Answer:
the question is incomplete:
Buildings A and B are similar in size (80,000 and 90,000 square feet, respectively). However, the two buildings differ both in maintenance costs ($23 and $30 per square foot) and rental rates ($100 versus $120 per square foot). At this point, we do not know why these differences exist. Nonetheless, the differences are real and should somehow be accounted for in the analysis of the value of building B using data based on the sale of building A. Building A sold for $462 per square foot, or $36,960,000. This reflects a sales multiple of six times the building’s net operating income (NOI) of $6,160,000 per year and a capitalization rate of 16.67%.
NOI of building A = ($100 x 80,000 ft²) - ($23 x 80,000 ft²) = $6,160,000
NOI of building B = ($120 x 90,000 ft²) - ($30 x 90,000 ft²) = $8,100,000
building B's market value = NOI / capitalization rate = $8,100,000 / 0.1667 = $48,600,000
property value = $48,600,000 / 90,000 ft² = $540 per ft²
