Buying or selling a home zoned to McElwain?

Elyson buyers are mostly comparing new-build inventory against nearly-new resales, and the B-87 neighborhood school is a real tiebreaker in that comparison — but the junior-high and high-school answer changes by section out here, and I confirm it with the district before we fall for a floor plan. 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.
