I know you mentioned you are looking to flip houses yourself in the BHAM market. 

When I was going through the mortgage property the loan processor (didn't really seem like he knew what he was talking about fully) mentioned I can't put the house in an LLC because its an FHA and it might make the loan Due on Sale?

I have heard from few tenants that during their tenant onboarding they clearly mention tenants can pay the difference but when it comes to landlord they state something else.

Those services you mentioned are terrible for vacant houses for the reasons I mentioned in my post.  

Here is one template that might generate some ideas;Deal- Property Type- Property Location- Market Metrics (as @Joseph Firmin mentioned above)- Scope of Work (both what qualitatively will be done and the corresponding $ amounts)- Exit Strategy (Sale, Refi)Borrower(s)- Borrower(s) experience (focus on relevant project experience)- Personal financials (as @Joseph Firmin mentioned above)- Additional info

Many people mentioned that it is strongly recommended to have a CPA as a part of the team. 

Or does he need some flexibility with closing timeline (like you mentioned). 

I heard a podcast mentioning a company that specializes in this called Super Hog.

I see a lot of posts mentioning DSCR loans, but if you're buying a primary residence, a DSCR loan cannot be used. 

But I believe that's what Bill Gulley mentioned doing that.
