Carla is clearly not afraid of Foreclosures, and sees the opportunity to earn extra $$$$ & higher returns - especially on a well-chosen property in a strong local real-estate market.David is somewhat more risk-averse / conservative and just wants principal & [most] interest back as soon as possible , and is willing to forego some upside to decrease the probability, however low, of any kind of negative eventual outcome...   

Good news is that vacancy rates are usually pretty stable with recessions being good for investors as vacancy rates decrease.

The article is still relevant in the sense that the vacancy rate still remains at roughly the same elevated level (9%+) and if the post & local colleges were enough to absorb the inventory created by the Army & Air Force realignments, then the vacancy rate would expect to decrease - and that has not really transpired.
