Discounted Lease for Plumbing issue?

[Sam Marriott]

Hey Guys,

We have a plumbing issue in one side of a Duplex that we are currently trying to get a tenant in to.  The volume of water coming into the unit is not sufficient and when you run multiple fixtures the pressure drops off significantly.  We are still trying to pin point the core issue and plan to solve the problem, but it probrably will not be resolved before we get a tenant in.

The situation is live-able, but certainly not ideal.  So my question is...

Would it be a good idea to sign a lease addendum with a tenant to say that the lease is discounted by lets say $50 a month until the issue is fixed?  I see it as a good way to let the tenant know that we are serious about the problem, and let them get a discount for dealing with the issue.

Thank you for any and all feedback!
