What price can I expect if I'll sell domains with traffic?

Hi.
I have 8 domains with traffic.
Niche: Adult
Content: none
Domains Age: 3-6 month
Traffic: 5000 uniques per day. 30% USA, 30% Europe, 30% Asia
Revenue: $800 per month in average from affiliate programs
What price can I expect, if I'll decide to sell them all? How you think?

 

I'm a little confused.
How can you have 5000 unique visits per day with no content on the domains? This kind of traffic would demand a considerable amount of content to be present on the site, unless the traffic is coming from click farms and there is absolutely no organic visitors.

Whoever looks into this should be asking how the hell you can claim to have 5000 visits per day, making $800 a month, with nothing at all on the domains to gain that kind of attention.

 

I'm assuming he wants to sell the site entirely.

 

Generally speaking and not examining the logical or the reliable part of your post, i would say x 12-48 months revenue

 

the question is another, why selling a website with a revenue of $800 per month?
