Property showings happen whether MLS is involved or not. And it’s important to understand that Realtors® don’t just only show properties that are listed or associated with their own real estate company. Realtors® show homes that fit their potential prospect’s wishlist. The MLS is used for Realtors® to find, show, and close on properties – and whether a property is listed by a traditional real estate company or by an FSBO, FRBO homeowner, rest assured that it will be shown (should it be something potential prospects want, of course). So, no worries on that.
