You don't want to bet on appreciation due to a good school neighborhood.

I do buy in C- or D plus areas (I try to buy on the fringe of these areas, so next to a highway or the corner of "the hood") , so in large part my properties won't appreciate a great deal, they are strictly a cash flow play and I intend to keep them forever.

C or B class areas between 1000 to 2000 sqft.and if it is not gutted than it is better, but I think I can handle with a gutted house also.

Do I file schedule c or 1120s?

When you started with both of these brokers they should have already of known that COR's were on hold. 

Hindsight's 20/20 and if you're certain about the future then go bet on it, but any advise on current rates and the talk about the FED raising them?

Class A,B,C or D?

Shaye Mora If you are achieving 2% or better in the investor-friendly states these days, it probably comes with higher vacancy over the long haul and/or is C- or D-class.
