"If you really know your market and have done a lot of homework you could work with the risk and make educated decisions, keep costs low, I agree, like UT, however that appears to be close to a full time job. If your full time job is property, then you should be good at it. "
Actually for me it is not a full time job. I work full time, manage 3 properties and other business interests. Generally the properties do not take up that much time at all average of a couple hours a week really. The most time spent will be getting a property going in the portfolio.
