Thank you for your awesome service.
I have bought properties in "Crappy areas", and in good areas. I will say the "Crappy areas" often yield good cash flow, but you work your butt off, and have regular problems. "My wife, she. My dog, it." The return may be acceptable, depending upon the cash flow and how many midnight calls you can handle. I have hired property managers for the crappy ones, but that is a problem, too. The good ones don't want the bad ones.
@Judy Parker is correct on another issue. When you buy "crappy", your exit strategy is usually to another shark investor.
I think the ideal portfolio is a few properties that throw high cash flow (crappy), a very few that throw negative cash flow (you think they may have appreciation potential, and you bought for nothing down) and a bunch of bread and butter 3/2's in good neighborhoods, that throw moderate positive cash flow.
I guess it depends upon how much you have to pay. I generally buy low-end for almost nothing.
I like @Joe Villeneuve ending to his emails. I don't have enough money to afford a "regular ending", but I often say, "I would rather lose sleep over the one I didn't buy, than lose sleep over the one I bought."
Again, many thanks for your fine service.
