@Caleb: things are going well so far, but it's a mixed bag. I have one house doing great in Dayton OH. My Detroit house has been hit with a couple of massive unexpected bills ($6K and $9K) for lead water pipe replacement, so I'm never investing there again! I'm selling my two IL houses (one is under contract) which was always the plan. I wanted to convert my Windsor NY house into a duplex which would have been really fantastic for revenue, but the council refused zoning. That was disappointing because no external changes were required to the house. I had a great renovation planned for my Poplar Bluff, MO house, with financing lined up, but it fell apart because we couldn't find a good, available contractor after several months.
So overall, getting into real estate has been a fun, frustrating but hopefully worthwhile pursuit. I haven't made great financial progress this last year. However, I now have everything in place, I've got a lot more practical experience and contacts, and haven't lost money. So hopefully onwards and upwards!
