Income Approach
Appraisers use three different methods to estimate the value of real estate. They
are the income approach, the sales comparison approach and the cost approach.
The sales comparison approach is considered the best method for appraising single
family homes. The cost approach is used to appraise special purpose buildings such
as churches, schools and public buildings. The income approach is used to estimate
the market value of income producing properties such as office buildings, warehouses,
apartment buildings and shopping centers. When adequate financial data for recent
sales of similar income producing properties is unavailable, appraisers may use a
utilize all three approaches.
The following is a brief and simplified summary of the income approach. The income
approach is used when reliable financial data is available for recent sales of similar
income properties in a given market place. A properties net operating income and
sales price are used to calculate a capitalization rate for the sale of each similar property
in a given area or market place. If sufficient sales of similar income properties are
available, a market cap rate can be determined by averaging the cap rate values
from the individual sales. Appraisers will sometimes use a market gross rent
multiplier or gross income multiplier instead of a cap rate to estimate the value of
single-family rentals and 2 units.
Net operating income is calculated like this.
1) The appraiser first estimates the annual potential gross income for a property.
This involves estimating how much rent each unit could generate in the current
market place. The rental rates being charged by the current owner may be too
low and may not reflect potential market rental rates. Appraisers study the
current market place to estimate potential rental rates.
2) The appraiser then calculates an effective gross income for the property by
reducing the annual potential gross income by a vacancy allowance amount.
The vacancy allowance amount is determined by current market rental
conditions for the type of property being analyzed.
3) Miscellaneous income such as parking fees, laundry and vending receipts are
added to the income.
4) Operating expenses are deducted from the effective gross income to determine
the annual net operating income for the property.
Income
Gross Rents Possible 100,000
Other Income 3,000
Potential Gross Income 103,000
Less Vacancy Amount 2,000
Effective Gross Income 101,000
Less Operating Expenses 31,000
Net Operating Income 70,000
Once the net operating is determined, a capitalization rate is calculated for the property.
If the above property sold for $670,000 , the cap rate is calculated like this.
NOI 70,000
Capitalization Rate = ---------------- = --------------- = .1045 X 100 = 10.45 Rounded
Sales Price 670,000
We have several other similar income properties that the have recently sold in the same
area. There financial data is summarized below.
Comparable No. Sales Price Net Operating Income Capitalization Rate
1 670,000 70,000 10.45
2 730,000 75,000 10.27
3 625,000 65,000 10.40
4 705,000 77,000 10.92
5 780,000 80,000 10.25
We calculate a market cap rate by averaging the individual cap rate data. The market
cap rate for the above data equals 10.46 rounded. The appraiser would estimate the
value of a similar income property like this. He would go through the procedure above to
calculate the net operating income for the property in question. Lets assume that the
net operating income is equal to 73,000. He would use the following formula to calculate
the market value
Net Operating Income 73,000
Estimated Market Value = ------------------------------ = ---------- = $697,897
Capitalization Rate .1046
It should be noted that recent sales of similar property types may be unavailable or very
infrequent. For example, it may be difficult to calculate a market cap rate for shopping
centers since there may be no recent sales.
