题型：单项选择题

John Williams wants to purchase an apartment complex. The complex consists of 75 units each renting for $700 per month. The estimated vacancy and collection loss rate is 7 percent. The insurance for the building is $40000 annually and taxes are $22000 annually. Utilities are $18000 and the maintenance expense is $29000.

Assume a market cap rate of 11 percent. Recent sales of nearby apartment complexes have resulted in the following information.

Characteristics Units Slope Coefficient in $per Unit

Proximity to downtown In miles -350000

Vacancy rate Percentage - 50000

Building size Units + 75000

Williams’ proposed apartment complex is 4 miles away from downtown and has an estimated vacancy rate of 6 percent.

Using the income approach, the value of Williams’ apartment complex is:（）

A. $5727273.

B. $4525455.

C. $4335455.
