Generates around $8k per year in Adsense and slowly rising. Plenty of potential to actually do something with it.
I wouldn't even think of selling it for less than $60k as it's an asset returning 13% on that amount.
People will say, "Yeah, but that's a ridiculous amount to ask." I agree, but where am I going to invest the proceeds that will return me that amount. This is a site that's consistently increased revenue for the past 7 years with close to zero hours of work.
If you offered me $40k tomorrow I'd say no. Because I'll make that in four years, and still have more to go.
