Do you have enough spare to invest in a second property for buy to let? Usually 30% deposit i think is the requirement?
Then buy a flat in a city centre, either Glasgow or Edinburgh and rent out to professionals. To put things into perspective, I know someone that bought a £170k flat in Manchester City Centre. and the agencies valued the rent at £1700/m
. Granted, it is bigger than your average flat at 1000+ ft, and space is normally a premium. If you can find a gem like that then it makes a good investment.
