I've put a lot of money into it over the years and I have a lot of great titles and extras, but I lack the desire to play anything anymore. I have 201 titles, some of which are F2P like TF2 (yet I have tons of items). Most of them I grabbed from sales for cheap, but I'd like to get at the very least 400 for the package. What do you think would be the best way to go about this? http://steamcommunity.com/id/sirjables
By deleting that post and quietly asking around your friends if anyone wants to buy it. Valve doesn't recognize transfers of account ownership, so if they see you transferring your account to another owner they could just disable it.
