I'm here to build long lasting relationships so I can work with fellow investors when I permanently move back to GA.

In 2012 I relocated to maryland permanently  and began looking for work. i came across a home that was being renovated and made contact with the person in charge and was hired to work.

If it is a permanent closure  I would close it off at the house straight between the walls, I don't like that though from a function standpoint.

It has 2 major and practically permanent advantages: Weather(especially relevant in the climate change era) and location between Berkeley and Stanford, that no other place in the US can successfully overcome.https://www.biggerpockets.com/forums/888/topics/850101-bay-area-housing-2020-crash-or-no-crash

Sounds like a more permanent solution.  

This is causing permanent damage the flooring and subflooring, which you are responsible for, but can be a health issue for other residents in the building as well.Effective immediately, your apartment must be thoroughly cleaned and sanitized and maintained.

Nobody else is the wiser.But, I can provide a letter from Social Security, too, that states I am permanently disabled.  

In our lease it states that the tenant must ask permission before making permanent modifications to the property, it also states that any tenant upgrades shall become the property of the landlord when completed and paid for by the tenant, and shall remain on and in the apartment on the expiration of this Lease.I am curious to hear what others do, when a tenant wants to make an upgrade that is an improvement to the property?

I've read they've even gone so far as to claim that if you keep a storage locker in the state that they consider that evidence that your move was not permanent and you intended to return to the state.  

I agree that permanent flooring in rentals is an issue in big traffic areas.
