So my question is I would do a land lease to the builder.

They are in partnership with Obie for Fix & Flip type insurance (builders risk, etc).  

I have a small residential interior design business serving home builders and residential contractors in Northern VA.

What I've heard through them is as follows: The student body has changed drastically over the last 10-15 years.

It is improving, meaning sellers and builders are facing a little more competition, but there is still a shortage of housing units in the region. 3) Rental prices are strong and single family homes and townhouses rent very quickly.

First step would be to talk to the controlling government body about what you can do with it.

Then I wait for their responses and see their body language. 

Who was the builder of your DADU? 

I know a lot of builders up there, but not very experienced with the flipping model.

I trained and set up the same type of seller financed side for the largest home builder in the state.
