A reason downtown Houston may “suck” is because there are too few homes and thus it becomes a wasteland on the weekends and evenings. Mixed use districts with high density of residential will draw in stores, nightlife venues, and restaurants. It will also drive demand for bike and mass transit.

Moreover, there are many urban downtowns that don’t “suck’, such as Boston and NYC that are still facing a challenging commercial real estate market. Additional residential in this metros will be quickly snapped up and drive demand for nearby offices.
