Co-mingling means that your search results pages contain listings from more than one MLS® System when you have more than one MLS® System on your IDX account.

As of 2016, many real estate boards and MLS® Systems permit co-mingling with IDX listings from another MLS® System. However, others do not.

If co-mingling with another MLS® System is not permitted by your board, and you have IDX from more than one MLS® System on your account, you can only use Advanced Search options (which separate listings by board), and you cannot use Basic Search options (which can co-mingle listings when there is more than one board on your account).

If all of the boards on your account allow co-mingling, you can use both Basic Search and Advanced Search options in your IDX.

Co-mingling rules generally are not applicable if you only have one board on your account.

Please note the following!

* In almost every MLS® System, non-IDX listings (such as FSBOs and pocket listings) cannot appear on the same search results pages as IDX listings.

* Any listings that don't come from the IDX data feed of any MLS® System must be displayed on separate search results pages.

* You must be a member of each MLS® System for which your website co-mingles IDX data (and you must be approved for iHomefinder IDX by each of those MLS® Systems).

These MLS® Systems Allow Co-Mingling with IDX Listings from Other MLS® Systems

*Please note these boards do not permit co-mingling with non-IDX or non-MLS® System listings (such as FSBOs or pocket listings).
