Will try to answer without delving into whether our unfair rent legislation is good or bad, since that to me seems more of an opinion motivated by politics or greed.
This is simply untrue and the notion of unenforceable or illegal contracts (or clauses) is not unique at all to residential rental contracts.
Off the top of my head: contracts made under duress, old folks tricked/forced out of their legacy, fraudulent contracts, illegal employment clauses, and many other examples can be found. Sometimes the whole contract is invalid and sometimes just specific clauses, like the rent amount in unfair rentals.
Once the possibility of a contract or clause being illegal is established, it’s only logical that it can be disputed and that there are mechanisms to do so.
Saying something along the lines of “if you already signed it, you have to deal with it even if it’s illegal” is a bit naïve since, assuming good faith, it’s in everyone’s interest to keep contracts alive while removing or correcting the illegal parts. Otherwise, it turns a bit into “I only want this contract if it includes the illegal clauses” which is not defensible.
So in essence, disputing a rental contract is simply a mechanism obtain a legal contract, including the price. The fact that it can be disputed after signing recognizes that having a place to live is not optional, many times the same thing is considered for employment contracts.
Interestingly, tenants only get 1 month to dispute rent. After that the price stands, no matter how abusive according to law it is. The first step after a dispute is essentially a negotiation. If that fails, then unfair rent may come into play. If so and if the rent is deemed too high, after adapting to price to something that according to the owner’s documentation will still guarantee them a profit (albeit a lower one) there is no punishment. Other potentially illegal contracts are not reviewed and getting contracts disputed successfully 100s times will yield no consequences for the owner other than time lost (on both sides) and possibly disdain from the public.
Considering this, it seems more like a calculated risk for the owner: unless the contract is under-priced, they are guaranteed a profit no matter what. Even if the initial price was abusive there’s still a huge chance it will stand since very few tenants actually dispute their rent. To be clear, I’m not a proponent of “simply try”, knowingly applying illegal conditions and hope for the best is not morally acceptable IMO.
The rest of the equation is a typical investment scenario: you have known (e.g. laws) and unknown (e.g. evolution of supply/demand) risks and an expected return. Honestly I don’t get all the emotion about it.
Side-note: it seems to me that this is a topic with strong biases at play.
I think this sort of language reduces the value of the exchange. Issuing belittling blanket statements doesn’t make for good discussion. Please don’t take it as an accusation, it is really not meant as one. It is simply an invitation to everyone (myself included) to try to keep discussions focused on what’s relevant
