I took the plunge into residential RE after I came into some money and the stock market seemed like a good place for part of it, but not necessarily all of it. I did a HUGE amount of research. The books recommended earlier are essential, as is Nolo's legal book for landlords (includes a CD with all their forms). The website MrLandlord.com is a great place to learn, and even to make some helpful connections.
I don't know how anyone makes a SF house cash flow, except perhaps by buying it at enormous discount. I bought a 2-family foreclosure, fixed the burst pipes, replaced the 2 boilers, refinished the floors, tiled the kitchen floors, new linoleum in the bathrooms, new vanities, installed carpeting upstairs, finished the attic - adding 2 more bedrooms, installed a much-needed fence (the yard ends in a cliff), and put on a new roof. Probably would have been cheaper to buy something in good shape!
I have advertised solely on Craigslist (free). I screen like crazy. I allow pets, and have only had one bad experience, which the security deposit has covered. I used VERY conservative figures for figuring the ROI, but even so I was astonished at how high a water bill can go with just one unreported leak!
I hold the property in a
LLC. I cash flow!
Since, I have moved to another state, about 1 1/4 hours from the property. I've had to hire people (a friend, my daughter) to show it when it was vacant this last time. I would sell it, except that it keeps making money and of course, prices are down! The tax advantages have been wonderful.
In the area where I live, rents are lower and housing prices are the equivalent or higher. So I haven't gotten into it up here. It's a possibility for the future, though, depending on how low prices go!
