Mortgages for young buyers under 35 in Spain

The Spanish mortgage system asks young buyers for a 20% deposit plus taxes — roughly 30% of the property price — knowing most of them don't have it. Then politicians announce guarantees and discounts to solve the problem the system created. Still, the aid exists and you should use it. The interest rate is rarely the problem. The deposit is.

The ICO guarantee for first-time buyers

The ICO guarantee (aval ICO) is the Spanish government's flagship measure for young buyers and families with children. The Official Credit Institute (Instituto de Credito Oficial) guarantees part of the loan so the bank can finance up to 100% of the property value without requiring the standard 20% down payment.

The real experience from users: the theory sounds great, but not every bank processes it smoothly. A user in Madrid — a young couple aged 32 and 31 earning EUR 3,800 combined — reported that after weeks searching for a 100% mortgage with ICO guarantee, only a handful of banks actually handled it efficiently, usually through a broker. Rates for ICO-guaranteed mortgages tend to run slightly higher than standard offers, but the advantage of not needing the full deposit makes up for it if you lack the savings.

Bank discounts for young borrowers

Several banks apply an extra rate discount (bonificacion) while one of the borrowers is under 35:

• Kutxabank/Cajasur: automatic additional 0.10% discount while the oldest borrower is under 35. One user secured a 5-year mixed rate at 1.60%, with potential to drop to 1.40% with full tie-ins (vinculaciones), including the youth discount.
• Ibercaja: also offers specific conditions for under-35s, especially on mixed-rate products (hipoteca mixta).
• Unicaja: one user reported a mixed rate starting at 1.35% for 6 months, then 1.25% until month 60, then variable.

The youth discount is temporary — it disappears when you turn 35. It does not transform the mortgage, but it saves money during those years.

Regional tax reductions

This is money many young buyers leave on the table by not looking into it. The property transfer tax (ITP — Impuesto de Transmisiones Patrimoniales) for second-hand property varies significantly by age and region (comunidad autonoma):

• Andalusia (Andalucia): ITP reduced to 3.5% for under-35s buying their first primary residence (versus the general rate)
• Valencia (Comunidad Valenciana): 8% reduced rate for first primary residence of under-35s when the property value exceeds EUR 180,000, with income limits
• Madrid: 10% ITP discount for primary residence, not youth-specific but combinable
• Other regions have their own reductions — check before buying

One user put it well: "I don't understand the tax burden when buying a first home as a young person. At least 5.4% ITP in Madrid, which is easily EUR 10,000 at current prices, plus notary, registry, legal fees..." Every reduction you can claim matters.

Regional guarantee programmes

In addition to the national ICO guarantee, some regions run their own programmes:

• Andalusia: a youth housing guarantee programme (garantia vivienda joven) that allows financing up to 95% through participating banks for under-35s. One user reported being offered 95% financing with reasonable rates, tying in payroll, home insurance, and life insurance.

Real rates young buyers are getting

• Young couple (both <35), EUR 3,800 net, Madrid: seeking 100% mortgage with ICO guarantee, offers around 2.5-2.8% fixed
• Young couple, Kutxabank, 7-year mixed: 1.60% for the first 7 years, then Euribor+0.20% with discounts, plus 0.10% additional youth discount
• Cajasur/Kutxabank, 5-year mixed: from 1.69% with payroll, card, insurance, and youth discount

What worries young buyers most

The pattern that repeats in the forums is not the interest rate but the down payment (entrada). Young people with stable employment but insufficient savings for the 20% deposit plus taxes — which easily add up to 30% of the purchase price — are the majority. The ICO guarantee and regional programmes exist precisely for this, but the process is not always smooth.

The most consistently repeated advice

Research your region's (comunidad autonoma) buyer assistance schemes before signing anything. The difference between paying 8% ITP and 3.5% on a EUR 200,000 property is EUR 9,000. And if you do not have the full deposit, ask specifically about the ICO guarantee (aval ICO) — not every bank advertises it, but many will process it if you ask.
