You'll no doubt encounter nosy neighbors, too. They live nearby and just want to satisfy their curiosity about your home - or even about you.
3. Agents scoping out the place for clients
Agents constantly check out properties for their buyer clients. The vast majority of the time, they're professional and courteous. There are exceptions, of course. Not long ago, in the living room of a packed Sunday open house, an agent sat on the couch and spoke to her client on the phone. The agent summarized the property loudly and in none-too-complimentary terms.
"The finishes are cheap, the floor plan is off, and the bathrooms need updating. Don't waste your time coming over here," she said. Needless to say, the seller's listing agent - who witnessed the conversation - was flabbergasted. Even some of the buyers touring the property felt uncomfortable. The listing agent politely asked the other agent to continue her conversation outside.
4. The agent who lost the listing
In many cases, a seller interviewed multiple agents before selecting their listing agent. Sometimes agents spend a lot of time, and even some money, working with a potential seller to secure a listing. Obviously, not every agent interviewed will get the listing.
When the property lands on the open house circuit, an agent who lost the listing may visit. They want to know if the seller took any of their suggestions. Did the seller paint the orange room a more neutral color or renovate the kitchen or bathrooms as suggested? The open house is sometimes the losing agent's chance to run through the property anonymously, as most agents usually won't know with whom they competed for the listing.
5. A previous owner, or one of their relatives
Over years of open houses, a busy listing agent will surely run into an old seller, or their children or grand kids who grew up in the home. These people come to the open house to see how it looks and to reminisce. Lots of memories happen in a home, and the opportunity to go back in time can be a real treat.
