Oh, believe me, it DOES happen. If a realtor shows a home they have listed, and avoided showing houses listed by other realtors that may also fit the requirements, they are likely trying to keep the whole commision for themselves. So I believe the motivation is there. My question is, based on the code of ethics for the designation of "realtor", is that ethical?
In our area, one realtor, whose buyer wanted a second showing/utility costs (evidence of interest), called my realtor and chewed her out over the price, even though it was right-priced with the market (was lower in price several years ago). So not sure they were working together. If the buyer wants the house, it is priced right for the market (less however much they negotiate down), is it the realtors helping each other out when one realtor pulls a punk card, acts like a jerk, and blows the whole deal? The buyer loved the house.
