WP Property Listings is a Very Simple and Easy to use Plugin. All this Plugin does is that, it creates 4 fields in your WordPress Posts Editor. These 4 Fields are:
Bedrooms 
Bathrooms 
Rent/Sale 
Cost 
And just with the convenience of these options, a regular post is converted into a property listing. Currently, only works with supported themes. Support for all themes will be added in future.
If you are a developer and have integrated this plugin with your theme, contact me.
