If you're thinking about buying your first home And if you're missing that initial savings boost, the Guarantee Line from the Ministry of Housing and Urban Agenda (MIVAU), managed by ICO, is just what you've been waiting for: public support for young people and families with dependent children who are solvent and haven't yet been able to save enough.
With this program, The mortgage loan can cover up to 100% of the lower value between appraisal and purchase price (taxes and expenses not included), thanks to a state guarantee of up to 20% of the loan—or up to 25% if the home has an energy rating of D or higher—valid for the first 10 years. The Line is endowed with 2.500 millones de euros and the guarantee is free for both the client and the bank.
What is the ICO mortgage guarantee and what is it for?
The purpose of this Line is open the door of your permanent and habitual residence For those who can afford a mortgage but lack the 20% down payment typically required by banks (financing up to 80% of the value). With public guarantees, the entity can grant you more funding without increasing the interest rate for this reason, since the guarantee has no cost for you or the bank.

Who can apply: groups and general conditions
You can access young people up to 35 years old (none of the buyers may have turned 36 on the day of signing) and families with minors in their care no age limit. In both cases, it must be the first permanent and habitual residence in Spain, also fulfilling the rest of the requirements of the Line.
- Individuals (maximum two purchasers) with legal residence in Spain continuously and uninterruptedly during the two previous years upon request.
- Purchase of a home located within the national territory, intended for permanent and habitual residence.
- Housing cannot be used for economic activity at the time of signing the guaranteed loan.
- not have been owner of another home previously (see exceptions below).
- Not to appear in delinquency in the CIRBE as of the date of signature.
- Not exceeding a net worth of €100.000 per acquiring person.
- That the purchase price do not exceed the maximum set for your Autonomous Community (there is an official table for each Autonomous Community; for example, Madrid €325.000, Aragon €275.000, Castile and León/La Mancha/La Rioja €250.000, Extremadura €200.000).
- Comply with the provisions of the Article 13 of the General Law on Subsidies (Law 38/2003).
Additional requirements if you are young: not exceed 4,5 times the IPREM current (€37.800 gross/year with the reference IPREM). If you buy two young people, the limit of each one is added.
Additional requirements if you are a family with minors: limit of 4,5 IPREM per person (also added if there are two of you) and increases by 0,3 IPREM (€2.520 gross/year) for each dependent minor. In single-parent family the income threshold may be increased by an additional 70%.
Exceptions if you already own a home
In principle, you cannot qualify for a guarantor if you were previously a homeowner; however, there are specific situations in which it is permitted: if you only own an inherited aliquot part (or by transmission mortis causa without a will), If you cannot use your home due to separation/divorce or other causes beyond your control, or if the home is inaccessible due to disability of the owner or of a cohabitant.
Amounts, coverage and financing limits
The guaranteed financing can never exceed 100% of the lowest value between appraisal and purchase price (excluding taxes and fees). In addition, the secured loan must exceed 80% of said reference value (or 75% if the home has energy certification D or higher), because the guarantee covers that additional portion above 80% (or 75%).
The ICO guarantee on behalf of MIVAU can cover up to 20% of the loan and go up to up to 25% when the home has an energy rating of D or higher. Its validity is 10 years from the date of formalization, even if your mortgage has a longer term. The loan, for its part, must have a initial minimum term of 5 years.
If the loan reaches 100% of the reference value, the guarantee will be 20% of the loan (or of the 25% with a grade of D or higher). If you don't reach 100% (but you exceed 80% or 75% in homes with D certification or higher), the Guarantee coverage is adjusted proportionally to the financed amount.
Example: if you ask 95.000 € For a home with a reference value of €100.000, the guarantee would cover the 15,79% of the loan; if the home had an energy rating of D or higher, then the guarantee would reach 21,05%.
Indicative formula for the maximum guarantee percentage: (Mortgage loan amount – 80% x Reference value) x 100 / Mortgage loan amount. For homes with an energy rating of D or higher, the following applies instead of 80%. 75%. Reference value = lower of the purchase price and the appraisal price.
Key deadlines, use of the home and compatibility
The guarantee is valid for the following periods: first 10 years of the mortgage. During that period, the home must be yours habitual residence, unless there are justified circumstances that force you to change it.
