The LIHTC projects completed in the early to mid-2000s may have contributed to the neighborhood's ability to maintain a diverse population and support lower-income residents, despite median income fluctuations over the past decade.

Montclare's LIHTC-funded affordable housing inventory represents a significant investment in the community. The 283 affordable units, focusing on efficiencies and one-bedroom apartments, likely cater to smaller households and seniors. These LIHTC projects, developed primarily in the 2000s, have likely played a role in maintaining the area's diversity and supporting lower-income residents amidst demographic changes. While the current inventory may not fully meet the estimated affordable housing needs of the community, it provides a foundation for addressing housing affordability in Montclare.
