Questions

Frequently asked questions

F-01

Is the DDORF rent estimate a rent index?

No. We have no rent index available to use for Willich. The estimate is a guide, not the local comparative rent under section 558 BGB.

F-02

How accurate is the estimate?

We checked it against 234 calculations using rent indices from 13 cities in the region: the average deviation is 7.7%, and in 80% of cases the rent-index value falls within our ±12.6% range. These reference points were also used to calibrate the model; this is not an independent accuracy test for new apartments.

F-03

What is it calculated from?

From the average net rent according to the census 2022 for the city, from surcharges and deductions for year of construction and living space, which we derive from around 1.300 current rental offers in the region, and from a factor that extrapolates the level of 2022 to today.
