@Gary776 as @Paul1255 says, it's against Airbnb's terms of service to transfer an account (listing admin) from one person to another, regardless of what channel management software, if any, has been used. Airbnb requires reviews etc. to remain associated with the host at the time the reviews were left, not the property. I have heard that sometimes big property management outfits get special exceptions, but in general that is the rule.
