Rowlett Realtor, planned with real numbers.

Rowlett is a city of about 67,890 people (July 2025 Census estimate) on the shores of Lake Ray Hubbard, split between Dallas and Rockwall counties. The President George Bush Turnpike, I-30 and Lakeview Parkway (SH 66) carry drivers, and the Downtown Rowlett station on DART's Blue Line connects riders to Dallas. Zillow put the median sale price at about $376,000 in August 2026, but homes took a median of 51 days to go pending in September 2026.

For tax year 2025, a Rowlett home in Dallas County paid about 2.51% combined (city 0.807891, Garland ISD 1.1709, Dallas County 0.2155, Parkland Hospital 0.212, Dallas College 0.106575 per $100), while the Rockwall County part with Rockwall ISD paid about 2.13%. On a $376,000 Dallas County home that is about $9,450 a year, or roughly $787 a month, before exemptions. The city kept its $0.807891 rate for the 2026 tax year, and the state's $140,000 school homestead exemption saves about $1,640 a year in Garland ISD.

Check which county and school district the address is in, since the Dallas County side with Garland ISD carried about 2.51% in tax year 2025 versus about 2.13% on the Rockwall County side. In new communities, ask whether the lot is in a PID or TIRZ assessment area and add that cost to your monthly math.

The lesson in Rowlett is that the county line changes your tax bill by a lot. A home in the Dallas County part with Garland ISD paid about 2.51% combined for tax year 2025, while the Rockwall County part with Rockwall ISD paid about 2.13%, a gap of roughly $1,450 a year on a $376,000 home. Two similar homes on either side of that line should not carry the same price in your head, so compare the full monthly payment, not just the list price.

Rowlett homes took a median of 51 days to go pending in September 2026 and sold for about 97.6% of list in August, so plan for a longer runway than the busier suburbs and price with that in mind. Buyers here compare resales with builder incentives in Bayside and Trails at Cottonwood Creek, so fix inspection items before you list: roof, HVAC, water heater age and any foundation movement on clay soil. If your home has a lake view or lake access, show it in the first photo, because that is the one thing new construction down the street often cannot match.
