Problem tenants (and placating your good tenants)

[Chris Bruni]

Been in the rental business for nearly 20 years.  Had great experiences and the occasional bad tenant over that time.  Right now my issue is in an older tri-plex in a smaller community (25,000 population). Unfortunately, I picked a bad tenant late last year that is affecting the two other good tenants in my building.  I am in the early stages of the eviction process (yes, less than 3 months in) and my good tenants are aware of this.  Additionally, the bad tenant was only given a short 5-month lease to start (as I knew her rental history wasn't strong) so the clock is ticking. 

My question for the community is what have you done for good tenants to encourage them to stick it out while I'm getting rid of the problem tenant?

Thanks in advance!
