If I discontinue REALTOR® membership or my membership lapses can I still keep (or register) .realestate domains?

Yes. Your account will be turned into a non-member account. The .realestate domains will remain yours and accessible in your account, and you may renew or purchase additional ones. If you have .realtor™ domains they will be suspended, and you may no longer be eligible for those domains until your membership is again in good standing.
