install decent exhaust/air moving devices. 

I would hold off on assuming you have a bigger problem until checking the box personally, and I would get a “tic tester” ($19.99 device that looks like a pen and tests for electrical current) and check your outlets and heater for power if that doesn’t work. 

Only 1 gas device in the building besides water heaters.assessed for 300.

There was a small disclosure of an issue in the sales contract, but I will admit to glossing over it in signing the electronic papers (the electronic form of signing itself through its extreme convenience can make this easy to do ... so don't!).   

Your tenants can pay the rent electronically (via Zelle, for example).

I recommend to scan invoices and receipts, and store them electronically. 

Like recurring electronic bill pay, but directly to another person, fee-free?

On the dog situation I have no rights unfortunately since it’s an ADA animal and it’s seen as a medical device.

I suggest owners insist on tenants using surge protectors plugged in to protect their appliances and devices as well as the property in case this ever happens. 

- Making sure that the lease contract of your PM does not allow electronic payment like ( creditcard ) or personal checks.
