Most of my best acquisitions actually came from contacts in the industry. Webmasters who had quality websites and wanted to sell them knew that I as buying websites and turned to me for a quick hustle free transaction. I get a good deal and they get to bypass the exhilarating, and rather frustrating process of selling a website.
The next best place for me was through webmaster forums, like DigitalPoint and dozens of others. As there are many buyers and sellers on those forums it’s frequently the easiest way to sell or buy a website, especially for smaller websites.
And, finally, flippa. As it’s a fairly big marketplace I frequently find good deals and quality websites to buy there. Sometimes you have to sort through the rubble to find the real gems.
