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. 

Then determine which areas fit cost:rent using your accepted finance model Then run an algorithm on those areas to determine viability.  

The designation for Certified Cost Segregation professional is CCSP and comes after the engineer’s name.

Check with the building permit department about exact submission requirements and what work requires licensed designers and engineers.

They just buy stuff they think buyers will like.How to reverse engineer the purchase price to earn a profit.

Agreed Bob maximizing the contract amount is half of the algorithm, and if you know how to do that then you're golden.
