Renting in Madrid as an expat: fianza, extra guarantees and the LAU lease

The framework: the LAU and the residential lease

In Spain, renting a home is governed by the Ley de Arrendamientos Urbanos (Law 29/1994, known as the “LAU”), amended in particular in 2019 and again by the 2023 housing law (Law 12/2023). It draws a line between two kinds of lease, and the difference matters to you directly:

• the residential lease (arrendamiento de vivienda), where the property is your habitual, permanent home;
• the lease for a use other than housing (uso distinto de vivienda), which covers business premises but also the seasonal lease (arrendamiento de temporada), signed for a temporary need of the tenant.

If you are moving to Madrid to live there, a residential lease is what fits your situation. Its rules protect the tenant:

Point	General rule for a residential lease
Term	The tenant can stay at least 5 years if the landlord is an individual, 7 years if it is a company. The contract can be signed for one year: it then renews year by year, at the tenant's option, up to that minimum.
Extension	After that period, unless either party gives notice, the lease is tacitly extended year by year for up to 3 more years.
Leaving early	The tenant can leave after 6 months, giving at least 30 days' notice. The contract may provide for compensation, within limits set by law.
Energy certificate	The landlord must provide it.

The rules above are the general principles of the law. The LAU has been amended several times in recent years; if you are unsure about a specific point, refer to the consolidated version currently in force.

Fianza, guarantees, advance rent: what can be asked

This is where expats most often get caught out, because they arrive assuming that “no track record means paying more”. Yet the law sets precise caps.

The fianza: mandatory and regulated

The fianza is the statutory security deposit. It is mandatory and amounts to:

• one month's rent for a residential lease;
• two months' rent for a lease for a use other than housing, which includes the seasonal lease.

In the Comunidad de Madrid, the landlord must deposit the fianza with the regional administration. It does not stay in their bank account. You can ask for proof of deposit: a landlord who is in order will have no trouble sending it.

Additional guarantees: capped at two months

On top of the fianza, the landlord can require an additional guarantee: an extra deposit or a bank guarantee (aval bancario), meaning your bank commits to pay on your behalf if you default. For a residential lease of up to 5 years (7 if the landlord is a company), this additional guarantee is capped at two months' rent.

Rent in advance: one month at most

The landlord cannot demand more than one month's rent in advance. Requests for “six months upfront” or “a year paid in advance”, very common with foreigners, are not lawful for a residential lease.

Amount	Residential lease
Fianza	1 month, deposited by the landlord with the Comunidad de Madrid
Additional guarantee (deposit or bank guarantee)	2 months maximum (leases up to 5 or 7 years)
Rent in advance	1 month maximum
Agency and contract drafting fees	Paid by the landlord

Agency fees: paid by the landlord

Since the 2023 housing law, real-estate management and contract formalisation costs are borne by the landlord. On a residential lease, the tenant should not pay agency fees. If an agency marketing a flat on the owner's behalf hands you a “file fee” or “search fee”, ask about it directly. A different situation: if you hire a professional to search on your behalf, you pay for that service.

Rent reviews

Rent can only be updated each year if the contract provides for it. Since 2025, the update refers to a specific index published by the INE, the “IRAV”. The rules have changed several times: read the clause in your contract and check the applicable rule on ine.es when the review comes round.

No Spanish payslips: your options

The real obstacle is practical, not legal. A Madrid landlord typically asks for your last three nóminas (payslips), a Spanish employment contract and sometimes your tax return. You arrive with foreign documents, no local banking history, sometimes no NIE yet. Several levers exist, and they can be combined:

• An employer letter confirming your role, salary and start date, ideally on letterhead and together with the contract. If your company is relocating you, this is the most convincing document.
• A company lease. Some employers rent directly for their assignees: the landlord then deals with a solvent company. In that case, check that you will still be able to register on the padrón at that address.
• A bank guarantee, within the legal cap of two months of additional guarantee. It ties up money in your Spanish account but reassures landlords a great deal.
• A guarantor resident in Spain (fiador), who personally commits to pay if you default. Useful if you have family or friends already settled here.
• Rent-default insurance (seguro de impago de alquiler), taken out by the landlord. The insurer assesses your file; if it accepts it, the landlord is covered and their reluctance often disappears.

