Real advantages

DeKalb offers genuinely affordable housing, a real, current NIU enrollment rebound, Illinois's simple flat state income tax with its full retirement-income exemption, and a real, distinct 19th-century industrial-heritage identity.

Real tradeoffs

DeKalb's real, substantial decade-scale population decline (roughly -8%) has not clearly reversed; its effective property tax rate (2.44%-2.45%) runs above Illinois's already-high statewide average; and its crime rate runs genuinely elevated (safer than only ~6% of Illinois communities).

The net read

For affordability-focused buyers connected to NIU or drawn to DeKalb's distinct heritage identity who budget honestly for its real tax and crime picture, DeKalb's advantages are real. For buyers prioritizing population growth momentum or the lowest crime rate, other Illinois Tier A markets in this project may fit better.
