Government-Backed Mortgage: Support for Young Buyers under 35

07.11.2025
Discover how public guarantees and tax exemptions in Portugal are making it easier for young buyers under 35 to get a home loan. 

In 2024, the Portuguese government introduced new measures to make it easier for young people under 35 to buy their first home. With government-backed mortgage guarantees and significant tax exemptions, the cost of getting started has dropped — and the door to home ownership is now more open than ever.

If you're thinking about buying your first home with a mortgage, this could be the right time to move forward.

What changes with the State Guarantee for young homebuyers?
The key change is the possibility of getting up to 100% financing on your first primary residence, thanks to a State personal guarantee. This guarantee works like a public guarantor, covering up to 15% of the loan amount if the borrower is unable to meet the repayment obligations.

This measure is already in force under Decree-Law no. 44/2024.

Who is eligible for the guarantee?

To benefit from the State-backed guarantee, applicants must meet the following criteria:

  • Be aged between 18 and 35 (inclusive);
  • Have fiscal residence in Portugal;
  • Have their tax and social security status regularised;
  • Earn up to the 8th IRS income bracket (currently up to €80,000/year);
  • Own no residential property;
  • Not have previously benefited from this guarantee.
Additionally, the property must:
  • Be intended for permanent residence;
  • Have a transaction value of €450,000 or less.
Additional tax exemptions for buyers under 35

The new legislation also includes financial relief for eligible buyers:
  • IMT (Property Transfer Tax): full exemption up to €316,772;
  • Stamp Duty: exemption on both purchase and mortgage contract;
  • Notarial and registration fees: exemption or reduction.
These incentives are defined in Decree-Laws no. 48-A/2024 and 48-D/2024.

Practical example: how much can you save?

Let’s say you’re buying a home for €200,000:

Without tax benefits:
  • IMT: €4,910.81
  • Stamp Duty: €2,680
  • Total cost: €7,590.81
With tax benefits:
  • IMT: €0
  • Stamp Duty: €0
  • Total cost: €0
Real savings for buyers under 35: €7,590.81
