Buy to Let in Spain, madness or not?

[cashmax]

I have a good friend and he and his wife have just sold there house and will be left with around £350K. They want to rent in the uk and buy a property in Spain in the Alicante area. They have been seduced by the agents out there and promised a return of circa 20% on the investment, with them spending a few weeks out there each year.

Sounds like an accident waiting to happen with Brexit effect unknown and lying, scamming agents everywhere out there.

Anyone have property in Spain that can give an idea of the pitfalls and the real world returns?

Thanks for all the replies. I pointed the friend in question at this thread so they can see for themselves. The problem is that there is so much propaganda on the web from the involved parties, to the untrained eye, a quick Google tells you it's a good thing.
