How does the DCF method ( Discounted Funding ) work? Cash flow in real estate?

The mechanics of the future: This is how the model calculates

The discounted cash flow (DCF) method for real estate is based on a two-phase analysis. A detailed forecast period (usually 10 years) is examined, and a residual value is then calculated.

1. The basics of the DCF method for real estate

Unlike static methods that assume a "perpetual annuity", the DCF method models each year individually for real estate.

DCF method for real estate, you ask yourself the following questions for each of the next 10 years:

• What is the rent in year 1, year 2, year 5? (Taking into account rent increases or index adjustments).
• When does the roof need to be renovated? (Considering large expenditures in a specific year).
• What is the vacancy rate?

The DCF method for real estate therefore creates a film of the future, not a snapshot of the present. This makes the DCF method for real estate more flexible than any other calculation method.

2. Calculating cash flow for real estate

Cash flow is the money that effectively stays in your pocket. The discounted cash flow (DCF) method for real estate calculates:

Rental income – operating costs – maintenance = net cash flow.

What makes the DCF method special for real estate is its level of detail.

• While a simple return calculation deducts a flat 15% for ancillary costs, with the DCF method you can plan exactly for real estate: "In year 4 we will replace the heating system for 30,000 francs."
• This means that the cash flow in year 4 is significantly lower for real estate using the DCF method than in year 3. These fluctuations are only made visible by the DCF method for real estate .

3. Discounting: The time value of money

Now comes the core of the DCF method for real estate : discounting.

100,000 Swiss francs in income in year 10 are not worth 100,000 francs today. Due to inflation and lost interest (you could have invested the money elsewhere), they are perhaps only worth 70,000 francs today.

The DCF method for real estate uses a discount rate to convert future income to the present day ("present value").

The discount rate used in the DCF method for real estate is composed of:

• Risk-free interest rate: What are the benefits of a German government bond?
• Risk premium: How risky is the property? (Vacancy, poor location, concentration risk).

The higher the risk, the higher the discount rate and the lower the current value in the DCF method for real estate .

4. The residual value

What happens after the 10-year forecast period? The house doesn't simply vanish into thin air.

The discounted cash flow (DCF) method for real estate calculates a sales proceeds (residual value) for the end of year 10. It's treated as if the house were actually sold at that time. This substantial amount is then discounted to the present day.

In the DCF method, the residual value often accounts for over 50% of the total value of real estate. This illustrates the importance of assuming that the house will still be valuable in 10 years.

Advantages of the DCF method in real estate

Why do professionals almost exclusively use the DCF method for real estate ?

• Transparency: Every assumption (rent increase, renovation) must be explicitly stated. The DCF method for real estate forces the appraiser to be transparent.
• Investment planning: You can see exactly when money flows out . The DCF method for real estate is therefore also a liquidity plan.
• Flexibility: The DCF method for real estate can perfectly reflect vacancies in the initial phase (e.g., after construction is completed), which static methods cannot.

Challenges and risks

The DCF method for real estate has a nickname: " Garbage in, Garbage out".

Since the DCF method for real estate is based on forecasts, it is susceptible to manipulation.

• If you make a minimal adjustment to the discount rate in the DCF method for real estate (e.g., by 0.2%), the property value immediately increases by thousands of francs.
• Those who use the DCF method for real estate If overly optimistic rent increases are assumed, the property becomes financially attractive.

DCF method for real estate requires considerable experience and a critical plausibility check of the assumptions. For a simple single-family home, the DCF method is usually overkill and too complex. It is more suited to large apartment buildings and commercial parks.

Comparison: DCF vs. Earned Value

A key difference lies in the perspective. The traditional income approach looks at an "eternal year." The discounted cash flow (DCF) method for real estate looks at a specific timeframe.

If you plan to buy a property, renovate it for five years, and then rent it out at a higher price, only the discounted cash flow (DCF) method for real estate can accurately reflect this increase in value. Static methods fail in this case. Therefore, the DCF method for real estate is the tool for active investors who focus on value addition.

Who uses the DCF method for real estate?

In Switzerland, the DCF method is standard for real estate in the following cases:

• Pension funds and insurance companies.
• Real estate funds.
• Professional appraisers (SIV) for investment properties.

Private individuals rarely encounter the discounted cash flow (DCF) method in real estate , unless they purchase shares in real estate projects (crowdinvesting). In these cases, return forecasts are almost always calculated using the DCF method . Therefore, understanding the underlying logic is worthwhile in order to interpret such prospectuses.

Conclusion

The discounted cash flow (DCF) method for real estate is the most powerful tool in modern valuation. It transforms concrete into mathematics. By mapping and discounting income and expenses over time, the DCF method delivers the fairest value for investment properties. It ruthlessly reveals whether renovation is worthwhile or whether the purchase price will be covered by future rents.

But beware: The DCF method for real estate is sensitive. Small changes to the interest rate parameters can drastically alter the result. Don't trust any DCF calculation whose assumptions (rent growth, discount rate) you haven't verified.
