I found these in 2 minutes… there are many, many more available. Hit up Yahoo, MSN & Google & just do a search for real estate article directory (no quotes) & dig deep – I’m sure there’s probably more than 100 you can find.

Now, I don’t think all of these directories will give you a great value – but I personally believe that topical relevancy is more important than page rank, but you have to be sure that the place you’re getting links from has a little bit of clout with search engines, too, or your link won’t really count.

Something you might want to consider, though – seeking out prominent real estate websites & asking them if they’ll publish a unique article on their website in exchange for the link(s) in the author bio. This would have to be a great article & it would have to be unique – but I use this method personally & it does work to get highly-targeted backlinks from authority sites simply for the asking. It’s hit & miss with responses to my emails… but it’s a viable option & alternative method of link building through article marketing.
