I would advise making sure that you communicate well with the other owners so they know what is going on or at least demonstrably could have known if they had paid attention. It would only take one noisy person to accuse you of poor behaviour and you might find yourself wanting some allies who know you have been doing good things responsibly altruistically etc.
You might want to think about succession planning too for when you get tired of doing it all. Perhaps a new owner can be recruited to the committee and trained up.
