Best FSBO websites in Spain

Yes. Idealista allows private owners to list directly under the 'particular' category. The first two active listings are free. If you have more than two listings at once, or if your property is priced above 1,000,000 euros, Idealista charges a fee. You do not need an agency or a NIE to post, but you will need one to sign the final deed.

The main cost for sellers is the plusvalia municipal (official name: Impuesto sobre el Incremento de Valor de los Terrenos de Naturaleza Urbana), a local tax on the increase in land value since you acquired the property. The amount is calculated by the ayuntamiento (local council) and varies by municipality and how long you have owned the property. Sellers also pay capital gains tax (IRPF for residents, IRNR for non-residents) on the profit from the sale. Non-residents have a mandatory 3 percent withholding applied at notary: the buyer retains it and pays it to the tax authority on your behalf. Notary fees for the deed are typically split or paid by the buyer, but confirm this in your sale contract.

The arras penitenciales is a private deposit contract, usually for 10 percent of the purchase price, signed between seller and buyer before the notary deed. It locks in the price and a closing date. If the buyer pulls out, they forfeit the deposit. If the seller pulls out, they must return double the deposit. It is legally binding and commonly used across Spain. You can draft one without an agent, but a gestor or abogado (property lawyer) can review it for a few hundred euros and is worth it.

Neither is legally required, but most sellers hire one or both. A gestor handles administrative filings, tax declarations, and NIE paperwork. An abogado reviews the arras contract, checks for encumbrances on the registro de la propiedad (land registry), and confirms no community fees or IBI (annual property tax) are outstanding. Total fees for both, on a standard sale, typically run 1,000 to 2,000 euros. Non-residents and sellers of inherited property especially benefit from having an abogado.

You need: the escritura (title deed), a nota simple from the registro de la propiedad (confirms ownership and any mortgages or charges), the certificado de eficiencia energetica (energy performance certificate, legally required before listing, issued by a certified technician for roughly 100 to 300 euros depending on property size), proof that IBI is paid, and a certificado de la comunidad de propietarios if the property is in a building with owners' community fees. If there is an outstanding mortgage, you will need a certificado de deuda pendiente from the bank.

Any buyer who does not have a Spanish NIE (Numero de Identificacion de Extranjero) must obtain one before signing at the notary. That is the buyer's responsibility, but be aware it can add a few weeks to the timeline. Payment usually arrives via bank transfer to a Spanish account on signing day. If your buyer is financing, their Spanish bank will require a tasacion (official appraisal) of the property. Platforms that already reach buyers across multiple countries can reduce the time you spend sourcing international interest yourself, and buyer identity verification confirms who you are dealing with before you invest time in an offer.

Across the five platforms here, only two ever bill a private seller. Idealista is free for the first two listings, then charges for additional listings and for properties whose asking price tops 1,000,000 euros. Wallapop is free at the base level and sells paid boosting as an optional extra. The other three carry no seller fees: Fotocasa at its basic private tier, Milanuncios with no cap on ads, and Anyone.com, whose published pricing includes neither a listing fee nor a commission to the platform, at any listing count or price band. A zero in the fee column describes what the platform takes from you, not how many Spanish buyers will see the listing. Idealista's charges buy placement in front of the audience that dominates Spanish property search, while Anyone.com publishes no Spanish traffic or transaction figures, leaving its local reach unproven where Idealista's dominance is documented. Whichever channel or combination a seller uses, the costs that remain at completion are Spain's usual notary and closing obligations, which no platform fee schedule changes.

Spanish agency commission generally lands between 3 and 5 percent, calculated on the sale price and due at completion. No national tariff fixes the rate, so it is whatever seller and agency agree, and on a typical sale that single line item outweighs every charge in the platform table above, where the only fees are Idealista's beyond two listings or above 1,000,000 euros and Wallapop's optional boosts. Finding the agent does not have to add to that cost. This site keeps its own Spain-specific directory of ways to reach a local professional at /countries/spain/find-an-agent. Anyone.com fields an agent-matching tool too, found at anyone.com/find-agent, and the claims attached to it are the company's: candidate agents are selected against the listing's location, price bracket, size, and property type; no fee attaches to the introduction on the seller's side or the buyer's; and the pool those candidates come from numbers 4.6 million agents, a count supplied by Anyone.com itself. Either route ends with an agent who charges commission, so the 3 to 5 percent rate is the number to negotiate regardless of how the introduction happens.

The most common problems are: missing or expired energy certificate (required before marketing, not just at signing); outstanding debts on the property such as unpaid IBI, community fees, or a mortgage that was not formally cancelled at the registro; underestimating the plusvalia municipal, which can be significant in areas where land values have risen sharply; and non-residents not accounting for the 3 percent withholding at closing. Getting a nota simple and a certificado de comunidad before you list prevents most of these surprises.
