When first starting out, try posting link exchange requests in various webmaster forums. For example, we offer a "Traffic Exchange" forum and so do other forums such as www.webhostingtalk.com - also, check out the threads that are already there - it's a great way to make contacts in your industry.

Something else to do is directly below your listing of partners, add a link called "List Your Site Here for Free" or something of that nature - and link it to a page on your site saying that you offer free link swaps.

Believe me, word does get around. Especially on a niche site such as real estate, the webmasters of all the popular real estate forums eventually get to know (or at least know of) each other. By swapping links with a few of these sites, others will start to see "this site is popping up all over the place" and check you out too.

I'm not a fan of linksmanager.com software. But what I do likeir sister site, linkpartners.com - it lets you do a search of various websites that all have link pages just like you, and are willing to do link trades with other sites.

In fact, there is an entire category of real estate websites that are also looking for link partners: http://linkpartners.com/lparts96.html
