That is worst case scenario and most reputable HML don't want the property back. 

The plumber that came to repair that said that leak had been going on for a while… The funny part… They had the hot water heater turned way down (I turned it up which is probably what helped us find the issue).

Avoid building a reputation as the guy who never closes. 

It's very similar to calling in a plumber to fix something except you just have a bigger list of things.

Right now though, if I'm able to work with investors (friends and family who know me personally and trust me) who are comfortable with unsecured loan then I will definitely use it as I start building a real estate reputation and create a track record of putting deals together.

I'd say focus on people first and foremost because if you go with a reputable team with a good/long track record, you know the market supports their business, so its a little bit of built-in market vetting (though certainly not the limit of the research to be done). 

While there are some reputable marketers out there, it does mean that you need to do one more level of vetting - vetting the marketer (the people you buy through) AND vetting the turnkey company (the people you actually buy from and work with long-term).Generally speaking (and yes I am biased here) I recommend working with the turnkey provider directly if at all possible.

I would recommend contacting a few companies, then go with someone reputable that has cost in the median range.

@Angel Bowers I haven't owned there but it does have quite a reputation.  

While working with wholesalers can be beneficial (I know a many respected and reputable ones) an inexperienced wholesale practitioner can be a major detriment.
