I agree with PD. If you have two identical house, one list range @ 500-550k, which the other list @ 530k and both sell for $520k, then this disprove that people who don’t use value range left money on the table. Only way you can prove that the one not using value range left money on the table is to find two nearly identical house and have one w/ value range selling for more than one w/out. Other than that, these statistic doesn’t mean much.
