I found Bigger Pockets about 3 years ago, so you could say it's been a long time getting to this point, although it's mostly due to analysis paralysis and failure to take action sooner on my part.

Coils, blower fans etc, and it is the number 1 cause of HVAC failure.

There is something to be said for the quality of fire lit under your a$$ when operating without a Plan B.I also concurrently believe that many people who do not allow for the possibility of failure in their lives are suffering from a cognitive dissonance and when they do fail, the failure breaks their minds and they rarely fully heal in the broken places.I believe consistently successful people have a dark and secretive cynical part of themselves that knows when they're cheering themselves on in a limited way to complete a difficult task and when they're lying to themselves.

Failure to use a licensed company can cause BIG fines.

I also assume there’s a written penalty on the books for failure to disclose these are all things I hope you r realtor can answer instantly and 100% confidently. 

Depending on how many you go through, heaven help you if you have that, in addition to a major expenditure (i.e HVAC failure, roof) For people with not great cash flow, you wipe out yearly profits every time.

people get great joy talking doom and gloom and Armageddon.I’ve been in the RE biz since 1978 and been thru several economic and market cycles.Stagflation in the 70s, 17% home loan rates in the early 1980s, the failure of 1/3 of American Savings and Loans in the early 1990s, the dot com boom the dot com bust, the subprime crisis in 2008, Covid………I’m probably forgetting a few.

It is legitimate....and while yes the failure rate is 90%, I bet its higher for wholesalers.  

It looks like you are buying someone else's failure.

Failure to follow instructions?
