I spoke with a Quicken Loan lender just to get a quick estimate of what kind of price range I was looking at for my first REI (also first home purchase).

Perhaps in the 100k range. 

Hi what are the HOT markets for cash flow properties in 2016,  when looking to stay around the 60-80k range? 

When appealing to a more picky rental market I use whatever is in style at the moment from the mid-range price-point in my area.

I'm waiting on the line of credit and searching for rental property #2; in the 30k-40k range after repairs.  

This business will make you very synical in one respect, you will be amazed at just how many theives, con artists, BSers, and incompetents there are in this business that prey on new investors ... and without any experience in investing under your belt, or way to validate out of state that you are getting what you paid for, you will surely come across more than a few, and each time it will cost you money (but at least you'll learn something).

I can respect their work.

They have ranged from 5% (now) to ~15% in the early early 80s and early 2000s.

I respect your diligence.  

This co-broke commission is in the range from 2.00% to 2.5%.
