Is this Notice of Termination valid?

https://www.rtb.ie/ending-a-tenancy/notices-of-termination

Minimum notice required from your landlord would appear to be 180 days.

If you have a fixed term lease it might not be possible until the end of the fixed term depending on whether the lease had a relevant break clause but it would be at least the statutory 180 day minimum.

Any notice for the reason of wanting to sell the property would also need an accompanying statutory declaration in order to be valid.

As @ted1 has pointed out you haven't actually received any notice of termination yet, just a heads up that one might be on the way.

If you get a valid termination notice because the owner is selling you would just leave within the 6 months of notice. I wouldn't worry about who is buying the place it isn't really relevant. If it isn't sold within 9 months of you leaving or it's listed for rent again by the same owner you can report them to the RTB/request to move back in at the same rent. It's possible your request made them sell up if they aren't tax compliant etc. but there's nothing you can do about that now so no point thinking about it. I'd start looking for another place as the letting agent suggested, it might take a while to find in current situation.

You do not need to do anything yet because you have not received any notice, valid or not. WHEN you receive a notice of termination then the clock starts. You can of course check that the notice is valid with the RTB but even if it is not the landlord is serious about getting you out. At the moment the letting agent are chancing their arm hoping you will leave.

Not if he has to pay CGT and Theres a possibility of relief been giving in the not so far future

Seriously, OP, it sounds like you're putting 2 and 2 together and getting 10.

Just wait and see what happens next. You haven't been given any notice to leave, the apartment *clearly* hasn't been sold and it sounds like you've been paying below market rent since you moved in. Keep quiet and sit tight, is my advice.

Quite literally anyone thinking of selling up and trying to make themselves feel better about it.

My own brother described his wife selling the house I'd rented off her for 9 years and me having to move home to my parents last year as "a new chapter".

“Animated my fervour” that’s a super phrase. If he does sell up, I’ll rent you a room in my gaff, you sound like a scream. 🙂

Whatever about the legalities or otherwise of the situation here, I can't get past how the OP has such huge disdain for the letting agent by using words like slippery, nasty, unscrupulous and even "scum of the earth" to describe him, when the agent has actually doing OP a huge favour by facilitating an arrangement that saves OP somewhere from €400 to €500 a month, or up to €6,000 a year.

And repeated mention of an "illegitimate" rent increase last year suggests that OP was paying even less for his first year or so of the tenancy, potentially saving up to €600 or even more per month on market rates for similar properties in the area.

Personally I reckon I'd be keeping the head down and saying nothing, and continuing to save €500 per month with the current arrangement, instead of rocking the boat over potentially claiming a tax credit that's only worth €500 a year.

That clause is not compliant with Part 4 of the Residential Tenancies Act and would therefore be void. Your landlord would need to issue you notice as required by the Act. A two-month notice would be invalid regardless of what your tenancy agreement says; your agreement doesn't override the law.

You are also not responsible for repairs to the property or the provided furnishings or appliances; that is the responsibility of the landlord. If you cause damage beyond ordinary wear and tear, you could ultimately be held responsible for it and have to pay the cost (or have it deducted from your deposit), but your landlord would still be the one who would have to arrange and pay for any repairs up front.

I registered i dont know how many tenants over the years and a couple of times i had accusations that I hadnt registered them. Last one was under the impression that i couldnt raise the rent on them after the previous tenant sent them a letter stating the rent they used to pay. So they asked the RTB, who said that I was not allowed to increase the rent by that amount, which I actually was allowed to under their rules at the time. Then they accused me of not being registered, accompanied by a similar response to the quoted mail, to their queries from the RTB. The funny thing is that I got a letter from the RTB a few weeks ago telling me to re-register tenants. They can go fcuk themselves at this point as i no longer even own the property.

because some people are dodgy. And wilL issue out any documents that favour them

in hope that no one notices

O/P the way things are going, it looks like you will find yourself on the side of the road before long. In case you hadn't noticed, finding an alternative rental will be very difficult.
