Real estate interests me in all aspects but flips and income properties the most. 

I am now getting a certificate from zoning to show there is no commercial aspect to this property.  

Am I the one who ends up with the deed of ownership for said house and transfer the title for the investors or am I like a specter that simply puts the property in the investor's hands and disappears?

There are other groups putting out podcasts, forums, and groups for MHP owners and enthusiasts and you should check each out to find the ones that seem to address your needs.MHP's are complex animals and it takes time to get to know all the different aspects of them.  

Not an insurance agent but i believe the difference is, the Vacant policy covers the existing structure plus improvements as they are done. the builders risk insures the material and i believe aspects of the project as it is built, since there is no structure. so if you happen to take a builders risk and you are doing reno, it may not cover you for the existing structure .

Actually, it would be better to ask a finance type attorney, notes aren't real estate but this is a basic business contract aspect.

We have great programs for every aspect of the real estate cycle including cash out refi's with only 30 days seasoning.

It might be something to look into, as long as you think about the different financial aspects of any of the potential deals. 

It doesn't matter if your a retail flipper, wholesaler, landlord, property manager, realtor, lender, or any other aspect of this business.  

Kind of guide me through certain aspects of this RE game.
