New Construction In Nassau County Long Island

[Nate Brown]

Hello BP!

I have the opportunity to purchase a subdivided lot in Nassau County long Island. The lot would be ideal for a modest 1,500 sqft, 3-4 bed/2 bath home. The owners have agreed to sell me the lot via Seller Financing. The deal is contingent upon the Village's approval of the subdivision and construction of a new SFR. I've met with an inspector with the Buildings department and he affirmed that the lot could be divided. My plan is to wholesale the deal to a builder. My questions are:

1- Should I secure written approval for the split & construction prior to presenting to a builder?

2- How much would it cost to build a new 1,500 sqft, 3-4 bed/2 bath house in Nassau County?

3- Has anyone ever closed a similar deal? If so, what advice would you be willing to give?

I want to thank everyone in advance for reading my post and answering my questions.
