I’m not sure my place is for sure legally able to be rented out to 2 adults and 5kids!

Tell them they are adults and need to start behaving like it (worded more diplomatically). 

If you decide to entertain this, due diligence will involve digging deep into the business financials to understand cashflow, solvency, and liquidity, his personal finances, and searching for any liens or UCCs in place. 

It's entertaining, but in the doldrums of winter it gets redundant.

Minor or adult?

I'm starting to find this thread entertaining with the arguments that a Listing Broker vetting an unrepped buyer is seen as establishing an Agency Relationship.I like to do something called "Thought Experiments" which can at least help me to understand scenarios that are similar and may help work out the complexity.Scenario #1 - FSBO vets BuyersIf a FSBO vets Buyers, does this establishes a implied Agency relationship?!

Let's not go into how gross the hot tub was for just a few days (but we all know that's par for the course with a large group of adults & kids) and yes, I factor the extra for drain & fill although in this case, it needed even more cleaning.What I'm struggling with is what is the most professional way to reach out to the guest and to write my review?

You'll be entertained and you will learn a ton.
