if its a brand new starter site you can expect to sell for $60 - $120
this could be something you made this morning and listed in the afternoon - autoblog, seo service site, auto News,
no traffic, no income and what your selling is essentially the dream of a website in a box thats ready to go all they have to do is advertise.
once you sell a certain blog. create the exact same again with new logo and domain and sell again.
if you see a site like this for sale and look back through the sellers previous listings you will see loads of sold listings for essentially the same site.
ive even done this myself. if you sell around the $100-120 mark after the flippa listing and selling fees and domain cost you can make around $60 per site. make 4 of them a day. you build a catalogue of sites for sale and could get to the point where even if you sell 2 a day your profiting $120 per day.
it does get to a point tho where you just turn in to a website creating machine and it sucks the life out of you.
the biggest thing with peoples expectations is the dream your selling, add loads of BIN (buy it now) bonuses to make sure you get $120. loads of ebooks or articles you can buy off seo clerks, fiverr etc and give away with each site.
Ive even offered 12months free hosting on my server and send their own cpanel login details (i have reseller account with hostgator) - this saves you the work of moving it their hosting and they think they are getting another freebie (your also potentially storing up add on sales 12 months down the line when the hosting needs renewing
