I've worked in most phases of residential construction, but have not yet managed  a project this large.  

Her mother is willing to (co-sign) and has excellent credit and debt to income ratio that will more than allow but I’m not sure the best way to structure this for the house to still be in our name?  

I went to the company website and signed up as a potential investor.Got an automated welcome email from Sunrise partner, Brian Spear, which asked me to read the fund's PPM and schedule a phone call with him.

Or even a contractor that does large additions and then move towards ground-up stuff.

There are large areas in the direction of the flight paths that do not have dense populations so it’s mostly a non-issue.

Quote from @Stephen Schmitt: Hello Dwight, I have an excellent PM I can recommend.

Here are my two cents...I recommend starting in a market with strong fundamentals, such as steady population growth, an influx of major corporations or large businesses relocating to the area, an affordable cost of living, and high rental demand.

Some ways to find that person is local Real Estate Investor Facebook groups, local Real Estate Investor Associations, Realtors who list multiple properties for other investors, Bigger Pockets website's forum, and local property managers.You will also want to try to get on the buyer's list for local real estate wholesalers.To Your Success!

This is a unique home and it actually has a full kitchen, 2 bed and 1 bath downstairs and I think it might be well suited as a very large vacation rental(entire home) or both floors being rented separately at some point in time.  

Also, if anyone has any experience in land purchasing I would appreciate any tips or websites on how to find the best deal or agent for the same.
