Renting out a Spanish new-build: yields, licences and taxes

Buying a new-build on the Costa Blanca or Costa Cálida to rent out can work well, but the rules matter more than the headline yield. Spain regulates holiday rentals tightly and taxes non-resident landlords differently from residents, so the return you actually keep depends on getting the licence, the tax treatment and the running costs right from the start. This guide walks through what a buy-to-let owner needs to know before counting on rental income.

Long-term versus holiday rental

There are two distinct routes, with different rules and economics. Long-term rental (contracts of a year or more) is simpler: less regulation, steadier income, lower management effort, but lower headline returns. Short-term holiday rental earns more per night in the summer season but requires a tourist licence, active management (cleaning, check-ins, listings) and accepts seasonal voids. On the Costa Blanca and Costa Cálida, strong summer tourism makes holiday lets attractive, but only if you are set up legally.

The tourist licence is not optional

To let a property to tourists in Spain you need a regional tourist licence and registration, and you must display the licence number in every advert. The Costa Blanca sits in the Valencian Community and the Costa Cálida in the Region of Murcia, and each runs its own tourist-property registry with its own requirements (habitability certificate, minimum standards, registration before advertising). Letting without a licence carries substantial regional fines, and portals increasingly require a valid number to list. Confirm your specific municipality's rules before you buy, because some communities restrict new tourist licences.

What drives the yield

Rental return is mostly a function of location, property type and season. Homes within walking distance of the beach, a marina or a golf course rent more easily and hold value; apartments and townhouses on managed resorts are easier to let and maintain than isolated villas. On the Costa Blanca and Costa Cálida the season is long thanks to the mild climate, which supports shoulder-season bookings beyond peak summer. Be realistic: model occupancy conservatively and subtract costs before comparing to the purchase price.

How rental income is taxed

Non-resident landlords pay Spanish tax on their rental income, and the rate depends on nationality. Residents of the EU or EEA are taxed at 19 percent and can deduct allowable expenses (mortgage interest, community fees, repairs, depreciation). Non-EU residents, which since Brexit includes the UK, are taxed at a flat 24 percent on gross income with no expense deductions, under the Agencia Tributaria non-resident rules. That difference materially changes the net yield, so build it into any buy-to-let calculation, especially if you are a British owner.

The ongoing costs

Several fixed costs eat into gross rent regardless of occupancy: the annual IBI (local property tax), community fees on any development with shared facilities, home insurance, utilities during voids, and maintenance. For holiday lets, add management and cleaning fees (often 15 to 25 percent of rental income if outsourced) and listing-platform commissions. New-builds have an advantage here: modern insulation and appliances keep energy bills and repair costs low in the early years.

Why new-builds suit buy-to-let

New-build stock is generally well matched to rental demand. High energy-efficiency ratings cut running costs and appeal to guests, developer warranties limit early maintenance, and resort developments come with pools and amenities that lift both bookings and long-term tenant interest. Off-plan buyers can also sometimes secure a lower entry price before completion, improving the yield on the eventual rental. The trade-off is that you may wait for construction before any income begins.

Before you commit

Treat rental income as a plan, not a guarantee: verify the tourist-licence position for the exact municipality, model the return net of the 19 or 24 percent tax and all running costs, and get your independent abogado to confirm there are no community-statute restrictions on letting.
