I would like to point out that there are many fee-for-service real estate brokerages these days. They tend to charge lower rates in total, since their pay is not contingent on the sale closing, so home buyers and sellers can save money.
With that business model, you tend to get more consistent levels of service, and real estate brokers and agents can lead more normal lives.
Perhaps it’s time to be open to having some Shadchans change their business models.
