I'd have new leases prepared and any addendum's for crime free/ drug free. pets, whatever ready for them when you sign a new updated term with the rents increased..Study the landlord tenant laws for your state and comply with notices and you'll have a good start.

Mission successful.Prior to reading all the posts I decided to send a "Late Rent - Reminder" and a "Unauthorized Pet Lease Violation" notice to the Tenants.  

What they're doing is taking the entire amount (taxes, cleaning, pet fee, etc.) and claiming the 4% to 9%, which is a joke. 

Look on Craigslist for properties that are nearby and have the same bedroom and bathroom count, garage/storage options, and matches utility treatment and pet policy that you intend to use.  

NO Way,, it's for the duration of the period they stay with in the same apartment..If it a pet deposit fee. 

maybe add an addendum for a damage and pet deposit(?)

The common thread of complains are: debris, too many people living in property, unauthorized pets and utility disputes on shared meters. 

And unless glade came out with cat piss scented plug ins, the tenants are not tidy with their pet.

We allow pets in ours and can charge a fee and higher rents because most of the competition does not.

Tenants seem amazed that I've done things like fix a loose baseboard, tighten the screws on a wall switch faceplate that was coming loose, removed and cleaned off an air return that was clogging with dust and pet hair and basically just take care of little things.
