That is a very open ended question. You haven't mentioned what you want. Do you want:
Capital Growth?
High Yeild?
Commercial?
Industrial?
Residential?
Land?
Many varibles. If you want Residential, then you need to consider whether you want a house, townhouse, villa, unit or maybe a block of flats. Do you want studio, 1bed, 2bed, 3bed? Do you want to buy & hold, flip, reno. Do you want standard residential or holiday/student accommodation? Budget housing or McMansion?
