I don't have direct contact in the Acquisitions department as I work with their environmental due diligence team on Phase I Environmental Site Assessments.That said, I echo @Chris Martin in warning that the environmental and engineering feasibility process can easily take a year or more.  

Obviously, a complete and well built website with interactive components and quality information that’s constantly update and optimized for particular keywords to show up on the first page of search engines (including YouTube) will bring in the MOST valuable leads.  

Is the risk for a developer that they're paying for the engineering work for something the village/govt won't approve? 

I've had to hire Real Estate brokers and Professional Engineers (PEs) as "expert witnesses" for defending various false claims.Regarding #3, the smaller your project, the less likely you'll see high impact study costs.

You need to find architects/engineers in your market that deal with this type of project.In my mind, I would like to know what the per unit cost is of each unit.

Every jurisdiction is different, but in general it's usually a civil engineer and/or architect and/or general contractor who can give you an idea of what is feasible. 

Hi @elisha  I am a land planner working for a civil engineering firm in Alpharetta.

An additional benefit of a detailed engineering-based Cost Segregation Study is that it can increase potential insurance premium savings as well as provide support for the property tax appeals process.

They are engineering those returns by over raising equity.  

The best route is using licensed foundation companies and engineers to conduct work surveys to determine what needs to be done and then having that work done by licensed companies with warranties.
