Betsy, you need to understand with short term rental, the review system only works if it is linked to the account holder. It is the host who accumulates the reviews, not the property, and a property's past history stays with the host, it is not transferable to someone who has no track record, no experience.
Everything that has been said about a property's past reservations would be completely useless as a guide to the future if the person who controlled those reservations was no longer on the scene. Everyone hosts in a different way, with a different style.
Reviews stay with the host who generated them.
Where attempting to transfer a property gets complicated, each listing is tied to the account holder, who is the 'listing admin' person, and you cannot transfer the listing admin person. As a new purchaser the listing admin could make you the primary host for that property, add your bank account info to the profile and let you manage that listing as if it were your own......but they would still own the reviews, you could claim them, but not in your own right, only in conjunction with the listing admin!
And not too many people want to continue a long term association with a property they have disposed of and no longer have any control over!
Betsy there is nothing stopping a property's existing host unlisting the property and another person relisting it as a new account holder......but the new account holder can't take the properties past with them, that always remains with the previous host!
Cheers........Rob
