The issue here is the pricing is consistent, while each transaction is different. You wanted high-touch service in a fast-moving market, great. But another buyer who does not want or need that service still has to pay for it.

An approach used by other service providers is hourly billing. Realtors could even offer distinct service packages like accountants ($XXXX to prepare taxes). A reason they don't is because the line items or hourly rates would be absurdly high to generate the same level of fees they get today.
