Yes there exists a WP plugin for Optima-CRM. You can freely download and use this plugin at which point you can configure the settings for layouts and behaviour from the many possible combinations. Furthermore if you are a WP developer, you could use it as a base to customaise the coding of the plugin to fully match your needs.

We would like to draw your attention though that WordPress is not the most ideal technology for real estate websites. The many templates that are provided for WP unfortunately do not cope with the mass data that is typically stored for properties and their images, which makes WP a slow environment for loading and navigating properties. It is possible yes, and we have helped several companies with their WP installation to use in conjunction with Optima-CRM, but need to point out that if you have the option to change the technology to a pure PHP/JavaScript framework, you and your visitors will greatly benefit. Ask us more details and we'd happily show you why!
