Spain encourages buy-to-let investors - Telegraph Another boost for foreign landlords will be tax relief on the rental income, ranging from 60 per cent to 100 per cent. But this is based on the proviso the home is rented to working people under 30 years of age. The new rules will also replace the existing inflation-linked rent increases with agreements between the landlord and the tenant instead. The improvement in Spain's buy-to-let market and plunging house prices could present a good opportunity for Britons living in Spain to buy for investment in areas they are familiar with. Data released by Spain's Ministry of Development show foreigners bought 12 per cent more properties in the second quarter of this year compared to the same period in 2011. Alicante was the top buying destination followed by Malaga and Barcelona. Marc Pritchard, sales and marketing manager at UK-based housebuilder Taylor Wimpey España, said the sharp fall in property prices was the main driving force behind the increase in sales. He said: "Spain still ranks top of the list for property buyers. For Brits the easy-to-reach reliable good weather plays a big part, swapping grey clouds for blue skies. And the strength of the pound against the euro means that visitors can get more for their money.
