I am foreseeing a bit of a push back or even turned-off potentially decent tenants by the $50/pp screening fee, mostly for a family of 4 ($200 out of pocket).I was wondering if offering a credit of either 50% or the full 100% of the screening costs from the first or second month's rent is a good idea.Thought?
