I feel like once the leak is found it would clearly be my duty to repair it (unless the tenant caused it somehow), but when it comes to a suspicion of a leak, what would you recommend?

The whole topic of tax can cause many to over complicate it. 

You know they didn’t cause the damage.

Side note, I'm also considering refinishing the vanity top cause the sink bowl has some scratches in it.

It seems like it is coming from a place of good intention, but is not particularly well thought out and opens the door for a lot of serious issues.I fully understand the therapeutic and healing benefits of pets for certain people, but there are already protections in place for service animals as well as emotional support animals that protect this subset of pet owners so I don't really understand why this bill is necessary - seems like it will cause far more harm than good, and again, this is coming from someone that likes pets! 

This led to us "talking shop" for hours on end (cause who doesn't love talking real estate?) 

If the buyer is going for a VA or FHA loan that is yet another thing that causes more headaches.

The property cash flows really well for us but it is frustrating that our tenant is causing increased wear and tear on the property and breaking all the rules we initially set in the lease.....   

The heater malfunctioned causing carbon monoxide exposure to guests enjoying the pool.

Numerous factors that cause speculation on appreciation to be a very risky game.
