The question is why develop a park when you can buy a functioning one for less $ per lot and with positive cash flow?

Thank you for the advice and feedback!

@Christopher Blanco - echoing feedback from above, it seems like there a few areas your contractor may not have a lot of experience and/or may have estimated high without contacting the subs to get accurate estimates.  

I have talked with other people that have used Renters Warehouse as @Chase Keller mentioned and I have heard nothing but good feed back. 

Some help would be appreciated so I can plan and position myself!

This is important because, in theory, you are only buying homes that have positive cash flow.  

Does anyone have any positive or negative experiences purchasing homes from an investment company which they rehab, screen tenants and property manage in another state?  

Maybe give person B a second position behind the main mortgage on title? 

I appreciate any and all feedback.

All the feedback you've received thus far is great.
