I lived in rentals in Manhattan for many years, and you can leave the walls full of anchor holes and tv mount holes and the such, and they never deducted from deposit.

I’ve been debating between putting in new furnaces, running baseboard heating, or installing wall mounted heating and cooling units.   

Most are simple things like the banister mount broke or some floor trim came loose, that sort of thing.

.- Depending on the motorized opener being wall mounted or ceiling mounted you will need to make sure you have proper clearances for the tracks and head space for the roll up.

I would coin this chapter "Zeus's Decision" because we will experience massive differences all decided upon what comes down from "Mount Olympus" and the "God's Of $". 

So then I started to do research and realized that a wireless speaker is a good option but it's better to put a speaker, like Sonos, mounted on the wall and put some Echo dots (the ones that comes with a clock) around the house.I am afraid that using the echo dots option would bring the guests to steal the dots...

We left a bookcase over there( we first asked if she is okay with that as it was attached to the wall) and she deattached it and mount big screen TV over there without asking us first as lease says if tenant is going to do some modification, he/she asked to landlord first but she never asked.Please guide me what should i do as lease is year long and i dont know how much will she damage my house .

L&E Properties based in Mount Holly manages all our property in the area.

Don't be afraid to take a tenant to court when you're in the right, and let expenses mount and mount as you try to figure out what to do.That the best defense is being "a good landlord" has been said a lot, but it says a lot, too.
