Domainah,
There are a lot of great local domain names as you point out. Many of them do not have the term "real estate" even in them.
Ex. CondosNearUM.com or HomesInArcher.com
These are worth $$ to Real Estate Agents with no web presence yet. Once they find out the name they want is gone and every one the think of is taken, they become an excellent market for the ones above. One sale makes the ones above seem like a bargain at $1500 - $2500.
