Thank you for this excellent article.
It hits the nail on the head.
Owners and tenants flee and professionals do not want to provide services to such buildings, bringing down the value of the schemes.
The wrong people get blamed for the problem, because the root cause of intimidation and nuisance caused by disadvantaged people is very difficult to fix.
Home owners are self-interested economic actors, not service providers. Successful policy treats them as such.
Strata schemes always have power imbalances, and nuisance and intimidation is leveraged by the powerful to harass the weak.
You will see from my posts in here that I had this problem. Not anymore – this year 20 tenants were asked to move out and their units renovated, attracting a different clientele!
