We have learned the right and the wrong way to conduct our self and recommend all investors, agent, brokers, and negotiators do the same.  

I sat down in the conference room, and listened to numerous conversations between investors.

This is an "ad platform" model, and the one many project-driven issuers are using as it is exempt from all regulation (the offerings themselves still have to comply with SEC rules and state securities dealer laws, but the portal itself is free from oversight so long as it conducts business legally).There is a lot of internal industry debate about which is the best and there is disagreement among securities attorneys knowledgeable in the space about what is required.  

Likewise another would be they are in between closings on their primary residence/commercial and prefer to rent in the interim than lodge/purchase in a hotel/storage.What is an issue is where they conduct business as such.

Conducting business without a license can keep you from getting a license or cause you to lose any other license held.

Tortuous conduct, study that. :)

In PA, the quoted excerpt would be wrong and bad advice to follow, since the tax sale is conducted "subject to existing liens of record" - so the mortgage would remain in place, and the buyer at PA Tax Claim Bureau sale would end up having to pay to get clear title. 

(I also go down to Palm Beach County because I routinely conduct certain other business in Delray Beach, and Boca Raton).  

An LLC does not protect you, as manager, from criminal conduct.

My only caveat that I'd like to share per my broker is that listing agents tend to underestimate operating expenses so if you're planning to conduct a transaction without buyer representation, make sure you know how to properly analyze the property on your own.
