Interesting conversation today among Realtors as to Buyers' Agents not showing up with their clients for their scheduled showing appointments and not bothering to call to cancel. Any ideas would be welcome! Our sellers know that this is not their market, yet they are often very careful to leave the house in tip-top order, on schedule, and then to realize later that no one came by as scheduled, or called, can be very disheartening. It also is generally left to the listing agent to speak for that buyers' agent. Of course you have a lot of homes to try and fit in, but let's be considerate!
