Duplex landlords: Charging diff. rates for similar properties

[Mauricio Quintana]

Duplex landlords,

I'm in a situation where I bought a duplex and one side has been rehabbed.  This is a class C property and the interest has been great on the rehabbed side.  However, I am realizing I may have over rehabbed for the area.  I'd like to scale down the rehab for the second unit and charge roughly $90 less in rent.  The totals would be $650 currently rehabbed side and $560 for the other that still needs work.  

My specific question for your duplex+ landlords is have you come across any instances where you have a 2 different charges for rents for leases signed at relatively the same time?  Issues meaning have you had to deal with one tenant complaining and causing issues that their rent is $90 higher? How have you dealt with this?
