The purchase price factor is a key figure in real estate valuation that describes the relationship between the purchase price and the annual net cold rent.
Formula:
Purchase price factor = purchase price / annual net cold rent
Example:
A house costs €1,000,000, the annual rent is €50,000
→ Purchase price factor = 20.
The lower the purchase price factor, the faster the investment is amortized through rental income.
Calculating the purchase price factor - step by step
Formula and input variables
To calculate the purchase price factor of a property, you need
- Purchase price of the property
- Net annual rent
Examples from practice
| City | Property type | Purchase price (€) | Annual rent (€) | Purchase price factor |
|---|---|---|---|---|
| Magdeburg | Apartment building | 1.000.000 | 55.000 | 18,18 |
| Bremen | Commercial property | 2.500.000 | 125.000 | 20,00 |
The purchase price factor in Magdeburg is 18.18, while the purchase price factor in Bremen is 20. This shows that regional differences and property types have a considerable influence on the yield.
