Next is usually builder because they are likely listed on permits etc.   

I have talked with a number of builders in Florida,  who like to keep some of the builds they do to get steady cashflow.let me know if you ever want to talk about how they are doing that 

Has the agent spoken to the builders in the area who may need lots?

You'd have to be a builder to really reap any sort of profits from an area as such. 

I bought the land and my builder buddy is putting it up at cost we plan is to hold or maybe I buy him out.  

You should also look into Jacksonville Wealth Builders. 

I think what attracts builders to the larger resale companies of which there are at least 10 that do what RTR does is these companies Will focus on their product they wont show your product and then sell something else..

I found working with investors from around the country it is much easer and safer to let builders do what they do best and I will stay on the investment side.  

Every one of them has switched builders and every one of them is having problems with the new builder.

I still have other builders build for me too actually because of bandwidth.
