Buying or selling a home zoned to Sundown?

Inventory in this zone runs thin — it’s a small, settled pocket with only a handful of active listings at any given time, and the I-10 access at Westgreen is hard to beat at these prices. If you want in, alerts matter more here than almost anywhere in Katy. As your real estate buyer’s agent I’ll confirm the assignment on every home we tour, weigh dues, MUD taxes and flood history, and negotiate on your behalf — we’ll agree on how I’m paid up front and in writing.
