Our theme database uses specific names for certain fields. Out of the box – you cannot make what you wish without importing properties and assigning them to the fields names we have.
The only way we know clients manage to import properties is with WP ALL IMPORT. We do not offer technical support for this plugin as it’s a third party – but from clients’ say they have good support and even paid developers to assist if needed.
You need an xml or cvs ot import with them.
And there is a forum where client share experience with this plugin here – http://wpestate.org/forums/topic/wp-all-import-google-maps/
We posted in there all we know as well.
