Buy-to-Let Mortgage in Cádiz: What UK Investors Should Know

Investors from the United Kingdom who want to buy a flat or house in Cádiz to let it out usually assume the mortgage process will look different from a residential purchase. In practice, Spanish banks still start from the same foundations: a Spanish tax number (NIE), a Spanish bank account, proof of income from the United Kingdom, and a study of the buyer's overall financial profile. What changes is how each lender weighs the rental income the property may generate, and that varies from bank to bank.

At Colibrí Finances we compare more than 20 Spanish banks to find those most open to buy-to-let applications from abroad, prepare the file, translate the documents the bank asks for and follow the process through to the notary. The study is free and without obligation, and we only charge a fee if you go on to sign, always agreed with you in writing beforehand.

Cádiz province stretches along the Atlantic Costa de la Luz, known for whitewashed towns, wide sandy beaches and a windier climate than the Mediterranean coast, with Tarifa a hub for windsurfing and kitesurfing. Buyers here often want an authentic Andalusian setting rather than a purely resort atmosphere.

Jerez airport serves the area, with Gibraltar and Seville also within driving distance. The coast is lively in summer but quieter otherwise, and property ranges from town houses in historic centres to villas near the beach or countryside fincas further inland.

What follows are measured, dated figures for Cádiz (province) — who lives there, what homes are advertised for, how to get there and the climate — each one sourced. They help you build a realistic picture of Cádiz (province) as you work out the budget for a Spanish mortgage.

According to the INE annual census, 1,261,420 people were registered as living in the whole of Cádiz province on 1 January 2025. The count takes in every town and village across the province, not only its capital. The province of Cádiz counts 68,798 residents with a foreign passport, close to 5 out of every 100 people. That is a modest figure province-wide, though some towns within it stand well above the average.

INE's register shows 7,150 British nationals living in the province of Cádiz as of 1 January 2025, making it one of the province's largest foreign communities. That points to a community that is firmly rooted across the province. In 2021 there were 6,587 registered, fewer than today. The growth since then indicates the community has kept attracting new arrivals. The following table shows the leading foreign nationalities registered in Cádiz (province) on 1 January 2025, according to the municipal-level data INE makes available.

A further table sets out nationalities not broken down above, among them Germans, Italians, Dutch, Belgians and Scandinavians, registered throughout Cádiz province. Unlike that earlier table, this one uses data from 1 January 2022, the latest edition with full nationality detail.

Of the 3,514 homes for sale across the province of Cádiz, the median works out at €2,220/m², with a median ticket of €224,000 in our data. That is below the €3,210/m² median across the 127 towns we track, making the province one of the more affordable among them. Half of the properties currently listed are priced between €1,550 and €3,070 per square metre, with cheaper and more expensive homes on either side of that middle band.

Based on €224,000, the median asking price in Cádiz (province), transfer tax at 7 % comes to roughly €15,700; add about €2,700 for notary, registry and gestoría costs and the total reaches approximately €18,400. This amount sits outside the mortgage and has to be available in cash before completion. All prices shown are asking prices from adverts active on 2026-10-05, not completed sales. The price eventually paid is always a matter of negotiation, shaped by condition, precise location and orientation.

The table below brings together the towns we track across Cádiz (province), listing inhabitants, foreign residents per 100 people and median asking price per square metre, to show how much these markets differ.

In 05/2026, Cádiz (province) had an estimated 15,116 tourist homes according to INE's experimental platform-based statistic, equivalent to 73,667 bed places and roughly 12 per 1,000 residents. The level is moderate, though letting a home to tourists still needs a regional licence.

The only commercial airport within the province of Cádiz is Aeropuerto de Jerez (XRY), so it is worth checking in advance whether it operates in the season you plan to travel, since schedules can vary through the year. Because Cádiz is where these climate figures were measured, other parts of the province, further inland, at higher altitude or on separate islands, can feel quite different. With a January mean of 12.7 °C (minimum around 9.4 °C) and an August mean of 25.0 °C (maximum around 27.9 °C), this is a mild-winter climate by any measure. Many residents manage with little more than light heating in the coldest weeks. With about 523 mm of rain a year on roughly 51 days, rain is neither scarce nor abundant here. Climate data come from AEMET's 1981-2010 normals, recorded at its Cádiz station around 5 km away; the actual spot may vary a little, particularly further inland or higher up.

18,439 home sales were registered in the province of Cádiz in the twelve months to 06/2026, according to INE. A market of this size usually means more comparable sales and a wider choice of homes for buyers. These figures describe the province of Cádiz as a whole and can change considerably from one town to another, and from one property to the next. Tell us what you are looking for and we will go through the numbers together.

The transfer tax on a resale home is set by each Spanish region. In Cádiz the general rate is 7 %, and on top of it come notary, land registry and gestoría (roughly one more percent). On a new build you pay 10 % VAT plus stamp duty instead of the transfer tax. This money is not lent by the bank.

When you apply for a mortgage to buy a rental property in Cádiz, the bank studies the same core elements as for a home you would live in yourself: your income, your existing debts and the property itself. Some lenders will also look at the potential rental income the flat or house could generate, while others prefer to base the whole assessment on your personal income from the United Kingdom alone. This is one of the reasons the study we carry out compares more than 20 banks rather than relying on a single one.

Because criteria differ so much, we never quote a fixed share of the price a bank will finance, nor a rental yield you could expect. What we can say is that Spanish banks usually ask non-residents for a larger deposit than they would ask a resident buyer, and that the exact share always depends on the bank, your country of residence and your financial profile.

Because you are applying from the United Kingdom, the bank will ask for the same kind of paperwork it would request from any UK-based buyer, translated into Spanish and sometimes apostilled. In practice this usually means your most recent P60 and payslips, your last filed Self Assessment tax return, bank statements from the last few months, evidence of any existing loans or mortgage commitments, and a valid passport or UK national identity document.

The exact list changes from bank to bank, and if the property is meant for rental use, some lenders may also ask for a projection of the income it could generate or for details of how you intend to manage the letting. We gather and translate this file for you and present it to the banks most likely to consider a buy-to-let application from the United Kingdom.

The price you agree with the seller is only part of the budget. If the home in Cádiz is a resale, you will pay the regional transfer tax (ITP), which is set by each region; if it is a new build, you will pay 10% VAT plus stamp duty instead. On top of that come the notary, the land registry, the administrative agency that handles the paperwork and the bank's valuation of the property, which the lender requires before releasing any mortgage.

If you ever sell the property as a non-resident, the buyer is required to withhold 3% of the price on account of your Spanish tax, which is later reconciled against the tax actually owed. Because you will be paying from the United Kingdom and receiving rent in euros, it is also worth planning for exchange-rate movements and the cost of converting sterling into euros each time you transfer money.

Owning a rental home in Cádiz does not end at the notary. As a non-resident owner you must file an annual Modelo 210 return, declaring rental income or, if the property is empty for part of the year, an imputed income on the periods it was not let. A local tax adviser can confirm exactly how this should be reported, and how it interacts with what you declare to HMRC under the double taxation agreement between Spain and the United Kingdom.

None of this replaces sound legal advice on licensing a property for tourist or long-term rental, which depends on local rules in Cádiz. What we do at Colibrí Finances is the mortgage side: comparing banks, preparing your file and following it through to completion, so that the financing is in place before you turn to the letting side of the investment.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
