Wylie Realtor, at the right price.

Wylie is mostly in southeast Collin County, with smaller pieces in Dallas and Rockwall counties, between Lavon Lake and Lake Ray Hubbard on SH 78. The Census Bureau estimated 63,842 residents in July 2025, up from 57,526 in 2020; 77.4% of homes are owner occupied and the median household income is $119,522 (ACS 2020-2024). Zillow's typical home value was about $416,000 in September 2026, down 5.3% from a year earlier, while the median sale price in August was $427,583.

For tax year 2025 a Wylie home in Collin County and Wylie ISD paid about 1.95% combined (city 0.543438, Wylie ISD 1.1752, Collin County 0.149343, Collin College 0.08122 per $100). On a $425,000 home that is about $8,280 a year, or roughly $690 a month, before exemptions; the Rockwall County piece runs about 1.97% and the Dallas County piece about 2.25%. The city does not offer a general homestead percentage, but the state's $140,000 school homestead exemption applies to owner-occupants and the city gives $30,000 for over-65 and disabled owners.

Look up the exact property on the Collin, Dallas or Rockwall appraisal district site to see its school district and taxing units, since a Wylie address can be zoned to six different ISDs. Then ask the seller for the roof age and any insurance claims, and get a quote for homeowner's insurance before your option period ends.

The lesson in Wylie is to check the address, not just the city name. Wylie ISD serves most of the Collin County side, but parts of the city are zoned to Garland, Rockwall, Plano, Princeton or Community ISD, and each county piece carries a different tax total. Two homes on the same side of town can land in different districts with different tax bills, so pull the appraisal district record for every house you like before you fall in love with it.

About 61% of Wylie homes sold below list price in August 2026 (Zillow), so a sharp first price matters more than a clever one. If your home is in the April 2016 hail footprint, have the roof, gutters and garage door documented, because buyers' inspectors and insurers look hard at hail damage. A roof with paperwork and a clean HVAC service record take two big objections off the table before showings start.
