I do appreciate generating attention to the post for guys that might have some advice that isn't the obvious.

Im here looking for info or help on where or how to start on something a old high school friend is doing and it caught my attention.

Give them enough pressure, heat, or attention and the charming melts right off and your left with the rotten core.

Most are folks that have the emotional control of a 5 year old, controlling attitude, an omniscient narrative in every thread & topic, act like an online hall monitor, and constant attention seeking. 

@Shawn SheedyNice work on bringing attention to your cause via the article.

Here is what I would do:I would still close on the property but send a letter to the sellers broker and the seller along the lines of below (note I would have an attorney write it and send it):It has been brought to our attention there was a $15,000 insurance claim on the property.

I really admire that you've focused on such a unique niche that doesn't get much attention.

However when done correctly you shouldn’t need to write a single message to the majority of guests and still have them feel warm and fuzzy because you have been an attentive host.

Aren't you glad that some antisocial media influencer brought this "tax strategy" to your attention?

It grabs attention, gives potential guests an immediate sense of what sets your property apart, and helps them imagine staying there.
