An immediate profit does not have to be made for the venture to be viable. If this was the case, there would be very little rental accomodation available in Ireland. Not everybody is out for a quick buck, some of us are in it for the longer term to realise capital appreciation and hopefully some return if rents rise in the future.
I would agree that €70 will not break the bank, but if you're unfortunate enough for your tenants to change three or four times in a year or two, this €280 just simply isn't fair. Another landlord who may be lucky enough to have an original tenant, even though two or three other rooms in the same house have changed hands, would not have to pay a penny. I can't see the logic behind it.
Yes, it's a free market, but if the government want rental accomodation to remain readily available, like it currently is in most areas, they should not impose unfair penalties like this. It's just another thing to discourage people to invest further in this country.
