Sounds like an excellent system you've got going. As you said, you wouldn't want to make any gross misjudgements, but hell, what's your worst case scenario - you cant rent it out and cover your interest? Then just sell it. It seems like an excellent return for fairly limited risk.
Anyway - I dont want to get too personal, but do you do this full time? By the amount of dealings you do, it seems like a full time job. How do you find so many willing to have a delayed settlement?
