Parker Realtor, without the guesswork.

Parker is a city of about 6,462 people (July 2025 Census estimate) in Collin County, bordered by Allen, Plano, Murphy, Wylie and Lucas, and best known as the home of Southfork Ranch, the setting for the TV series Dallas. Almost every home is owner occupied (98.9%), and the Census puts the median owner-occupied value at $859,600 and the median household income at $229,080 (ACS 2020-2024). Zillow's typical home value was about $1,089,000 in September 2026, down 1.4% from a year earlier.

For tax year 2025 a Parker home paid about 1.58% combined in Plano ISD (city 0.310439, Plano ISD 1.03955, Collin County plus Collin College 0.230563 per $100) and about 1.67% in Allen ISD. On a $1.5 million home that is roughly $23,700 a year ($1,976 a month) in Plano ISD or $25,000 a year ($2,084 a month) in Allen ISD, before the state's $140,000 school homestead exemption and the county and college exemptions. Parker offers a $50,000 over-65 exemption but no general city homestead exemption.

Get the district for the exact parcel and request the current tax bill, because Parker has no general city homestead exemption and part of the city is in Allen ISD rather than Plano ISD. If you want new construction, ask about the planned Southfork Ranch lots, but confirm council approval, utilities and timing with the city before you count on them.

The lesson in Parker is to read the tax bill before you read the brochure. Parker's city rate has held at 0.310439 per $100, but the city's own notice shows the average homestead's taxable value rose 7.45% to $1,043,302 for 2025, so the city portion of the bill rose even with a flat rate. Parker also offers no general city homestead exemption, so when you compare an estate here with one in a neighboring city, compare the full bill, not just the rate.

In Parker the median sale price changes by hundreds of thousands of dollars from one subdivision to the next, so price against closed sales in your own neighborhood and lot size, not a city average. Buyers at $1 million and up tour with inspectors who look hard at roofs, foundations, pool equipment and septic or drainage on large lots. I would rather spend a seller's money fixing those items before listing than give it back in a price cut later.
