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.  

I started my Journey at the age of 18 in Rocky Mount, NC.

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.

Hey @Nathan Mount, @kayla d is going through this right now.

A roof is significantly higher up than a ground mount and should avoid enough dust. 

2) Based on the layout of the living room, I planned on mounting the tv above the fireplace.

Ikea uses a rail mount which hangs the boxes from the wall.
