Answer

The library has a number of books and ebooks available on this topic, which can be found by searching in the library catalog (BobCat) for the topic of real estate feasibility. Two examples of titles that might be of interest: 

Real estate development: Principles and processes (2015)

Financial feasibility studies for property development: Theory and practice (2013)

To find demographics and housing statistics, mapping resources like SimplyAnalytics and PolicyMap, linked from the Real Estate Research Guide, can be useful for assessing supply and demand. In addition, the market reports page of that same research guide provides links to a number of residential and commercial firms producing current reports on various major markets around the world.
