The most important thing that I can suggest to you is; Go over and above board with your due diligence. Getting clear title should be your number one concern. Also, have the lots been partially dev. Utilities, pads, etc? If so! chances are the property taxes haven't been paid in a while. What stage of development are these lots in? What liens or changes in demographics has the city made-if any? Go to city hall and talk to the city planner if you haven't already done so. Buying raw land in a emerging market to resell to developers is one thing. But Pre-developed land is extremely risky unless you do your home work. Also, one more thing! Ask the city planner if any Contractors and or developers have recently inquired about those lots. If so, get their number and pick their brain and maybe network with them. I'm currently working on 4 REO lots right now, What I'm finding out is exactly what I'm saying here. Good Luck!!
