Because tenants rights are poor? The difference in safety felt between owning and renting is related to perception of tenants rights. I think they (the difference and the rights) vary accordingly worldwide.
It's difficult isn't it? You need to somehow reconcile the fact that it's not the tenant's home with their desire to treat it like it is.
I've had to fight to get basic repairs and redecoration work done. In some of these cases I've still had a battle despite funding them myself!
I think something you could probably address is the lack of security with tenancies. In the UK, after the initial fixed period of an AST, it's very easy for either party to terminate the lease. I'd prefer for this to be tipped in favour of the tenant, so that they can be flexible and leave if necessary - but they're not also in danger of homelessness at very short notice.
