51% of Parker homes are valued above similar homes nearby
We compared each of 1,949 single-family homes with its most similar neighbors (same neighborhood and quality, similar size and age). 51% have a house value above the median of those homes: together, $27.9 million of house value above them. Texas lets you protest a value that is above the median of comparable homes.
We rate 433 "Yes" and 1,127 "Maybe". If every one of them protested and got the reduction their comparables support, their owners could pay about $282,966 less in property tax a year.
