Something has to be done.
My friend just got a 29% rent increase this year.
Their apartment has not been modernised or new fittings for 10 years.
Average rent increase this year for the area is 20%.
There has to be incentives introduced to rapidly build more affordable houses, but any policy that has a negative impact on house prices is a loser to many important voting bases.
Rent control in the short term might have to be done to reign in exploitative landlords.
