What is the ICO Guarantee for Young Homebuyers' Mortgages and How It Works in 2026

# What is the ICO Guarantee for Young Homebuyers' Mortgages and How It Works in 2026

The ICO Guarantee for Young Homebuyers' Mortgages is a public guarantee that the Instituto de Crédito Oficial (ICO) provides to the bank granting your mortgage, covering part of the risk of non-payment. In practice, it allows you to finance up to the 100% of the appraised value of your first home when you don't have sufficient prior savings to cover the 20% that banks usually require as a down payment.

The program was approved through a Royal Decree and is regulated by the Ministry of Housing and Urban Agenda (vivienda.gob.es). The ICO acts as a guarantor to the bank, not as a direct lender: the mortgage is signed with your usual financial institution, and the ICO guarantees part of the loan in case you cannot pay it.

How much does the ICO Guarantee cover in 2026? According to the current regulations of the program (ICO, ico.es), the guarantee can cover up to 20% of the loan amount for general buyers, and up to 25% for young people under 35 years old and families with dependents. This means that if the bank finances 80% of the appraised value, the ICO Guarantee covers the additional portion up to 100%, reducing the risk for the institution and facilitating mortgage approval.

Status of the Program After the Suspension in April 2026

This is the point that no other resource explains clearly: in April 2026, the program was temporarily suspended, according to information published by media such as El Mundo (30/04/2026). This suspension affected the opening of new applications during a limited period while the Ministry of Housing reviewed the budget allocation and eligibility criteria.

As of the date of writing this article (June 2026), the situation is as follows:

• Applications already initiated before the suspension continue their normal processing and have not been canceled.
• New applications are subject to the availability of the current budget allocation at any given time. Before starting the process, it is essential to confirm with your affiliated bank if the program is active for new requests.
• The extension of the program until 2027 is planned within the framework of the State Housing Plan, although the specific conditions must be consulted in vivienda.gob.es and ico.es, as they may change.

Practical Recommendation: Contact directly with your chosen affiliated bank and the ICO (ico.es) to verify the current status of the program before starting any management.

Requirements to Apply for the ICO Guarantee in 2026: Age, Income, and Type of Housing

To access the ICO Guarantee for First Home 2026, you must simultaneously meet all the requirements established in the regulatory legislation of the program (BOE, Royal Decree regulating the ICO Guarantee Program — boe.es):

Personal Requirements

• Age: You must be under 35 years old at the time of the application. If you are exactly 35 years old in 2026, you must verify whether you have already reached that age before the signing date: the limit is strict. Families with dependents can access the program regardless of age.
• Tax residency in Spain: You must be a tax resident in Spanish territory.
• First home: You cannot be the owner of any other home in Spain or abroad at the time of the application. If you have an inherited or donated home, consult the exceptions provided in the legislation.
• Usual and permanent use: The acquired home must be destined for habitual and permanent residence, not for a second home or rental.

Economic Requirements

• Income limit: According to the current legislation in 2026 (Ministry of Housing, vivienda.gob.es), the annual gross income threshold is around 37,800 euros for individual applicants (4.5 times the IPREM). For family units with children, this limit increases. Consult the exact current amount in ico.es, as it may vary according to the current call.
• Payment capacity: The bank will evaluate your solvency independently of the guarantee. The ICO Guarantee does not guarantee mortgage approval; it only reduces the risk for the institution.

Requirements on the Housing

• Maximum price: The home cannot exceed a purchase price determined by the legislation. According to the conditions published by the ICO, the approximate limit is 250,000 euros, although this amount may vary according to the autonomous community and the call. Verify the exact amount in ico.es before searching for housing.
• New construction and second-hand: The ICO Guarantee covers both new construction and second-hand homes, as long as they meet the price and use requirements.
• Location: There are no general geographical restrictions, but some autonomous communities may have additional conditions in the management of the program.

Practical Example of Eligibility

Suppose you are 32 years old, have annual gross income of 28,000 €, and want to buy an apartment for 190,000 € in Valencia. In principle, you would meet the requirements of age, income, and housing price. The bank could finance up to 190,000 € (100% of the appraised value), with the ICO guaranteeing the portion between 80% (152,000 €) and 100% (190,000 €), that is, 38,000 €. Your monthly payment would depend on the negotiated interest rate and the term, but with a fixed rate of 3.5% over 30 years, the approximate monthly payment would be around 853 €/month (estimate; use a mortgage calculator for your specific case).

