I beleive housing should be a privately owned venture, at least for suburb housing where the entire plot is included. Outside of that social schemes should purchase/build properties for rental purposes.

Like you said, the housing market is in demand. But how much of that demand is manufactured by landlords purchasing more property to rent versus real buyers looking to buy-to-occupy?

Your argument for cost of maintenance is part of the equation, however the rent costs should be the cost of maintenance and upkeep with a modest margin for investment. However that's not the case. Landlords want to take their cake and eat it. Rent is now the cost of the mortgage, AND maintenance/upkeep AND profit. Its a win for landlords and a lose for renters. If the renter is capable of paying the inflated rental costs on a regular, then they should be owning their own home. The current status-quo is unfair.

Just FYI, I am a home owner. I know the costs of mortgages, the risks that are involved and the maintenance costs of keeping a home running.
