I found these great articles on how real estate agents or brokers should blog, and they should not blog about their listings. I know that agents, etc. think that they have to write about their listings, but you shouldn’t. You really shouldn’t.

Topics that you can write about are the neighborhoods, schools, local activities, buildings, permitting and information that will be useful for someone considering purchasing or just learning more about the area. Become an authority.
