Final answer:
The estimated value of the building is $530,000.
Step-by-step explanation:
To estimate the value of the building, we can use the formula for the rate of return on investment (ROI). The formula is:
ROI = Net operating income / Value of the building
We know the net operating income is $47,700 per year and the rate of return is 9%. Rearranging the formula, we can solve for the value of the building:
Value of the building = Net operating income / ROI
Substituting the values into the equation:
Value of the building = $47,700 / 0.09 = $530,000
Therefore, the estimated value of the building is $530,000.
