If you are looking to just not renew the resident then a "notice of non renewal" would be what you provide and no signature is required. 

Lease is up 10/31 however they are local business people and have no desire to move, just continue renewing the lease. 

Thank you all.I had created a ticket and indicated that he will need to report all issues right away.He has gotten very comfortable to wait until the end and then text me or call me with an urgency instead of creating tickets.That ruins my weekends needlessly and does not allow me to plan.This might be my fault, in part, because I allowed it to  go on and people/tenants start to take advantage of "courtesy" as business as usual.If this behavior does not improve, I may not renew the lease.There are other good tenants out there who will be happy to have an upscale unit like mine.

What if I renew the lease next year and the cosigner doesn't want to cosign any longer?  

Renew if you want.  

The platform would be used for monitoring and enforcement purposes.The motion also instructed the department to ensure within 90 days that the public be able to view whether any property in the city has a home-sharing license, a home-sharing license renewal or an extended home-sharinglicense."

During a tenant interview, you may discover that there are certain tenants who you expected to renew their leases, only to learn that they have decided not to renew because they have complained about HVAC issues to the current Landlord a dozen times only to have their complaints never addressed.

My understanding is that the amount you can raise rent per year is capped and there are automatic renewals for tenants.

This obviously leaves the risk with you that you may have to close if they do not vacate in time, but it's a hybrid solution that could work.The last option would be closing with the tenants in place, serving them an option to renew / notice of rent increase at the market rent you want, then proceeding from there.

Keep an eye on it and revise when renewing if it seems off.
