How to rent out your flat while protecting yourself from non-payment
Fear of non-payment stops more rentals than actual defaults. With an orderly screening process, the right legal guarantees and good insurance, the risk drops to a tiny fraction. This guide explains how.
Every year, thousands of owners in Barcelona decide not to rent out their second home for fear of non-payment. And yet the real default rate in Spain is around 4 % of contracts —and the vast majority are resolved without going to court.
The problem isn't the risk: it's risk management. Esta guía recorre los nueve pasos esenciales para que un piso en alquiler pase de ser una preocupación a ser una renta predecible. Ley actualizada, garantías reales y la opción —cuando conviene— de delegar.
Fear and the real data
Fear of non-payment is real, but the statistics paint a much more manageable picture than it seems. In Spain, the effective default rate stays between 3% and 5% of active contracts depending on the year. In most of those cases, the default is resolved within three months.
That means nine out of ten rentals are paid on time and without incident. La diferencia entre estar en ese 90 % y estar en el grupo problemático no es la suerte: es el rigor en los pasos previos a la firma.
Screen the tenant before anything else
The most important step in the process happens before showing the home. A well-structured ten-minute phone call eliminates between 60% and 80% of unsuitable candidates without needing a viewing.
- Type of employment contract and length of service
- Net monthly income (usual rule: rent ≤ 35% of income)
- Number of people who will live in the property
- Pets, family situation, desired term
- Reason for moving
Solvency scoring and verification
Once serious candidates have been identified, verification follows. The minimum documents to request include: ID, employment contract, last three payslips, employment history and the latest income tax return. For the self-employed, the quarterly form 130 and the annual summary.
There are professional scoring services that cross-check this data against debtor databases (ASNEF, Fichero de Inquilinos Morosos) and issue a report within 24-48 hours. The cost is around €30-50 per candidate.
Deposit and additional guarantees
The Urban Leases Act (LAU) sets clear limits:
- Mandatory deposit: one month's rent for a main residence. In Catalonia it must be lodged with INCASÒL.
- Additional guarantee: maximum two months' rent. It can be a deposit or a bank guarantee.
- Legal maximum total: three months' rent. Any higher requirement is void.
- Personal guarantee from a third party: not considered an additional guarantee and therefore does not count towards the limit.
The deposit cannot be used to pay the last months' rent. It must be returned within one month of handing back the keys.
Rent default insurance
Rent default insurance is, today, the most effective tool for neutralising financial risk. In exchange for an annual premium of 3% to 5% of the annual rent, the insurer guarantees:
- Payment of unpaid rent for up to 12, 18 or 24 months
- Legal defence of the owner in the eviction
- Cover for vandalism and damage to the property
- A solvency study of the candidate as a precondition
The key point: most insurers require the tenant to have passed their solvency check before signing the contract.
The robust contract
Clauses worth reviewing in every rental contract in 2026:
- Exact duration, legal extensions and notice of non-renewal four months in advance
- Rent update clause linked to the applicable legal index
- Allocation of costs (utilities, IBI, owners' association)
- Detailed furniture inventory with attached photos
- Express prohibition on subletting without written consent
- Direct debit and consequences of a returned payment
- Termination clause for non-payment with a defined period
Warning signs: when not to sign
Signs that almost always point to problems:
- Reluctance to provide full documents or undergo the solvency check
- Unjustified urgency to move in «this very week»
- Offer to pay several months in advance in cash without a signed contract
- Refusal to pay the rent by direct debit
- Mismatch between declared income and apparent standard of living
- A history of changing address every few months
Proactive rent collection
The difference between one month and six months of non-payment usually lies in the response on day one.
A simple protocol: direct debit, automatic alert if the payment is returned, a phone call the same day, a written demand after seven days, and formal notice by burofax if after fifteen days there is neither payment nor agreement.
If non-payment happens: fast-track eviction
When the default becomes established, the legal tool is the so-called fast-track eviction for non-payment:
- At least one month after the default, a payment order claim (demanda monitoria) is filed
- The court gives the tenant ten days to pay, object or vacate
- If there is neither objection nor payment, an eviction date is set
- The eviction is usually carried out between three and nine months after the claim
With rent default insurance in place, the whole process is handled by the insurer —with its lawyers and court representatives— while the owner keeps receiving the monthly rent.
