Rental application for existing tenants

[Anthony McKeen]

Fellow BP'ers,

We recently purchased a tenant occupied duplex around 1 month ago.  The existing tenants are long term (5 & 13 yrs).  They seem to be good tenants and don't want to move.  I'm providing new leases and applications as well.  Considering that they are existing long term tenants, do I need to ask for all of the typical info on a rental application?  i.e. bank info, employer info?  It seems that this info is only pertinent to rule out a potential tenant.  I'm still going to have them fill out the remainder of the application just so I have all of their info, licenses and such on file.  Any advice is appreciated!!!

Thanks!
