Hi

I just joined this great forum. Hoping I can get some guidance to the right path. I am quite new to domaining and have collected around 212 domains in various niches. Some I have developed into sites. Through my research of niches search volume and cpc I know my domains are of value. Some of my domains are already making income just parked on google.
I am looking to sell many of these domains now.

I am wondering if it is possible to appraise the following I have on laptops.

Any advice on how to market and approach potential buyers?

I have Listed many on sedo in the adult/ dating niche for last couple of months and ordered category listing for some of these. Had some interest also but I think takes a long time on there.
