In January 2018 Neltex Sports Group hired Arez Ardalani as the new head coach of Texas United. Signings of new players saw plenty of FC Dallas college based players added to the roster. The Texans started the season very strong with a 5–0 victory against FC Cleburne at home and a 3–2 victory against OKC Energy U23 away. After multiple away games and a tough schedule the Texans were able to set the franchise record at 5–6–3, with multiple team and individual honors. As a result of the successful season many players were invited to or signed professional contracts with USL organizations such as Pittsburgh Riverhounds SC and North Texas SC.

Texas United started its 2019 season with early spring exhibitions against USL Championship clubs such as El Paso Locomotive FC, OKC Energy, and Swope Park Rangers. After the spring season Texas United moved forward with signing multiple trialist that impressed during the exhibition matches. The club had its 2019 season opener against Houston Dynamo USL 2 franchise Brazos Valley Cavalry FC.

Spring season play began in January with Texas United playing El Paso Locomotive FC. Before the beginning of the 2020 USL Championship season the squad went down to play the Austin Bold FC. The USL League 2 season was cancelled due to COVID-19.

2021 was a historic season for Texas United. The team made playoffs for the first time in club history and posted a franchise record of 6–5–3.

Texas United won their first trophy in 2022 by clinching the USL2 MidSouth Division championship in historic fashion. The club went undefeated with a 9–0–5 record, the only non-MLS club to do so in the division’s 20-year history. Texas United finished the season ranked 12th out of 113 clubs in the regular season’s final power rankings. Arez Ardalani left the club after the season, ending his era which took the Texas United project from a low tier USL 2 club to a top 15 tier 1 club.
