You say, “Selling them at these prices is akin to selling a shirt at Nordstrom’s today that you know will be on-sale next week for half-off,” and then imply that it should therefore cause problems for their conscience.
It seems to me that the mistake being made here is the implication that the realtor (or anyone else for that matter) knows what’s going to happen to prices. Nobody knows. Plenty of serious, unbiased economists don’t foresee a serious drop in prices. If a person spends all day on websites devoted to a perceived looming correction, and hears opinions which mostly conform to that idea, then that person isn’t really getting the whole picture. You can find reasonable opinions for both a rise and a fall in the future price of any investment, from oil to gold to stocks to shirts at Nordstrom’s. Are sellers of these investments also lacking ethics?
To imply that every realtor should “know” that prices will go down significantly and that therefore they are morally lacking if they sell real estate is very unfair.
