so uni, you buy a studio/bedsit (not sure what else you can get for $150k) and rent it to a student.
because it is less than 50 sqm you must stump up a higher deposit. also other costs would almost certainly be higher than $2k even if l assume you manage it yourself. can you provide a link to such a goldmine? i'm in SA, one in adelaide would be nice. but if you want to go interstate happy to open my eyes to these "opportunities".
