For the most part its just health and safety items, which are items we should have remedied anyways.As someone else mentioned, biggest thing to avoid is having the house tagged as vacant which the city will do if it sits empty for too long (handful of months, grass not cut, etc).

On the one hand, I can see it as a positive indicator, for example of market health and increasing suburbanization. 

I moved in about the first of the year, but already the showerhead is showing signs of being plugged up on many of the ports and the shower/tub already needs a deep clean because of rust and hardwater buildup.

And in many cases this may be warranted as health and safety issues may be present.  

Last month Atrium Health purchased 40 acres a mile down the road. 

But I draw the line when there is risk of damage to the property, annoyance to the neighbors, health concerns, pests, etc.

You are disputing a condo agreement we do not have and we know nothing of your paint and vent beyond what you say.Regarding amending the lease, it can be a simple document you and your tenant sign stating that you are amending the term of the lease to be 2 years, and the tenant has an option to terminate the lease at 1 year.Regarding the bathroom, if it has a tub or shower and no other ventilation, I would go with the vent fan as the root cause.

Did you make sure their health provider met the requirements of AB468?  

Need Game room, hot tub, so on..

Cosmetic repairs that don’t pose health or safety concerns are typically optional.Then be very transparent and communicate thoroughly to the tenant, as to provide a professional explanation for your decision forward.
