Need advice of new construction/ subdivision

[Elizabeth Anderson]

Hi everyone I'm Elizabeth Broker in Charge of my small company. I'm seeking advice on how to structure a  relationship with a  residential home builder. I currently have several clients who have listed their vacant land with me. One of my clients wants to start a subdivision and I have found a builder who say he can do spec building on the lot. He gave me the explanation of spec building; but I wanted to get more information from a realtor who have done these types of deals with spec building. I reached out to a few agents via phone in my area put they all seem to be tight lipped about the process flow. If any one can share that would be great.
