Buying to rent is still viable ... but in another context and in another country.
France is the world's n°1 tourist destination and many UK and EU citizens buy holiday homes, gite complexes and B&Bs to cash in on the summer letting market.
There is usually a 8-10% return on investment and you get a nice place to live in for 9 months of the year as well. Prices are still falling in France (the Economist reckons they have another 30% or so to fall) so now is the time to start looking.
There's a number of specialist agencies like
gitesavendre.eu and
gitesforsalefrance.com which deal exclusively in these sort of properties - most of which are going concerns.
Or you can do what the Brits did in the 90's and buy up old ruins and barns, ferry down a gang of lads in a white van and do it all yourself. Either way, for less than €800k you could have 40 odd acres of land, 3 or 4 holiday houses producing a sure income stream and your own house to while away those pre-retirement years!
