Just went through the leasing term wrap-up myself. The leasing company usually handles releasing your spare key and returning the registration. Quick heads up, might wanna check if there are any wear-and-tear charges, just to be on the safe side. As for the "Absolute owner" thing, you're good as is. No need to stress about that, it's just a standard phrasing on the docs. Oh, and speaking of stress, I recently bought my first home and got fantastic Mortgage Advice Essex from this Mortgage Broker. Super helpful, made the process a breeze. Highly recommend reaching out if you're ever in that boat.
