Same is happening here in the UK. Due to the lack of social housing, the rental market is now private landlords but due to ever more restrictive tenants rights and now rapidly rising interest rates they are bailing out en mass. I'm not saying tenants shouldn't have rights but when it's so difficult to evict a tenant when they haven't paid rent for months, sometimes since they took occupancy, it makes being a landlord much less appealing. Some tenants now are serial non payers, just moving from property to property and never paying rent, just moving out before the eviction notice is about to be enforced and often leaving the place wrecked. Then because they have no fixed address it's virtually impossible to get them into court for the unpaid rent and damage.
Successive governments have never managed to resolve this problem, either due to lack of political will or because the cost of rebuilding the social housing stock is too expensive, who knows. It seems evident though, that there are now a hardcore of people who just want an easy life on welfare payments, living in cheap housing and a lifestyle of never wanting to work.
