MTR and Section 8 are very different niches with little in common so it's very difficult to provide advice on your question.

We are planning to occupy there for 1 ~ 2 years and looking for cash flow after we leave. 

You could however at any time do a cash out refinance that will help you pay off the heloc as you said.  

Is she licensed to provide property management in whatever state it is?

@Cameron KlosterLooking for cash flowing assets.  

Once the property is rehabbed you can look into a DSCR loan to cash out on the new appraised value.

You can skip trace the addresses using a tool like propstream as mentioned, give them a call and ask them if they'd be interested in an all-cash offer on the property, don't get into the fact that they are behind on payments, just ask them if they can use cash fast.

I think it is better to connect with many GCs, find the ones you want to work with the most, and have them walk properties and provide bids for you.
