Would love to get more involved in investing in the great state of SC.

Additionally, involve a real estate attorney to ensure the transaction aligns with legal requirements and protects both parties’ interests.

Then involve a GC once you understand the scope of work.

I was involved in two small infill developments in Michigan (about 15 houses in total) so two very small parcels. 

The founder appears to have been involved in businesses outside of real estate: ‘My dream is a locally made grooming products business’ | People | nashvillepost.comSo it does not appear there is a lot of track record there, but those are questions I would ask.

Because buying a house in excellent condition and then totally changing the layout can be expensive, especially if it's involving load supporting walls. 

If they are making so much money why are they not being responsible to do what they say bi am shocked so many people involved in this but I am not alone.

Now more than ever, I am seeing offers required to be submitted through a portal where the listing agents want no business being involved with up front negotiations.

It's just not a subclass I want to be involved in, but perhaps you can make it work for you! 

I think if you are going to keep all three parties involved as owners of the deal long term then you need to separate yourself as a renter and a contractor.
