Polyethylene (PE) pipe (black) is best to use underground.

I don't yet have the property under contract and did not want to spend the money on a PE.

You can look up active licensed civil/structural engineers by going to the TX board of Professional Engineers website. https://engineers.texas.gov/roster/pesearch.htmlNow, keep in mind that not all civil PE are the same... sub-disciplines of civil engineering includes engineers who specialize in material science, coastal, earthquake, environmental, water resources, geotechnical, structural, transportation, etc... 

Last I looked PE ratios were a little over 20, something like 21x's earnings.  

I think I’m going to get a signed structural report by the PE and show it to the borough, either they tear it down or I take them to court.

However, it is still a small percentage being acquired by REITs and PE Firms in comparison to the overall housing stock.I would say the tremendous quantitative easing we have seen and direct stimulus to individuals has caused this more broadly than simply pointing the finger at Wall Street.

Who, what where , etcI then learned the gigantic world of PE (private equity ) and family offices and the vast amount of cash they have.

I've been investing in RE and PE funds / syndications for the past 7 years.
