Sachse Realtor, planned with real numbers.

Sachse is a city of about 32,834 people (July 2025 Census estimate) that straddles the Dallas and Collin county line, with SH 78 and the President George Bush Turnpike as its main roads. Most of its housing sits in established neighborhoods such as Woodbridge, which spans many phases on the city's subdivision map. Zillow's typical home value was about $428,000 in September 2026, down from about $441,000 a year earlier, and homes took a median of 61 days to go pending.

For tax year 2025, a Sachse home in Dallas County paid about 2.36% combined (city 0.650416, Garland ISD 1.1709, Dallas County 0.2155, Parkland Hospital 0.212, Dallas College 0.106575 per $100), while a Collin County home paid about 2.06% (city, Wylie ISD 1.1752, Collin County 0.149343, Collin College 0.08122). On a $428,000 home that is about $10,080 a year (roughly $840 a month) on the Dallas County side and about $8,800 a year (roughly $733 a month) on the Collin County side, before exemptions. The city offers a $50,000 exemption for owners 65 and older or disabled, on top of the state's $140,000 school homestead exemption.

Compare homes by the full monthly payment, since the Dallas County side ran about 2.36% and the Collin County side about 2.06% in tax year 2025. Starting water service takes at least 24 business hours after the city gets your application, ID and proof of residency, so submit it a few days before move-in.

The lesson in Sachse is that the county line decides both your school district and your tax bill. Dallas County homes are in Garland ISD and paid about 2.36% combined for tax year 2025, while Collin County homes are in Wylie ISD and paid about 2.06%, roughly $1,280 a year less on a $428,000 home. Ask for the appraisal district record on any home you are considering, because the same price can mean a very different monthly payment.

Sachse homes took a median of 61 days to go pending in September 2026, so plan for about two months on market and price from the first day rather than testing high. Tell buyers your county and school district up front, because a Collin County address with the lower combined tax rate is a real selling point in the monthly payment. On homes from the 1990s and 2000s, show recent roof, HVAC and water heater work with receipts; those are the items buyers in Woodbridge and similar neighborhoods ask about first.
