A family lost more than €27,000 because they trusted “a friend who knew the Portuguese property market.”
They had finally decided to relocate to Portugal and found what seemed to be the perfect apartment for €420,000.
Trying to save money, they skipped professional assistance and relied on informal advice.
Unfortunately, what appeared to be a straightforward purchase became an expensive lesson.
The Problems Only Appeared After Signing
The property had legal issues that were never identified before the reservation agreement was signed.
No one verified whether the documentation was complete, whether there were outstanding charges registered against the property, or whether the agreed price reflected the actual market value.
Then came an even more expensive mistake.
Because the purchase was made before their relocation strategy and Portuguese tax position had been properly planned, the property was acquired under conditions that resulted in significantly higher taxes than necessary.
By the end of the transaction, they had spent over €27,000 beyond their original budget between unnecessary taxes, legal costs, delays and additional financing requirements.
All of it could have been avoided.

Tax Planning Before You Buy Can Save Thousands
One of the biggest mistakes international buyers make is purchasing property before properly planning their Portuguese tax residency.
Many buyers intend to live permanently in Portugal but complete the acquisition before becoming Portuguese tax residents or without understanding how the property should be classified.
This can affect whether the purchase is treated as a primary permanent residence or as a second home, resulting in higher acquisition costs and unnecessary taxation.
Proper planning before signing can make a substantial financial difference.
Prismaat works alongside buyers to ensure the purchase is structured correctly from the outset, helping clients understand:
- ✔ IMT (Municipal Property Transfer Tax)
- ✔ Stamp Duty
- ✔ Primary Residence vs Second Home tax implications
- ✔ Portuguese Tax Residency timing
- ✔ Administrative requirements before completion
