Good question! MLS stands for Multiple Listing Service and it’s basically the master list where all agents post new homes for sale. Third-party sites like Zillow pull from the MLS, but there’s sometimes a lag or missing info. If you want the most up-to-date details, it’s better to check straight from the source. I used when I was looking, since they have direct MLS listings—so you get real-time updates and sometimes even see houses before they show up anywhere else. It made the search way less frustrating for me.
