Is it normal to have an opt out clause in a lease agreement? My current tennent would like to renew his lease but would like to add a 60 day opt out clause into the agreement. Just curious if this is a normal arrangement and if there would be any problems with this type of language in the actual agreement

It may not be standard but I see nothing abnormal about it, as long as you don't mind. I might want to write it such that certain months of the year that are hard to find tenants for need 90 days notice.
