This job took us about 9-10 months if I remember correctly.

The technicals (migration rates, job growth, tax situation, debt cost, etc) to work as well.

Has the tenant been looking for a new job?  

Keep in mind though along with rehab the turnkey operator is paying all the holding costs generally most if not all turnkey companies use HML loans for their inventory ( thats my Job) and paying taxs insurance utls etc.. so you need to add 10 to 15 on top of the all in for holding costs..

However, even though they both have jobs now, they still do not pay the weekly rent that they promised to pay.

Reason: I signed a new job offer at a nonprofit yesterday and having extensive knowledge of the real-estate market in Philly would be very helpful.

For instance we have seen dozens of sand and stain jobs on hardwood at $2/sf that needed to be completely redone. 

It seems that to be on Section 8 you need to look for a job on a regular basis.

Vitaliy, gave you solid advice and did a good job of explaining some of the key issues.
