I deeded back a 2 bedroom lockoff at Westin Desert Willow in 2019. I paid the fees at the beginning of the year, and then I contacted them, by phone, telling them I wanted to deed it back to them. At first they sent paperwork to fill out as if I wanted to sell it, but telling me they were not currently purchasing anything, but they would hang on to the paperwork in case that changed. I contacted them again, by email and said I just wanted to deed it back to them. It ended up being about a 4 or 5 month process before I received paperwork saying the deedback was complete. The only cost on my end was the cost of a notary when doing the paperwork, so it was a fairly easy and painless process.
