Lawyers are making quite a living, including buying national sports teams, by suing landlords of city properties.  

Attend library functions, Local high school sports games, always have business cards and know what is new on the market.

AND, we’ve now got 3 Major League sports teams with FC Cincy.... although some here refuse to acknowledge the Bengals as Major League. 

I know RUBS can be implemented in LA, but I'm not sure it can be executed on an existing lease.This may be overkill, but have you considered installing one of those smart-home devices that measures water flow through a pipe?

Parents come many weekends for sports events, etc.

They never had to ask for gas money, could use the card if they were going to dinner with friends (after asking for permission) or on sports trips, I got the points, and it slowly started to build their credit history. 

If you walked up to Michael Jordan and said, "I want to be learn sports" he would walk away.

If you are looking for the most flexibility, I would consider searching for homes with no HOA in these Scottsdale zip codes:85257, 85250, 85251All of these would be close to the action of Old Town Scottsdale, seasonal sporting events, ASU events, golf and hiking and all the things that draw people to Scottsdale.I highlight these 3 zip codes because HOAs are rare here and you will find remodeled or in-need-of-remodeling homes, depending on your strategy and budget.Most investors consider a swimming pool a must since people come here for the sun and fun.Check out Scottsdale listings on Airbnb to see which ones have the most bookings and charge the highest rates to see what's working best.

Lots of people visit for conventions, sports, music, and various get togethers (more so post covid but still maintained pretty solid presence during 2020 all things considered).

I guess it's more of an ethical problem than anything at that point... do you hide the issue and put a bandaid over it with a sealant or do you do what the EPA suggests and mitigate with a sub slab negative pressure device?
