Here's the scope of my build. My client manages 7 mobile home parks and wants to display home listings on each domain (site). A parent company manages all seven parks so, ideally, I would like to build the parametric search using custom posts types/vies (wp-type) of all home listings in the parent company, then have that data accessible to all the park domains (sites).
1. Logically, if I could just maintain one database with updates, that would feed all the seven park sites. Possible?
