Buying a home is one of the most important financial decisions of a lifetime — and also one that generates the most avoidable mistakes, especially among those buying for the first time in Portugal. Here are the seven most common.

1. Not having mortgage pre-approval

Viewing properties without knowing how much credit you can obtain leads to wasted time — and sometimes the right property — to those who already have financing secured.

2. Ignoring legal due diligence

Checking the permanent certificate, the land registry and any charges or mortgages on the property is essential before signing any CPCV.

3. Underestimating transaction costs

IMT, Stamp Duty, notary and registration can add up to 6-8% of the purchase value — a figure many buyers only discover too late.

"The most expensive mistake is not overpaying for the property — it is forgetting the 7% in taxes and fees that add to the list price."

4. Not visiting at different times of the day/year

Light, noise, traffic and even damp vary with the hour and the season. Visit more than once before deciding.

5. Neglecting the state of the energy certification

A property with a low energy rating may require significant insulation work — a factor to consider in the final price.

6. Relying on photographs alone

Wide angles and good artificial lighting hide flaws. Always request an in-person viewing or a detailed virtual tour.

7. Not involving an independent lawyer

Even with a good estate agent, an independent lawyer protects your interests exclusively in the review of the contract.

FOZ VILLA supports its clients through each of these steps, with trusted partners for legal due diligence and financing.
