results in a much lower overall monthly bill!
