If you fail and lose their money, you lose your reputation and reputation is everything, at least in my book.

I researched on Zillow and found a great agent with a great reputation and today she reached out for me to the seller's agent about the building and its status. 

I'll see if their reputation precedes them here locally.Your odds of recourse on this situation are unfortunately very slim.

All reputable firms

Definitely quality answers from reputable people, but the one thing that wasn’t mentioned and I think is crucial with regard to aspect of time, is sourcing assets.

With a manufactured home, for flip purposes, would you go with laminate or hard wood? 

Seriously listen to @Michaela G.Everything that I've been taught about credit history is spot on to what she's saying.If you go and pay off the amount it will become recent history and carry more weight than just leaving it alone.If you're going to do anything, speak with a reputable credit repair person.

Could anyone recommend reputable turn key investment companies? 

I put 8 smoke alarms in my single-family rental - Lowe's sold a 6-pack of the model I used, and then I bought two more of the same model individually.Also note that if wired detectors are required, they may not all have to be exactly the same model, but they do probably all need to be from the same manufacturer. 

With none my own lenders, contractors, or reputation to draw from, for the first time, I had to ask for loans from family.