Which Banks Offer Mortgages with ICO Guarantee in 2026 and How to Compare Them

The ICO Guarantee is not requested directly from the ICO, but through the financial institutions affiliated with the program. It is the banks who submit the application to the ICO on behalf of the client.

According to the information published by the ICO (ico.es), the main institutions affiliated with the program in 2026 include the major banks with national presence. However, not all banks participate in all autonomous communities or at all times of the year, as participation depends on specific agreements with the ICO.

How to Compare Mortgages with ICO Guarantee

Before choosing a bank, compare these key elements:

• TAE (Annual Equivalent Rate): It is the real cost of the loan, including commissions and linked products. Do not rely solely on the TIN.
• Interest rate: Fixed, variable, or mixed. In 2026, with the euribor at moderate levels, fixed rates offer greater predictability.
• Linked products: Some banks require contracting life insurance, home insurance, or domiciling your salary as a condition to access the ICO Guarantee. Calculate the total cost.
• Commissions: Opening, early repayment, and transfer.
• Maximum term: Generally up to 30 years for mortgages with ICO Guarantee.

Tip: Use the mortgage comparator from the Bank of Spain (bde.es) to compare offers from different institutions before committing to any.

How to Apply for the ICO Guarantee Step by Step: From the Bank to the ICO and Notary Signing

This is the real process you must follow to obtain the ICO Guarantee for Young Homebuyers' Mortgage 2026, with approximate timeframes for each phase:

Step 1: Verify Your Eligibility (1-2 days)

Before going to the bank, check that you meet all the requirements: age, income, absence of other properties, and housing price. Gather the basic documentation: DNI, latest income tax returns (AEAT), work history (Social Security), and employment contract or documentation of self-employment if you are self-employed.

Step 2: Request the Mortgage with ICO Guarantee at the Bank (1-3 weeks)

Go to an institution affiliated with the program and request a mortgage with ICO Guarantee explicitly. The bank will analyze your solvency and, if the operation is viable, initiate the guarantee application to the ICO. In this phase, the bank will provide you with the FEIN (European Standardized Information Sheet) with the loan conditions.

Step 3: Guarantee Processing by the ICO (2-6 weeks)

The ICO evaluates the application submitted by the bank. This is the phase where delays may occur, especially during periods of high demand or after a suspension like the one in April 2026. If your file was in progress before the suspension, the ICO will resume it without needing to restart it.

Step 4: Appraisal and Binding Offer (1-2 weeks)

Once the guarantee is approved, the bank orders the official appraisal of the home. With the appraisal in hand, the bank provides you with the binding offer with the definitive loan conditions.

Step 5: Notary Signing

You have a minimum of 10 natural days from receiving the binding offer to review it before signing (Law 5/2019 regulating mortgage contracts). The signing takes place before a notary, who will verify that you understand the loan conditions.

Common Documentation Required by Banks

• DNI or NIE valid
• Latest 2-3 income tax returns (AEAT)
• Latest 3 pay slips or income documentation
• Work history report (Social Security)
• Simple note from the Property Registry (to prove you don't have other properties)
• Contract of deposit or deposit of the home to buy
• Certificate of enrollment

Compatibility of the ICO Guarantee with Other Aids and Deductions

The ICO Guarantee is compatible with the autonomous regional aids for access to housing in most autonomous communities, although you must verify this in each case, as some regions have their own programs that may have specific compatibility conditions.

Regarding tax deductions in the IRPF, the state deduction for investment in habitual housing is only valid for acquisitions prior to 2013 (transitory regime, AEAT). However, several autonomous communities maintain their own deductions for the purchase of a first home for young people in 2026. Consult the conditions of your community on the AEAT website or the corresponding autonomous tax portal.

The ICO Guarantee is also compatible with the State Housing Plan 2022-2025 extended in its aid programs for access, provided that there is no double financing of the same concept.

Frequently Asked Questions and Errors to Avoid Before Applying for the ICO Guarantee

Most Common Errors When Applying for the ICO Guarantee

• Going to a bank not affiliated: Not all banks participate in the program. Check beforehand in ico.es.
• Not checking the maximum housing price: If the price exceeds the established limit, the operation is not eligible even if you meet the other requirements.
• Confusing the ICO Guarantee with a subsidy: The guarantee does not reduce the amount you have to repay. You still pay the 100% of the loan plus interest.
• Not considering additional costs: Although the guarantee covers 100% of the purchase price, notary, registration, appraisal, and tax costs (IVA or ITP depending on the housing type) are not covered and may account for between 8% and 12% of the price.
• Starting the search for housing without pre-approval: Search for pre-approval first to know with what real budget you have.
