I can't speak on the BTL market, but I visited there recently to find that the whites (currently make up most of the professional classes) do not live in the city for the most part and prefer to commute from the suburbs and neighbouring areas where they have more security. Those I talked to were quite fearful of their future, so if you do buy there you would have to do some deep thinking about whether you will be able to sell in 15/20/30 years.
