If your broker is only allowed to work as a Seller's Agent, it is still perfectly legitimate for that broker to work with the buyer and treat that buyer as a Customer. If the buyer agreed to be treated as a Customer, there is no problem here. Being a Customer means that there is no agency or transaction-brokerage relationship and the buyer is simply a party with whom the broker is working by communicating, showing, and possibly writing an offer. There is no standard language in the Colorado contract saying that a Seller's Agent can't work with a buyer and treat him/her as a Customer. The only thing that would prevent that would be if you had a clause in Additional Provisions stating that your agent could not work with or even communicate with a buyer in any capacity. Getting information about the property itself and passing that info to others is always legitimate regardless of the status of the broker. As your agent, the broker can't give information about you (the client) or your motivation, willingness to negotiate terms, etc. but can certainly gather and disburse facts about the property itself. As a matter of fact, HOA information and things like that should have been requested or researched by the broker at the time of listing. It sounds like your agent is simply trying to sell your house to somebody, which is what he/she was hired to do.
