Resident vs non resident landlord

Hi all,

From what I can see, is it right that I am potentially better off, tax-wise, being a non resident than a resident landlord?

Take the following scenarios
1. Working in Ireland. Earning 70k a year, euro. Renting a place for 2k. Rental income is taxed as marginal, >50%. Take home income is <1k.
2. Working in UK/non-Ireland EU country. Earning 70k a year, euro, or equivalent. Renting a place for 2k. Rental income is taxed at 20%, take home is 1600.

Am I missing something here? I know the caveat is all other things being equal in the 2nd scenario

Would the rental income not also be taxable in the second country, minus the tax paid in Ireland assuming a double taxation agreement is in place ? I would double check that.
