As a home seller, there are certain things you want to avoid telling your listing agent, including the following: You won't sell to a certain type of buyer: Sellers are federally prohibited from discriminating against prospective buyers based on race, sex, religion, and other protected classes. You won't disclose your home's issues: If you know of an issue or defect that could negatively impact your home's value, state law probably requires you to disclose it – so it's best to avoid hiding any known defects from your agent. You want to list at a sky-high price: Listing at too high of a price puts your home at risk of sitting on the market longer (or not selling at all). Agents may still want to win your listing, but may focus their efforts on other clients with better near-term prospects, which could hurt your listing. You're getting advice from another agent: It's best not to go behind your agent's back if you've agreed to work with them. If you're unhappy with their service, you can ask to work with another agent from their brokerage, or cancel your listing (then hire another agent).
