We try to warn our buyers about this and to use one of our trusted resources that is normally local, in the business for years, super knowledgeable and has a local reputation to defend and maintain. 

Definitely read all their reviews, see how they communicate and look into the company's reputation. 

Make sure that that is a reputable person.

Focus on building strong relationships and networking in your local market—having the right connections and a solid reputation can open doors to opportunities that don’t require perfect credit.

Thanks Mike, yeah NM has a Walter White reputation now.

Find a reputable roofing company-look at online reviews and find one that has been in business for a while...ideally local company.Inspect the roof-are shingles curling? 

Reach out to the resources provided and reputable community leaders.

We have to keep in mind flippers have a bad reputation of doing the bare minimum and making loads of money (which we know isn't true).It would be hard for me to recommend remodeling it without spending more time on it.

It sounds weird, but you have to be careful how much you advertise so that you don't get a reputation for being "out of money", while at the same time networking with wealthy individuals/family offices/private equity.It's a little different if your approach is going to be only loaning your own capital.

My advice would be try and find a reputable investor friendly Realtor in the area 1st and foremost.