The deadline to formalize mortgages under this Line is the December 31th 2025; it is expected that it can be extended to December 31th 2027 depending on demand and through the corresponding MIVAU–ICO agreement.
Regarding compatibility, the Line establishes that The loan cannot have any other guarantee or public endorsement. If you have seen mentions to the contrary, please note that The Line itself specifies the incompatibility with other public guarantees, so it is prudent to adhere to that rule.
Where it is requested and who decides
The request is made in any of the participating credit institutions to the Line of guarantees for first homes for young people and families with minors. The final decision Whether or not to grant financing is up to the bank, which applies its internal risk policies and its usual procedures.
If you have any questions, you can request general information from your bank or on the ICO website, call 900 121 121 (free information service) or contact through form enabled on the ICO page.
Documentation that the bank will ask you for
The entity with which you sign will indicate the specific documentation and will provide you with the declaration forms. In general, they will ask you for:
- Legal residence continuous and uninterrupted residence in Spain for the previous two years: DNI/NIE/passport and cohabitation register (with start date).
- If you qualify for the program for families with minors: family Book, registration of a common-law couple if applicable or birth certificate of the children.

Expenses, typical financial conditions and real-life examples
Just because the State guarantees you doesn't mean the bank will raise your interest rate for it: the guarantee is free and shouldn't involve a higher interest rate. The financing is provided by the institution with its own resources, so you can negotiate. fixed, variable or mixed type and, as always, best market practices will be applied.
You can pay off early (total or partial) as agreed with your bank. If you cancel the entire loan, the guarantee will be automatically extinguishesSome entities establish compensation for early repayment limited to the financial loss with usual caps of 2% for the first 10 years and 1,5% until the end of the loan.
It is common for the bank to offer you or condition bonuses to links (for example, direct deposit of payroll, insurance, etc.). As a representative market example: an entity offers a mortgage to 25 years no opening commission, with bonus option at TIN 2,70% and APR 3,425%, approximate quota of 688,13 € For €150.000 capital (300 installments), total amount owed €221.817,56 including fees, and total cost €71.817,56 in the French system. Without the bonus, the APR would be 3,45% with APR 3,932% and a share close to 746,92 €, total owed €233.790,06 and costs of €83.790,06.
In that same example, the entity assumes certain preparatory expenses (e.g., estimated AJD of €1.125 for €150.000 of liability and rate of 0,75%, registry inspection €10,91, notary €597, agency €363, registry €283) and the client assumes the appraisal (e.g. €289,06). In addition, the customer must have a damage insurance (not necessarily with the bank), and for APR purposes, a typical home insurance policy can be simulated with an approximate annual premium of €317.
Regarding the operating account, there are entities that require maintain an account for the life of the loan: some offer free accounts (such as digital accounts) or apply a maintenance fee, for example, €15 per quarter on standard accounts, a figure that is included in the APR calculation if applicable.
typical examples of type bonus: direct deposit of payroll or average income above €1.200/month (–0,30 points), hire and maintain a life insurance by at least 50% of the capital (–0,30 points) and a home insurance that covers the property (–0,15 points). As a reference, a life insurance simulation for a 30-year-old insured could be close to € 226,58 per year (the actual premium varies by age, capital and coverage). These bonuses usually be reviewed monthly and the rate is adjusted if you stop complying with them.
Common warnings: the breach of obligations may lead to the loss of housing and other assets; the grant depends on the solvency analysis and bank risk criteria; the TAE includes expenses and accessory services under assumptions of premiums and costs; the age of the oldest holder at maturity it is usually limited to 80 years.
Additionally, some entities, if you meet the requirements of the ICO agreement for first home and at least one of the holders being under 35 years old, they allow extend the mortgage term up to 40 years, which reduces the payment at the cost of paying more interest in the long term.
French amortization system and formula
In the French amortization system, you pay a constant rate composed of principal and interest. At first, since there is still a lot of principal to be repaid, interests weigh more; over time, the interest decreases and the principal portion increases.
