When it came time to upgrade a site that is using this component, I was a bit worried, because we had done a lot of modifications to the code. We were using EZRealty 5.x on Joomla 1.5.x. Taking this site to the latest version of EZRealty and Joomla 2.5 was made easy by the EXCELLENT SUPPORT. Kathy was more than helpful with detailed questions about the code and locations of the files I needed to modify. I recommend this extension highly.
