Tenant request to split cost of an 'upgrade'

[Dan B.]

I've hot an interesting proposal from a new tenant. They asked me about splitting the cost of installing gas logs in the fireplace. Total cost $1200. They would pay 600, if they ever leave, they would leave it. Propane tank will be on the outside and professionally installed by watsons.

I'm looking for some opinions on whether this a good idea or not. Anyone have any thoughts? Would gas logs increase the value of the property? Would it present undue risk with a negligible value add?
