I have been doing a lot of website selling that past 6 months and have noticed many people struggle selling their site for a good profit on flippa and other sites.
I never use flippa, but I always go to private buyers such as private investors that I contact off line because they are looking for set it and forget it investments. As long as the site can help give them a 30% ROI, they are more than happy to purchase it.
I have always seen my site sell for 35%-40% higher selling to these type of buyers. Hope this helps you warriors, and happy selling.
