This is a rather bizarre discussion. The whole point of VT requiring a quarantine is so that you don't infect other people you come into contact with in case you are sick. If you go only to your own private residence and nowhere else, there's really no point in forcing you to stay there for 14 days before subsequently leaving the state. It is quite different from someone going to VT only for a day trip to ski where they are obviously out in public.
VT does address this specific point in their FAQ:
So if someone goes to only their own residence to clean it out and does not come into contact with others, there's absolutely no requirement to stay "in quarantine" for 14 days before leaving VT. VT point blank says so.
VT does address this specific point in their FAQ:
If I am staying in Vermont for less than the minimum quarantine time, may I still come to Vermont?
Yes, but only if you are in full quarantine at the lodging establishment or private residence in which you are staying while in Vermont. Quarantine means you do not leave the room or house in which you are staying and make no trips to the grocery store, restaurants or any other places where you will come in contact with others. Using lodging property amenities such as pools, spas, gyms, recreation equipment or other general use facilities is also not permitted.
