The depot is 5-10% of the value of the apt.
You pay lower rent.
You have a say in the building expenses.
We lived for several years in a cooperative building in Geneva where we'd had to buy 'shares' rather than pay a standard deposit. Although in theory the shares would earned interest in reality the Cooperative statutes reserved the right to spend any interest earned on the upkeep and maintenance of its buildings.
Although our building was brand new and didn't require any, the other buildings were decades old and all urgently required major refurbishing. So, we got nothing extra after ten years and we had a bit of a struggle getting our share money back as well.
Read the small print!!!!
Sadly many do not know they are going to have problems until they move out. Cooperatives have their own rules and the return of the deposits falls under whatever is in the contract.
Fortunately we had read the statutes carefully before signing up and could point out that the shares were tied to the appartment and the rules clearly said that the new occupant had to buy our shares when they took over the lease.
I would imagine they simply thought they could issue new shares for the new tenants and use the extra interest from them as more funds for their refurbishing programme.
The committee members were all elderly men and I doubt they really understood the system their accountant had set up when that particular Cooperative was established in the seventies.
We got our funds back with a couple of months (which was quite rapid compared to the time some agents take), so I didn't enquire further into it.
