“…When reviewing various studies conducted over time, Pekdemir (2004, 2006) categorized determinants into four categories: econometric factors, building characteristics, locational features, and contract terms. Several studies conducted in diverse contexts have highlighted the influences of building characteristics and locational features on office rents (for example, Mills, 1992;Bollinger et al, 1998;Brennan et al, 1984;Clapp, 1980a, b;Dunse and Jones, 1998;Slade, 2000;Fuerst, 2007;Pekdemir, 2004, 2006;Ozus, 2009;Simon et al, 2015;Silva, 2016;Tomonidie, 2016;Bera and Uyar, 2019). In terms of quality, commercial office properties are commonly grouped into different classes, such as A, B, C and D (Nase et al, 2013), with Class A being considered the best, and class D the least desirable (Glascock et al, 1990).…”
