I recommend picking a market where you have a "competitive advantage".I am from San Diego and have lived here my whole life.

If you wanted lots of potential rent growth and appreciation, and don't mind competition from other investors, I would look at East Walnut Hills, Northside, Norwood, Madisonville maybe Camp Washington.

Marion oaks has become harder to rent because of the amount of competition but I like it for long term because that is the side of town with the most growth.  

Sale Price vs List Price shows a stable pricing market indicating no major swings in pricing competition.

Another issue is simply more competition.

This is an excerpt from his email:Clearly, we're not competitive with what you're paying now.

Also, in my market to be competitive the houses need to be furnished (and not with crappy stuff from the side of the road), and you need to at least provide dinners during the week (which presents it's own logistic difficulties and cost difficulties).

Sheriff sale properties usually have a lot of competition for the good stuff, guys and investment firms with deep pockets.

Prices are lower, there's less competition and likely less sharks. 

I achieve more than adequate protection through the responsible acquisition of liability insurance property specific and umbrella, and I do it at a tiny fraction of the cost and hassle that an array of LLCs would cost me.
