Is a Renovation Investment in Spain Risky? An Honest Look

Anyone researching a buy-renovate-sell project in Spain deserves a straight answer rather than reassurance. Renovation investing carries real risk: building surprises, permit timing, and a property market that can move between the day you buy and the day you sell or let. None of that disappears because a project is managed for you.

What follows draws only on facts we can stand behind: our own group has bought, renovated and resold 18 homes for investor clients since 2022, with a median renovation budget of 22% of the purchase price. These are past results, recorded in the group's accounts, not a forecast and not a promise of what any future project will return.

The risk in a renovation investment rarely comes from a single dramatic event. It usually comes from small, cumulative surprises: a wall that hides more damage than expected, a permit that takes longer than planned, a local market that cools while the work is finishing. Anyone telling you these projects are without risk is not being honest with you.

Our own group has completed 18 such projects since 2022, with a median renovation budget of 22% of the purchase price. That figure is useful context, drawn from our accounts, but every property is different, and results on any single project can be lower than hoped, or negative.

Once a wall or floor is opened, a renovation can reveal issues that were not visible during a viewing: old wiring, damp, or structural work that a survey could not fully anticipate. Permit fees, gestoría costs and materials can also move during a project that runs over several months.

Using our own team of renovators, rather than subcontracting each stage separately, gives us direct control over quality and sequencing, and lets us flag problems early. It does not remove the possibility that a final renovation cost differs from the initial budget; that risk sits with the property, and ultimately with you as its owner.

A renovation project typically spans months, not weeks. During that time, regional transfer tax rules, demand in a given area, or the rules on tourist rentals can all shift. A licence that was assumed available when you bought may need a fresh check before you actually let the property out.

If the plan is to sell once renovated, the eventual sale price depends on the market at that later date, not the market on the day you bought. If the plan is to rent, income depends on demand and, for short-term lets, on a valid regional licence, which is never guaranteed in advance.

Because the United Kingdom uses the pound rather than the euro, exchange-rate movements and conversion costs affect what you actually pay when transferring funds to Spain, both at purchase and later, for renovation costs or on-going bills. It is worth planning transfers rather than leaving them to the last moment.

Spain and the United Kingdom have a double taxation agreement, and a local tax adviser should confirm exactly how rental income or any gain from a Spanish property must be declared to HMRC, alongside the Spanish non-resident return (Modelo 210). When you eventually sell, the buyer withholds 3% of the price on account of your Spanish tax, and a separate municipal capital-gains tax (plusvalía) applies on the land value.

Using our own renovation team, rather than a chain of subcontractors, is one way we keep closer control over quality and timing. We also carry out checks on the property and coordinate with your lawyer, notary and bank throughout, so that legal and financial steps move at the same pace as the building work.

What we do not do is promise a result. Fees are agreed and paid for the service; we never pool investors' money, and this is not a fund. On residence, the Spanish Golden Visa ended on 3 April 2025 and is no longer available; as a British citizen you can stay up to 90 days in any 180 without a visa, and would need a visa or residence permit for anything longer.

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.
