When is the income approach used for real estate?

The investors' playing field: Where method reigns

1. The classic apartment building (rental house)

The prime example of the application of the income approach to real estate is the multi-family house.

Whether it's three apartments or thirty : The buyer doesn't acquire the property to live in all the apartments simultaneously. He buys the rental income.

Therefore, his primary interest is not in the construction costs (the building's structure), but in its rental income. The income approach to real estate valuation is the only viable option here. It compares the annual rental income to the purchase price. Banks finance such properties almost exclusively using the income approach .

2. Commercial and office properties

This becomes even clearer in the case of offices, shopping centers, or warehouses.

Here, the building structure is often functional and "cheap" (concrete shell). The value arises solely from the tenant (e.g., a solvent insurance company or a supermarket).

The income approach to real estate valuation is the only valid tool here. An empty office building has a disastrously low value according to the income approach , even if it is brand new, because it lacks income.

3. Mixed-use properties

Many houses in Swiss cities have a shop on the ground floor and apartments above.

The income approach is also used for real estate valuation here . Sometimes it is combined with the real estate valuation method (mixed valuation method), but the income component usually dominates, as the expected return is paramount.

How does the income approach to valuation work for real estate?

To understand when it is applied, one must understand the logic. The income approach to real estate valuation is based on a simple but powerful formula:

Income value = Net rental income ÷ Capitalization rate x 100

Let's briefly break down the components of the income approach to real estate valuation :

• Net rental income: This is the annual rent minus operating expenses (administration, maintenance, reserves). When using the income approach to property valuation , it is crucial whether these rents are sustainable (market rent vs. actual rent).
• Capitalization rate (cap rate): This is the leverage. It consists of the risk-free interest rate (e.g., government bonds) plus premiums for the risk of the property (vacancy, illiquidity, age).

When interest rates rise, the capitalization rate also rises. Since it appears in the denominator, the result of the income approach to real estate valuation immediately decreases. This makes the method extremely sensitive to interest rate fluctuations .

Demarcation: When is it NOT applied?

It is equally important to know where the income approach to real estate valuation is inappropriate.

The owner-occupied single-family home

When you buy a house for yourself and your family, you're paying for emotions, security, and the garden. You're not earning rent.

Therefore, the income approach is unsuitable for real estate valuation in this case. If it were applied (with hypothetical rents), the resulting value would often be much lower than the market price. Why? Because homeowners are willing to pay for "characteristic" properties that don't generate a return. Comparative valuation methods (hedonic valuation) are used here, not the income approach for real estate .

Public buildings and special projects

School buildings, churches, or train stations often do not generate market-rate rents. The income approach to real estate valuation is unsuitable in these cases . Instead, the actual value (construction costs) is used.

Building land

Undeveloped land generates no income (except perhaps rent, which is minimal). The income approach to real estate valuation cannot be directly applied here; instead, the so-called "residual value method" (a backward calculation based on the planned new construction), which is a variation of the income approach for real estate, is used .

The dynamics: DCF as a modern sister

In the world of professional investors (pension funds), a refined form of the income approach is often used for real estate : the discounted cash flow (DCF) method. Cash Flow Method (DCF).

• Classic income approach for real estate: Looks at a static year (perpetual annuity).
• DCF method: Looks dynamically into the future (e.g., 10 years). It takes into account that rents might rise in 3 years or that renovations might be necessary in 5 years.

For smaller multi-family houses, however, the classic income approach to real estate valuation remains the standard, as it is more transparent and less susceptible to manipulation of forecasts.

Why the income approach to real estate is important for you

Even if you are not a major investor, you will encounter the income approach to real estate .

• Buying a granny flat: Do you want to buy a two-family house and rent out part of it? Then the bank will value the rented part using the income approach to real estate valuation .
• Inheritance division: When an estate includes a small apartment building, heirs often dispute its value. The income approach to real estate valuation provides the fairest value in this case, as it demonstrates the income generated by the inheritance .
• Beware of "dream returns": Sellers often lure buyers with high gross returns. A proper calculation using the income approach for real estate reveals when high maintenance costs eat up the net return. The income approach for real estate is the lie detector for property listings.

How digital tools help

Calculating the income approach to property valuation requires data: What is the market rent? What are the average operating costs? What is the discounted interest rate?

As a layperson, you often lack these parameters.

Platforms like heyloft.ch provide support here .

The digital assistant "Loft" can help you to validate the variables of the income approach to real estate valuation .

• Market rent check: Loft knows what's being rented in the area. If you're using the income approach for properties with excessively high rents, the data will warn you.
• Risk assessment: Loft provides data on vacancies in the neighborhood. This helps you to realistically set the capitalization rate in the income approach for real estate .
• Independence: Loft calculates objectively. She has no interest in manipulating the income approach to real estate valuation , as sellers sometimes do.

Conclusion

The income approach to real estate is the tool of choice whenever a property is intended to generate income. It is used for apartment buildings, commercial properties, and investment properties. It disregards emotional value and focuses solely on cash flow. Anyone wanting to buy or appraise an income-generating property must not consider its intrinsic value but must use the income approach .

Understand the leverage effect: Small changes in rents or interest rates have a massive impact on the final value in the income approach to real estate valuation . Therefore, don't rely on simplistic calculations.
