I would probably find another engineer.

Hello BP,I've been working as a Gov contractor providing Cloud Engineer services for a while, but my true passion is commercial real estate.

The buyers had a structural engineer inspect and then asked for another $60k reduction to stabilize the foundation.

I am an engineer so I am very used to Excel.

@Ryan LudwickStart your real estate investment journey by leveraging engineering skills to analyze markets, spot trends, and build a team.

You can determine what a decent salary would be for someone in your market and then reverse-engineer to see if what you're paying as a salary, plus the projected performance commission, will get you there.

Go to google and put the name of person / entity you are interested in the search engine, and then add the words "and scam".  

I am not your structural engineer so take what I say (and others most likely) with a grain of salt and best to get a contractor to come take a look at it.

Reverse engineering. 

Lawyers, engineer, architect, expeditor, surveyors, etc pile on the fees quickly.
