Alamo Heights is under two square miles and holds around seven thousand residents, entirely surrounded by San Antonio. On paper that sounds like a hard market to advertise into. In practice it is one of the easiest, because the radius is tiny, the household income is among the highest in the metro, and the people inside it spend locally.
The catch is that this audience is not impressed easily. In 78209, a business with dated photography and a half-finished profile reads as second-tier before anyone reads a word. The work here is less about volume and more about looking exactly as good as the price you charge.
