Security system in a Class A rental

[Stephen Bruce]

Good morning, BPers!

A tenant is moving out and has offered to leave his factory reset SimpliSafe security system in place for $80 (retail $250). I am leaning towards paying the asking price and offering it to my next tenants. What am I missing here? Am I unknowingly taking on extra liability by providing a security system? Can I have them sign a disclosure relieving me of maintenance and liability of the system? Keep in mind it is a class A rental.

I greatly appreciate the advice in advance!
