In the manufactured home industry, I've heard more complaints about new homes being bought and installed straight from the factory than consumers buying older homes direct from homeowners. 

What no one has yet mentioned is the movie industry.

While technically negotiable, the Sitzer/Burnett case revealed that the industry practice effectively standardized these rates.

Do you think its helpful & necessary for upskilling teams or is the industry not in need of it?

True, I am 100% with you on that.The point here is, when you analyze, you do based on what you know now (what is known as a fact today) and on what is highly likely to happened (again from today) and to accept the fact that things might change tommrow.Life happened every day, that’s why  we need to stay firm with our direction but flexible with our approach.having lived through the HORRORS of those years fully engrossed in the industry almost nationwide... it was regional on who did well and who had troubles.. no question well positioned landlords in Portland for instance no issue.. 

See the chart from Fair Isaac Company (FICO) below: FICO Score Pct of Population Default Probability 800 or more 13.00% 1.00% 750-799 27.00% 1.00% 700-749 18.00% 4.40% 650-699 15.00% 8.90% 600-649 12.00% 15.80% 550-599 8.00% 22.50% 500-549 5.00% 28.40% Less than 499 2.00% 41.00% Source: Fair Isaac CompanyAccording to this chart, investors should use corresponding vacancy+tenant-nonperformance factors of approximately 5% for Class A rentals, 10% for Class B and 20% for Class C.To address Class C payment challenges, many industry "experts" are now selling programs to newbie investors about how Section 8 tenants are the cure.

Here’s, the hard truth I’ve found in 45+ years in the industry; the vast majority of real estate investors, practitioners and business owners do not have a scalable activity.  

I started STR to offset my W2 incomes and found how easy industry was and focused last 2 years on it. 

It is the most popular software in the industry and all CPAs know how to navigate it which is nice.

I've been doing a moderate level of research around the housing industry and I am very excited and eager to jump in.
