The belief that “love letter” violations are a widespread problem has prompted the Oregon legislature to pass a law preventing a buyer’s agents from providing the seller’s agent with one. To ensure a seller won‘t select a buyer based on prohibited criteria under the Fair Housing Act, the law says that “a seller’s agent shall reject any communication other than customary documents in a real estate transaction, including photographs, provided by a buyer.” I’ve seen examples of love letters that appear to me to be totally innocuous that have been said to problematical. So my advice is to follow the Oregon mandate and avoid love letter liability.
