I would say it depends on how willing you are to market the name and the sc extension to end-users. Marketed as Real-estate.sc where .sc=South Carolina or Source, you might find an end-user interested in the name. Granted, the hyphen doesn't help and it may be a good idea to avoid hyphens in general for ccTLDs, but there is at least a glimmer of hope with this name, IMHO. Enough hope to compensate for the high renewal fees? I leave that to you.
