. - I've noticed that the sweet spot for purchasing cash flow properties is in the $50k - $75k range.That's a pretty broad price range to be considered a "sweet spot".

You don't phrase it quite so directly, but that's a topic that's broad enough to have its own thread—in fact, I'm sure there are already several in the forums.Good contractors are hard to find, and that's who I would look for next.

It just takes a lot less thinking effort to paint areas with a broad stroke for some. 

Your request for suggestions is somewhat broad.  

I live in the city and like s philly along the broad st subway.

Cheryl -There are really no hard and fast rules about the difference between retail and investor pricing (and it really is a spectrum, not just one or the other).Here's how I look at it (all numbers are completely made up by me):Imagine an electrician who wants to work full time (2000 hours/year) and wants to make $100K per year.

Also if you have no idea what your niche is I recommend you read "the beginner guide to real estate investing" on Biggerpockets its free and it gives a great broad overview of all the methods to make money in real estate.

IMO your scope is too broad.
