For example, my ad will state whether we accept pets, that we want provide income around 3x the rent, and that every adult must pass a credit/criminal screening.

Worse case, someone gets hurt or killed and you could be held criminally liable as part of the conspiracy to commit the crime even though you didn't intend the result.  

I can feel that push internally, too—getting out there and connecting with people one-on-one is really my style.

If most everything is internal it usually doesn't make too much difference.

If you bank your timeshare (I use RCI) or there is  Interval International, two of the largest ones)  then you can reserve a timeshare at a more popular, in demand location.  

Criminals go where crime is easier and where they can avoid attention.

Over time, they raised prices, cut the lead amounts, and had their Internal telemarketing team make the first contact and then tried to "warm connect" us.

If you're in Frisco or any nearby Texas city, and are willing to accept an intern to mentor who'd be willing to show me the ropes, please do...At this point finding a mentor in the summer (anytime without school) would be my best card at the moment.

I started reading the IRC and realized it was not contrived by the same type of minds that write criminal laws immediately! 

Additionally, title companies and may have an internal real estate attorney to help with the contracts and sale.
