“…Various researchers have examined vacancy; those interested in obsolescence and depreciation (Baum, 1991(Baum, , 1993Baum & McElhinney, 1997;Dunse et al, 2002;Andrew & Pitt, 2006;Crosby & Devaney 2006;Crosby et al 2011); those interested in the adaptation of vacant properties (Barlow & Gann, 1996;Beauregard, 2006;Kincaid, 2002;Heath 2001;Geraedts & van der Voordt, 2003;Agre, 2005;Langston et al, 2008;Remoy, 2010;Remoy and Wilkinson, 2012;Wilkinson and Read, 2011) those who want to map the characteristics of vacancy (Myers & Wyatt, 2004;Katyoka & Wyatt, 2008;Remoy H & Koppels, 2009); those who model the cyclical behaviour of the economy and property (Ball 2003;Barras, 2009;Wheaton 1999); and those who reflect on the medium to long-term rental adjustment process (Blank & Winnick, 1953;Wincott, 1997;Voith & Crone, 1988;Crone, 1989;Grenadier, 1995;Pissarides, 2000Pissarides, , 2005Sanderson, et al, 2006;Miceli & Sirmans, 2013).
