As long as you have incoming links to your site, you state in the sales pitch that the domain is for sale with traffic stats!
Incoming Links and Stats is all you need to use for the purpose of selling a site with affliate accounts. The rest is up to the new owner to update the links with their own code, and a letter to your present customers if any! that ownership of site has been changed.
90% of the time, a new owner will change the look of the site!!! and take advantage of incoming links that genrate traffic.
