This is the part most buyers here do not know, and it changes who qualifies.
USDA income limits are set by county, and Rockwall County's 2026 limit is approximately $119,700 for a household of 1–4 people and $158,000 for 5–8. That is materially higher than Dallas or Tarrant County, where the same limit sits near $97,200. A household earning $110,000 would be over the line in Garland or Mesquite and comfortably under it in Royse City.
Two things worth knowing about how USDA counts income. First, it counts household income — every adult in the home, not only the borrowers on the loan. Second, it allows deductions that often bring people back under the cap: $480 per dependent child under 18, documented childcare costs for children under 12, and certain medical expenses for elderly or disabled household members.
The practical upshot is that plenty of Rockwall County buyers assume they earn too much and never ask. If your gross income looks slightly over, call or text me at 469-545-7180 and let me run the actual calculation before you write USDA off.
