was thinking of letting them know I leg rent more than a certain amount here in California unless that person decided to move out and one of their other not on the contract tenants signed a new lease at the higher rate?  

You may or may not have a personal guarantee, but probably will.  

You can always pick those up after the lease ends via a judgement in court - you will have the same odds of collecting unpaid rent (close to 0).Sometimes we take it personally when folks do stuff like pay late every month - landlords live longer when we learn to not take things personally.

Personally I’d have them start saving up and get traditional financing and pay you off.

The doctor found out that I was going to visit those 10 to speak in person with the borrowers and try to decide on the best course of action.  

As I've been learning, there are the key taxes to understand when investing into a new area or state:- State business income tax (if you have an LLC)- State personal income tax (if they want to tax you too, even as an out-of-state investor)- City personal or business income taxes- Any registration fees due the city/state- City/state property taxesAnd I'm sure more!

Put an enclosure around it, heat it when necessary and  call it an indoor pool.My next personal house is just going to have a smaller pool like one of these.

STRs that I could use for personal use (family vacations) once or twice a year.  

That person already had that money spent in their head even before the property is sold

Personally if it is a loser for 2 years, then it is a bad deal.
