Key Takeaway: Market demand indicators point strongly towards the 1-Bedroom configurations as the primary entry point for this development. The 2-Bedroom units maintain a selective position with a tighter inventory profile, yet they still command a higher average price per square foot than the smaller layouts.

This competitive pricing structure suggests the development serves as a strategic choice for seekers prioritizing value within a high-demand central area.
