*It is against board rules, and state and provincial real estate advertising rules, to try to modify the data (such as photos, the listing agent remarks, and listing details) for general IDX listings (where you or your brokerage don't represent the seller).
*If you wish to highlight listings represented by other brokerages, you can post thumbnail links and comments (such as on a blog page) about those IDX listings, as long as you (1) link to the detailed IDX page that includes the name of the seller's representative and (2) don't change any listing details on the IDX listing.
