It turns out that the Real Estate module comes with self defined configurations and own database, which means that the sample comes with an already configured SitefinityWebApp project and the modules are configured in a certain Sitefinity version. The one in our github SDK is for 6.3 version, which means that it uses a database upgraded to this version, as well. If you want to configure it on different versions and project, you should install the modules separately and at your own. We support only the full example, since it is made only as a sample and a guide for what could be achieved with Sitefinity, as well as, a roadmap for this functionality.
In order to configure an earlier version of this sample and use it for a certain version, you should install this particular starter kit from the specific SDK version - in your case Sitefinity SDK 6.2. You can get the particular version of the SDK from your account manager or writing directly to firstname.lastname@example.org . They will be more than happy to provide you with it and more information about Sitefinity and the SDK itself.
Keep in mind that most of the samples are independent and will not need this configuration in order to work on various Sitefinity versions.
I hope you find this useful.
