This website states that if you have a tourism leaseback which you wish to sell then you should first contact your management company about resale. Some of the larger companies (like Pierre et Vacances and Odalys) have a resale department.
What is the advantage of this rather than an independant agent.
MGM asked me for 16% commission to resell my property, an independent agent is something like 5% so it appears the advantage is for them and not you.
