domain BuySellorRent.net Appraisals Please!

[CMarketing]

I have the domain names BuySellorRent.net, BuySaleorRent.com, BuySaleorRent.net. I am interested in getting someone elses opinion about what they maybe worth. Me personally I think there are a great name for a real estate web site! But, it doesn't really matter what I think...so help me out? How much are they worth?

I know BuySellorRent.com is for sale at about $40,000!

Thanks a lot!
