No building suggestions for you, but just a thought... although the condo prices can't be beat, I would be a little nervous about buying an investment condo without some heavy duty due diligence. A $150,000 condo sounds great, but I've seen some where the condo fees are from $750 to $1500 a MONTH.
Also look at purchase dates of other units in the building... recent (5-7 years or so) probably have a higher chance of defaulting on their mortgage should they be upside down, thus the condo fees could be raised should more people vacate.
Just some food for thought... good luck to you
