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 ...
95€ temporarily until the defects are fixed. Then the 20qm room is worth a rent of 477€.
The Huurcommissie scored the appointment on a point scale, and determined the reasonable rental price should have been 476.85 euros per month. The tribunal then noted that the tenant was unable to lock their own bedroom. Additionally, the wood-framed kitchen skylight had a 10 millimeter crack in it, causing drafts, and the toilet tank in a shared bathroom was leaking.
The tribunal further lowered the rent to 95.37 euros until the damage is fixed, saying it could find no evidence the landlord actually tried to fix the problems. This can gradually increase as repairs are carried out to the maximum of just under 477 euros. The reduction was also backdated to September 1 from the ruling, which was filed at the end of December and published more recently. As a result, the landlord must repay the overpaid rent in the intervening months.
The argument is: if your rent is that cheap, you probably have a side deal going on (like extra pay or work for housing) to avoid taxes and/or social security contributions.
I'm not saying the present system is great, I'm just explaining it and unfortunately some people indeed try "save" taxes that way.
Not trying to defend the decision, but as far as I know, the reasoning is that if you charge significantly less than you could, it might be because you have other undisclosed agreements with the tenants, like them doing some extra chores for you, repairing the flat or something else.
This way, you could avoid a lot of taxes. The sentence also doesn't seem to be a fine in the narrow sense, but rather a demand of additional taxes. If I'm not mistaken, it's perfectly legal to charge very little for a flat, but you still have to pay taxes as if you would have rented it out for a regular price.
The process of getting house/room in many areas in the Netherlands is full of bureaucracy. We can't simply get a place and move there straight away. We need to register with the local councils and the requirements and regulations each local councils vary between places. Many times, it becomes catch-22 situation, e.g. you need to already have a job, but to get a job you need to register. That's why some people are desperate enough that they move to shitty places.
Because housing is basically extortion in big European cities. It's like there's a global conspiracy to stop building new housing and lower interest rates so real estate value skyrocket.
But then the price goes up again :( It's only €95 because of the problems in the room. When fixed it goes to about €470, which is still all right I guess for that location in Amsterdam.