Traps and scams

Expats searching from abroad are the favourite target of fraudulent listings. The typical script: a very well-located flat, rent slightly below market, a “landlord” who lives abroad and cannot show it, but offers to post you the keys once a deposit is received.

Other reflexes:

• No untraceable payments: no cash without a receipt, no money-transfer services, no cryptocurrency. A bank transfer to an account in the landlord's name, with a clear reference.
• Be wary of “reservation fees” requested before any viewing or contract. If you do pay to hold a flat, insist on a written document stating what it is for and when it is refunded.
• Refuse requests for several months upfront: beyond one month it is unlawful on a residential lease, and it is a warning sign in itself.
• No verbal leases. You need a written contract, if only for the padrón and to get your fianza back.

The checklist before you sign

A Spanish lease should be read in full, in Spanish, before you sign. Points to check every time:

1. Landlord's identity: does the name on the contract match the nota simple? If not, who is signing, and in what capacity?
2. Inventory and photos: attach to the contract an inventory of the furniture and the condition of the property, with dated photos. It is your best protection for getting the fianza back.
3. Meter readings for electricity, gas and water on move-in day.
4. IBI and community fees: these are only yours to pay if the contract expressly says so, with a stated amount.
5. Utility contracts: whose name are they in, or will they be in? See our guide to electricity, gas and water in Madrid.
6. Empadronamiento: the lease must not prevent you from registering on the padrón. A clause that blocks it will hold you up for your health card, school places and driving licence. Details in our empadronamiento in Madrid guide.
7. Break clause: what compensation applies if you leave before the end of the term? If you know your assignment could be cut short, negotiate it now.
8. Pets: if you have any, get them accepted in writing in the contract.
9. Repairs: as a rule, small repairs caused by ordinary wear and tear are the tenant's responsibility; works needed to keep the home habitable fall to the landlord. Check that the contract does not reverse this balance.
10. Energy certificate: ask for it.

During the lease and when you leave

During the lease, report any fault in writing (an email or a message you keep), dated and with photos. A written record settles most later disagreements about the cause of damage.

When you leave:

• Notice: respect the period in the contract, at least 30 days if you are leaving early after the first six months, and send it by a method that leaves proof (burofax, or email with acknowledgement, depending on what the lease provides).
• Check-out inventory: carry it out together with the landlord, going through the move-in inventory point by point, with photos. Take meter readings.
• Fianza: the landlord must return it within one month of the keys being handed back, minus any justified deductions (damage beyond normal wear, unpaid bills). After that, the amount owed accrues interest at the legal rate.
• Utilities and padrón: cancel or transfer the contracts in your name, and update your address if you are staying in Spain.

In a serious dispute (an unjustified deduction from the fianza, a refusal to carry out necessary works), start with a formal written demand. If the disagreement continues, it is a matter for a lawyer.

Frequently asked questions

Can the landlord demand six months' rent upfront because I have no Spanish payslips?

Not on a residential lease. They can ask for at most one month's rent in advance, the one-month fianza and an additional guarantee capped at two months (deposit or bank guarantee) for leases of up to 5 years, or 7 if the landlord is a company. Offer an employer letter, a bank guarantee or a guarantor instead.

Do I have to pay agency fees?

On a residential lease, since the 2023 housing law, real-estate management and contract drafting costs are borne by the landlord. You only pay for a service you commission yourself, such as a search carried out on your behalf.

How do I know the fianza has been deposited?

Ask the landlord for proof of deposit with the Comunidad de Madrid. It is a legal obligation for them, and the document is easy to send.

I'm only staying ten months. Is a seasonal lease the right fit?

A seasonal lease is meant for a genuine temporary need (a short assignment, studies and so on), with a two-month fianza and a different regime from the residential lease. The rules have changed recently: check the version in force and have the contract reviewed. If Madrid becomes your habitual home, a residential lease applies, and you can leave after six months with 30 days' notice in any case.

What if my fianza isn't returned?

The landlord has one month from the handover of the keys. After that, the amount accrues interest at the legal rate. Send a written claim backed by the move-in and check-out inventories and photos; if nothing happens, it becomes a matter for a lawyer.

Who pays for a broken boiler?

Repairs needed to keep the home habitable, including a boiler that has failed through age, are in principle the landlord's responsibility. Small repairs caused by everyday use fall to the tenant. Report the fault in writing as soon as it happens.
