I'm a bonehead(?): I agreed to PM suggested large rent increase

[Marco G.]

I purchased a number of adjoining properties mid last year. This unit came tenant in place on their first year lease. My first lease renewal of 2016 comes up next month and PM suggested a 9+% rent increase. I was very apprehensive about such a large increase and discussed it with them and they didn't think it would be a problem, and if it was, they'd ask for a "counter offer" now that they knew I was willing to be flexible. All of this seemed contrary to how I would do it myself, but the increase would bring it up to par with new leases over the past few months AND I'm really trying hard to not be such a micro-manager. I also expressed my apprehension especially because the property will require a month of vacancy and a few months worth of rent in rehab/updating with what needs to be done. Oh yea, and the leasing fee. Tenant immediately put in their notice to vacate. Tenant always paid on time and never made any frivolous service calls. I let them talk me into it against my gut feeling and feel like an idiot. I'm sure I'm not the first, has anyone had experience salvaging the tenant relationship in this instance? I feel like I can't really go back and say "just kidding, no increase for you"...
