One that I'm getting close (hopefully) to the end of, was a flip that was a public nuisance property with two lots on either side full of junk (like 10 dumpsters worth..)There was great opportunity with the house, but we bought the other lots as well and cleaned them up (as no one would ever buy the house with those lots filled with junk).

For a good tenant that has paid on time and was keeping the place in good clean condition I probably would have just eaten the charge.

I did a check on a guy 10 years ago came up clean as a whistle on my landlord association screening service.

The guests have a credit card on file and your policy should allow you to charge for damages or excessive cleaning.

It's a lease, not one of those clean energy assessment lien crap things.

Leases are signed electronically (esign.com), and I set them up with RentRedi for deposit, cleaning fee, and rent payments.

Then when the tenants moves out, you can assess if there's any damages or cleaning.

Put language in your lease about use of the screen for all fires.I always made it the tenant's responsibility to have the chimney cleaned at least once per year for the built in fireplaces and twice per year for the store bought types as they have smaller chimney piping.  

Definitely helpful.I got a lawyer who did overcharge me a bit but the tenant left the property spot clean.
