@Linkat,
As you may know, we have a similar situation in the Boston area. Condo owners can rent out their units, if they so desire to anyone with the cash. Some potential renters do not have the cash and instead can get a good % of the rent paid through section 8 housing.
As a result, within one condo-building, we have renters who pay their own 100% of the rent, we have renters who pay 50% of their rent ( 50 % paid through section 8 housing), and finally owners, who live in their own units and pay only the regular condo fee.
As the total number of renters increases, the number of owners ( living in the building) decreases, either because they sell their units, or they rent their condos out.
The number of renters in a condo building has a significant effect on the selling price of any unit in the building that should go up for sale. Moreover, the fact that a given percentage of the renters are low income individuals dependent on the government for rent payment, ,greatly influences the market value of any unit up for sale, where potential buyers will want to live in their own units ( and not rent them).
With time, the condo building converts to a 90-100% rental property.
I personally am against rent-stabilized apartments mixed in with property, where other occupants have to pay their full load of rent. Many of the so-called "rent-stabilized" apartments in NY, have values in the $750,000- several million $$ range. These are elevator, doorman properties. Many owners of these rent -stabilized apartments have very low incomes, who appear to be worthy of the rent-stabilized units. However, they could easily sell their properties, reap the profits and move elsewhere. But they don't.
They are one version of the "welfare-tit" population. They're not poor and they 're not deserving. They're welfare-tit suckers.
I'm against section-8 housing, when it depresses the value of any property, that I own.
As far as the situation in NYcity, if the low income folks gain entrance to front door or use the equipment in the fitness rooms, I suggest that many of the high end folks will move out ( sell or rent their units). If it were me, I'd do the same thing.
The only people who think the above mentioned arrangement regarding diversity among social and economic classes is just, are the crazy democratic liberals... the so-called proponents of the welfare-tit society.
