There would be or can be if I advise on an individual basis in a specific note, I'm not willing to take $500 on payments or charge a % of some profit and take on that liability, that won't even cover my insurance premium.

this is a specific need you have and maybe there are attorneys here on BP in NY that can help, but having worked with jurisdictions before - with it being early december - these officials do not move very quickly so hopes of closing before year end could be complicated.

Not every lot will allow you to STR even though sevier county and the city propers do have specific zoning that allows it so you don't have to worry about them ever rescinding that right. 

Rent control laws are market specific.

Could any of you please advise us (not legal I understand) if setting up an LLC or these homes in a trust, etc would be beneficial?

I would also ask about your area specifically about how it is covered.

He had specifically said he’s okay with the north fencing and knows its to keep the homeless campers out, and who the police are very slow to remove.

No, more specifically deals found through networking with local real estate professionals, finding pocket listings, direct mail, etc.

If anyone has good attorney contacts in TX please advise and forward, thank you! 

Raising rent by a specific percentage isn't a very accurate way of handling this.
