I'm looking to do what you have accomplished - get my first duplex and house hack it.

Raise the $600K, do the pre-development work, then “sell” the property to NewCo.  

We want to do this transaction so we can upgrade our living space, have another rental (our existing house), and eventually rent out the new house (his house) after we grow out of it.

Some context, I have 3 other properties in a different city and am currently on 1099 income (so I can't do conventional) for the past 3 months.

I do my best to be the intermediate between the consumer and the seller, simply by bringing awareness to a buyer's potential.

How do you find information on homeowners?

While I think neighborhood farming is a good idea, I'd say instead of doing it geographically, think about who is most likely to move in your community. 

Land trusts can be established the day before closing and do not require state filing to create.

Thanks  Ask them if they have a NMLS number. if they do not they can only make a DSCR loan for you.

Have you looked into what similar rentals in your area do?"
