Theoretical rent increased, caused by the fact that the number of units of the portfolio increased by 5,355 units, from 22,454 (2017) to 27,809 (2018). Furthermore, this increase was largely due to the purchase of the former Delta Lloyd portfolio, rent optimisation and the application of the annual rent increase. Vesteda voluntarily capped the annual average rent increase to CPI plus 2% in 2018, resulting in a like-for-like increase of 2.7% (2017: 2.8%). The loss of rent increased, which was mainly due to the inflow of new complexes.