Illustrative example: for €100.000 over 20 years at 3,75%, the installment would be around 592,89 €The first monthly payment would include approximately €312,50 in interest and €280,39 in principal; the final payment would include just €1,85 in interest and €591,04 in principal, if the interest rate remains unchanged.
Formula (French canon): ak = Ck · ^(-n))], where ak is the installment, Ck is the outstanding capital at the beginning of the period, r is the annual nominal rate (in percentage terms), m is the settlement periods per year and n is the number of outstanding periods.
Housing situation for young people in Spain
Access to housing for young people drags several structural brakes65,9% of young people between 18 and 34 years old were not emancipated in 2022, well above the 2008 figure and also the European average, reflecting difficulties in both renting and purchasing.
La employment status complicates the equation: the youth unemployment rate is around 21,3% compared to 12,1% for the general population, and temporary employment puts pressure on income. Furthermore, youth wages tend to be Lower due to less experience.
Rent weighs more among the emancipated (close to 48,5% of young households live on rent), but the increase in rents In recent years, this has led many to look at purchasing as a more stable medium-term alternative.
Housing has risen in price, especially in large cities, due to shortage of affordable offer and strong demand. Many young people could afford a mortgage, but They don't have the savings for entry, hence the meaning of public guarantees.
Guarantee programs, such as this MIVAU-ICO Line, facilitate access to credit to households with solvency but without sufficient savings for the initial outlay, helping to accelerate emancipation.
Regional aid that can complement your plan
Along with state guarantees, several autonomous communities have launched own programs for purchase or rent, many of them aimed at young people:
- Barcelona: initiatives for new housing, reductions in public housing rents, Revive Madrid for affordable rent, Housing bonus and the program My first home (mortgage of up to 95% for those under 35 years of age).
- the Basque Country: aids GAZTELAGUN for emancipation, support for purchase of used free housing and a housing supplement to cover rental/accommodation costs for people with lower incomes.
- Murcia: guarantee for first home up to 20% from the appraisal, purchase aids in small municipalities and support to payment of rent.
- Andalucía: guarantee for those under 35 years of age 15% of the mortgage.
- Castilla y Leon: youth program Help from YOU for purchase or rent.
- Estremadura: support for purchasing in small towns.
- Balearics: mortgages with 100% financing for a first home under certain conditions.
- La Rioja: specific aids for young home purchase.
There are also regions that prioritize the rental (Navarra, Canary Islands, Aragon, etc.). Get informed well because many of these measures are Compatible between themselves (except for the indicated incompatibility with other public guarantees in the mortgage guaranteed by ICO).
Participating entities and featured programs
Several entities have joined the ICO Guarantee Line for first-time homeowners. Ibercaja, for example, is part of the collaborating entities. Others, such as Caja Rural de Aragón, have launched their “Youth Mortgage”, which allows financing up to 100% of the lowest value between appraisal and sale (without taxes or expenses), with ICO guarantee at no cost, available at branches in Aragon and La Rioja and, through Caixa Rural, also in Catalonia, in addition to an online channel.
Likewise, large banks with decades of experience In financing and solvency (some operating since 1971) are offering competitive conditions and fixed, variable or mixed rate options, adjusted to your risk profile and with possible bonuses by linkage.
Quick questions and helpful clarifications
What expenses should I anticipate when purchasing? Approximately 10% extra on the price for taxes and expenses (appraisal, notary, registration, management, etc.). The guarantee covers the financing, but not taxes and expenses trading.
Can I repay early? Yes, depending on the agreement with your bank. Total cancellation of the loan causes the cancellation of the guarantee. Ask about the compensations for early repayment and its limits.
Who decides if I get a mortgage? financial entity, applying its internal solvency and risk criteria. The guarantee does not imply automatic granting; the bank will assess your income, stability and debt.
Does the guarantee affect the interest rate? It shouldn't. The public guarantee does not make the rate more expensive by itself because it is free for both the client and the entity. The final interest depends on market, profile and connection.
Can I use my home as a business? No. At the time of signing the secured mortgage you cannot allocate the home to economic activity.
What price cap is there per regional government? maximum limits by community (see official table). As a guide: Madrid €325.000, Aragon €275.000, Castile and León/La Mancha/La Rioja €250.000, Extremadura €200.000.
