Established-corridor pros and cons

Onion Creek means existing retail, roads, and comparables, less guesswork than a brand-new MUD on bare land. It can also mean infill product on tighter sites. Both are checkable in one visit.

Flood history is a required question here

Parts of the broader Onion Creek watershed have documented flood history. Ask directly which flood zone the specific lot sits in and get the map, not a verbal answer. That single question can be worth more than any incentive.

Not yet verified, what the field visit is for
  • Property tax rate, entry-price areas frequently carry MUD/PID combined rates near or above 3%. We publish no rate until it comes off a rate sheet or district document.
  • HOA dues and what they include.
  • School district and campus assignments, confirmed with the district, not the sales office.
  • Construction activity, amenities, and road access, observed on-site.

Advertised prices are builder claims observed on the date shown, treat every figure as a researched starting point, not a substitute for the numbers the builder puts in writing.
