If you were renting out at €1,300 for a two bed in Cork City and your tenant has left, you'd be thinking based on Daft, that you'd get €2,300 when you rent now. But looking at the Register, that would be a huge red flag for the RTB as €1,500 seems to be about the rough average.
So to be safe, you'd need to rent for that. That is an extra €1,000 a year net after tax or thereabouts and you've granted a 6 year tenancy or a permanent one. You're getting peanuts for locking yourself into a much riskier situation.
There won't be a meaningful increase at year 6 either. That'll have to be based on the Register as well.
Plus a house with a €1,300 rent is massively devalued if you have to sell with the tenant in situ.
