I have experience in many other fields including residential and commercial construction, surveying, heavy equipment operation, civil engineering design, and I was also a project manager for my current company.

I used their book to do a number of exchanges to help my friends and engineer my win exchanges.

Its about value these days for the search engines. 

In commercial, I rely on experts, engineers not home inspectors, Realtors, attorneys and accountants, all are bonded and insured, if they screw up they can pay for it, it's different than residential but the due diligence is much different too.

First, read what @Jeremy Tillotson just wrote.Second, I will ad this to his 2c...Reverse engineer your offer from your comps as follows:1 - Start with your comps2 - Subtract your profit (if there's no profit, why bother).  

The key isn't just to have on, the keys are to understand the difference between a plan and a concept, and then how to build it.You start by using reverse engineering, and with a need/opportunity.  

I’m looking for a Cost Seg Engineer.

You will need to get a civil engineer, land planner and land use attorney involved.

Find Structural Engineer to come out to inspect damage and advise a course of action.I only have a few days after the inspection period to respond. 

As an engineer, I can't help but look at risk in a simple format.. just google "risk assessment matrix" and in there you can evaluate the cons and pros of your risks and consequences.
