The big unknown is how inevitably rising interest rates and inflation will influence the markets.

Fear of the unknown seems to be what you're currently dealing with. 

There is no self-doubt, just the fear of the unknown as it relates to tackling something new such as this.  

That is an unknown.

There are numerous other items you could discuss (at least I would) but since its unknown what you already intend to ask I'll leave you with the two "legal" questions mentioned.

This is not the type of project you should do with unknown contractors.

I, personally, can't stomach being deceitful especially with so much gray area and unknowns, but some information is not their business.

I have no other better example than the link that I just posted above with the fairy-tale from the unknown attorney.

Sorry its me again...Actually I have been thinking about this a lot since I read the original post this morning so coming from a newbies perspective let me just say that when you arrive on BP & see that there are people doing what u want to do in REI & u want to learn the ropes, there is a lot of background stuff on the individual newbie that is unknown & we read posts or hear podcast etc that u can do this & u can do that & u need to educate then put action to it....this cud be bad advice for some newbies like Scott said with a bad financial IQ...BUT also that person may think if they don't act they will loose momentum or miss their opportunity or fizzle out, being afraid of that they act...wanting to be an Investor so bad they jump ahead of themselves...

At the moment it's unknown how they're going to monitor it and if what they do will actually prevent people from running Airbnbs.
