Investment Properties That Aren't

There was an ad for a 2 bedrooomed aparment in St Martini Garden's advertised for sale. Asking price R1.595 million with a tenant (until September) paying R4950. Now if you bought the flat for that price and put in a new tenant at that rental what kind of investment returns are you looking at?

3% ROI with nearly a 100% deposit? Ouch.
