Can my landlord increase rent if it is already way above market price?

Rules for rent increases are gone so complicated, its hard to be definitive.

If you're not in a RPZ, the rent review cannot be until 24 months into the tenancy. Maybe the rent review gave the incorrect notice, or was not in the RTB format.

Assuming everything is valid with the notice, AFAIK, a rent increase cannot be above market rate. Market rate does not just mean your apartment block, it could be any apartment block in the general area. Check what is advertised on Daft in your area.

Maybe check with Threshold for their view.

Also consider if you want to have this fight with your LL in a market where finding somewhere else could be a problem. What happens if you win the rent increase battle and your LL then gives notice to terminate because he/she is selling up. Its not a good time to be a tenant right now. Best of luck.

If you think you are paying €200 above the market rate then move.

Statutory rights kick in after 6 months. No lease required for ongoing tenancies. You're no better or worse off not having a new lease every year

You're free of course to request a decrease or ask landlord not to increase the rent but its a LL market at the minute so prob unlikely. Also the government have punished LLs for rewarding good tenants with lower rents by holding these rents for future tenants so theres no real benefit to the LL. The expiry of the lease means nothing unfortunately other than you're free to give notice if you do find a Cheaper place to rent.

Reviewed yes. Absolutely won't be reduced. Why would it ?

Yes but you agreed to it. And have been paying it for 2 years. You're Free to move on if you find cheaper. No landlord is going to reduce rent by that much and they would be crazy to.

There are more landlords stuck with under market value rents which is also unfair.

It would be alot easier to just move into one of the lower rental properties in the building no?

I really don't see you getting anywhere with having the rent reduced.

Then move.

Don't think there's any way you can force the LL to reduce the rent

A LL has to give three examples. If he gave three examples then you and the RTB accepted them. It's very hard to go back two years later and say it was above market rates if you accepted that those were the market rates at the time.

This time he doesn't have to prove market rates. He actually did not have to prove last time either. You are only allowed to increase rent by rates set RPZ calculator.
