Looking for an option to build an ADU, future development in the area and on the land.

My worries are that following through with the wrong subdivide while in the county will affect my greater plan of rezoning and developing Parcel (B) after annexation with the town. 

For ground-up inspector spec or builder development, we're usually topping out at 80% of cost (land plus construction plus soft costs) up to 70% of As Completed Value.

I am working on the feasibility of a joint venture multifamily development. 

Hey Jack - Have a development project in vandenberg village, have done a couple of flips in lompoc.

@John N CookIf you have $200K + in retirement funds, other capital, experience with construction, and want to explore creating a real estate development company doing 3+ flips or spec homes per year, check out a ROBS.  

In this way you are always growing and developing. 

My ultimate goal is to develop land once I have enough passive income and financial freedom.

So the current owner bought from the developer when the property was 3 years old then?

You can take a look at its economic development site to learn more on it.
