Let's face it: When your house goes on the market, you're not only opening the door to prospective buyers, but also sometimes to unknown vendors and naïve or unqualified buyers. As with any business transaction, there is an expected protocol to how sellers, buyers and their respective sales representatives interact. Should you find yourself in a sticky situation, alert your sales representative so he or she can address and remedy the problem.

The aggressive sales representative
When your sales representative puts your house on the market, typically all promotional materials state clearly that your sales representative is the primary contact for buyers and buyers' sales representatives. However, sometimes a buyer's agent will contact a seller directly to try to either win over their business or cut the seller's agent out of the deal. This is not reputable behavior and you should report it to your sales representative immediately if it happens to you.

The naïve buyer
Yard signs, Internet listings and other advertisements can generate a lot of buzz for your home. Some prospective buyers - particularly first-timers - will be so buzzed to see your home that they'll simply drop by. If this happens, no matter how nice these unexpected visitors are, it's best not to humor their enthusiasm by discussing your home or giving an impromptu tour. Instead, politely let them know that your real estate agent is in charge of scheduling tours and provide them with the sales representative's contact information. If you attempt to handle these surprise visits on your own, you might inadvertently disclose information that could hurt you during negotiations down the road.
