I have 17 with number 18 just put under contract.My first 8 or so were either fringe areas or houses in poor condition.Those 8 are about 3 times the trouble the last 9 are whenI was able to switch over to better product (areas, house layouts, and my rehab levels).From the sounds of it, you were much smarter than I when you started and limited yourself to the nicer areas and better houses.I'm doing 17 now and its running extremely smooth.

Excellent plan.
