Two Amsterdam tenants had great success in reporting their landlord to the Huurcommissie rent tribunal for charging them exorbitant rent. The Huurcommissie ordered the landlord to lower the rent for a small, leaky, drafty room on Keizersgracht from 1,950 euros to temporarily 95 euros per month. The rent for another room in the same building was lowered from 1,200 euros to temporarily 93 euros.
You just showed why prices would go up if rent were taxed that way (and why the prices are so high at the moment). No one thinks a small flat is worth 1500€/month (or what have you), but they need a place to live near their job. So they’ll pay whatever it costs. Same with deregulated health care, like in the US.
Also, for what it’s worth. Even without the construction costs and without any profit margin landlords must pay for home repairs. I don’t think 5% would even cover that
Taxes absolutely don’t effect market prices in such cases/markets. Because if your are saying that rent taxes would just fall on tenants (basically increasing rent) then landlords are stupid now because they could obviously charge more rent.
It’s like saying McDonald’s paying employees more would result in pricier burgers - it simply wouldn’t bcs McD is already charging the absolute max it can in given circumstances. It would however lower their profit margin. And still, anything resulting in real profit is still worth doing (that’s why we have McD franchises in Europe too). Or like saying giving a tax exemption to McD would lower the price or burgers - it wouldn’t, price is market determined and not in direct correlation with costs or taxes.
Where what your are saying is true is in markets with cost-based prices (ie minimal/competitive profit margins). In case of real estate that would mean the majority of rent wound go in repairs or upgrades. Which is not true for the last century, but RE yields are determined and tracked based on rent. So if I want to double my property’s value & have to double the rent. And since people need to live somewhere, they have to pay. If yields are not above market (like 10y local govies), money moves out of RE and into financial markets.
