I sold 5 sites on Sitepoint (name before it changed to flippa) same format, essentially the same site.<p>I provided complete transparency, with regards to reports, traffic, what I used for Adwords campaigns, monthly revenues and exact expenses. I also provided information on how I built/got content for all the sites. I answered all questions as they came in and even created secondary admin accounts so users could see statistics etc. in real time. (only if they requested by DM)<p>My lowest selling site was $800 and my most was $18,500 the user that bought that site re-skinned it and flipped it 6 months later for $72k, with less traffic and sales then what I had .. clearly I didn't know what I was selling, these were "fun" projects for me, that I got bored quickly, i find the fun in coming up and executing and once it get's to maintenance, I find I lose some interested. There are perfectly legit sites out there, you just have to dig and do your research.<p>for buying, I bought 3 sites, 2 of which were under $500. one site I bought for $2k was a total scam! The user falsified all the data and I fell for it. I was able to get my money back through google payments though.<p>one of the users on here recommended using Escrow, I'd agree.<p>If your selling a legitimate site and can document all the elements of the business for users, you should be able to get good value for it. Just be careful! There are a lot of scammers on the site.
