I deal with engineers and builders every day.

Is this someone that we can see working with and making friends with at least 10 years in mind and we reverse engineer it from there to help as best as we can (i.e. if long term goal is to have a dozen buy and hold properties, lets work it in reverse from a dozen to just one deal and figure out how to financially meet the other 11 deals quicker)After spending this much time and building a superior relationship (connecting them with PM's, contractors, real estate attorneys, lenders, etc- whatever they need) it's pull the trigger time, and when there's a deal presented, they trust it's with them and only them in mind and it's a 'fit'. 

If wooded land, then loggers can put logging road exactly where engineers have subdivision roads going also to save some cost. 

Engineers are close to being finished with the preliminary plat.

I am an RN and my hubby is an electrical engineer and we are going to begin investing in real estate this year. 

Marketing is the engine that drives most any business.

I have engineered drawings completed so I can get the property rezoned and get my plan approved.

What is the algorithm/decission process that will take age, income, etc info into account?

While there I studied Civil Engineering, got involved in Engineers Without Borders, and picked up Rugby as my new favorite sport.

You will need to front the costs for engineering, plat map, going to a conditional use permit hearing maybe, having neighbors object, planning dept will have permit fees.
