They OP said they raised the rent in Jan 2023, and again in March 2024. What the rent was years ago is of no consequence now, just the amount raised since the previous rent. Perhaps they might have been eligible to raise by more in 2023, but that ship has long sailed.doubt €150 per month equates to 2% - my point is that the breach may not be as high as it initially looks if you did not increase for a number of years (which seems to be the case with that poster for the first increase anyway).
Why would they choose to run an export of all where increase >2% when another couple of minutes enhancing the query would identify those who are more likely in breach? I've yet to hear of someone who is clearly in compliance get such a letter.I think that this is a mail merge - every landlord with a tenancy showing an increase above 2% is being emailed.
Also to note, no organisation of that scale is doing mail merges any more....technology has moved on.
