Hi GalwayBoy,
Thanks for all that, that's really useful information. The sum would be made up of 70k of a deposit, the rest a mortgage. I would be looking at a 2 or 3 bed flat. I lived in Germany for a year during college, so it is somewhat familiar to me. And it seems like Berlin is a good place to invest in right now, as you say teh majority of people rent so it's a good renatl market. I have a younger brother currently living in Berlin (doing the music thing!) so either he could live in it or look after getting it rented out.
I'm just gathering information at the moment, so I do not have a particular property in mind. Are you aware of any locations that you feel would be particularly good to invest in right now?
