While the vast majority of homes available for sale are included on the MLS, there are definitely exceptions. Firstly, strictly FSBO homes won’t be found on the MLS database. Likewise, off-market listings, also known as quiet or pocket listings, which are homes that are not marketed in the typical ways, will not be included on the MLS since the seller keeps the property quietly “in their pocket”, hence the name. It’s when sellers desire to test the waters, maintain privacy, or create a sense of exclusivity that could drive up a home’s selling price.
