I asked about your hypothetical scenario.That could differ from agreement to agreement
In the real world it doesn't. You're confusing socially desirable situation, with the real world.But taking a standard 12 month agreement (for the price of the rent, and not the occupancy) then any agreement should demonstrate that any increases thereafter are proportionate, sustainable and justified.
You've used the word 'should'.
Either base your arguments on fact & reality, or I'll leave you in peace to get back to your pet unicorn.
In your scenario:
At the end of the agreement, the tenant just says they'll move out, unless rent is reduced. There is no guarantee of rent for the landlord.The tenant in the €1300 property would presumably like to see their rent reduced to €1150 too - but tough, €1300 is the price agreed so pay up.
