UPDATE: We ended up closing around 8wks instead of their requested 2wk, due to one of the 2 owners/sellers' power of attorney papers being from while he was on vacation overseas.Only the front door keys were given, so we had to change the back door locks/keys.2 weeks after closing, various agent were still walking around and into the property's rear where we were gardening, and showing us on their phones that the property was still listed for sale and 'Active' on c21.com by Agent-owner's listing broker.Was wondering why they never updated it still yet - not pending, not in contract, not even sold after the sale til i complained to the broker people were walking in to inspect.Wonder if there are fines for not updating listing status, and who imposes them - MLS, CalBRE, or?
