"With temporary and furnished rentals, loopholes in tenancy law are exploited and horrendous sums are demanded," explained Biedermann. "This quickly results in a total rent of 3,500 euros for 80 square meters. This is not an isolated case in Neukölln." According to the district councillor, this practice is getting out of hand and is leading to the proportion of affordable housing becoming ever smaller. "People on low and middle incomes are finding it increasingly difficult to find an apartment. We will restrict this practice in milieu protection areas and consistently pursue unauthorized rentals." The council is confident that the new administrative practice will stand up to any judicial review. The temporary letting of furnished apartments is also increasing in other Berlin districts.
