What did she request? Usually when a long-term tenant leaves a dwelling the landlord does the carpets, painting, etc. It's part of the cost of being the landlord. Maybe you need to come up with a counter offer to her request. (A shot in the dark since you didn't tell us what her request was. But it's a shame to see a big crimp in your plans.)

My dog-corral arrived yesterday, so one day soon I will move furniture out of the front room and shampoo that carpet, then block it off completely to all of the dogs. Then I'll set up the corral, and fill it with dog bedding. The younger dogs will be able to get in and out (the height is 32"), but the oldest won't, and she's the one I want overnight on tile on washable dog bedding with access to the dog door into the yard. I still have to decide what to do with the carpet under the dining table. Shampoo it once more just for the heck of it, and see what evolves.

My ex told me about an Iraqi guy he visits every so often who specializes in cleaning Persian carpets. It occurs to me that this old dog sometimes comes into my room during thunderstorms and may have dribbled on that carpet. Time to take it over for the first cleaning it has probably had in 100 years.
