at 600pm pushing 5% gross,
is not too shabby compared to elsewhere in the country
if it's on the city side of garryowen, I'd say rentability shouldn't be a problem.
capital appreciation doesn't seem to happen in Limerick as much as elsewhere, but on the other hand, mightn't fall as much either.
take out all the costs and see what the net is.
estimate your maintenance, empty periods etc,
also get the management charge and charge history to gauge how much it's going up.
I presume it doesn't have capital allowances.
what's your net yield after above charges,
what's your mortgage rate?
I think this should make the choice easier,
you might find for the effort of renting a property and all that entails, you're actually just covering interest, but could see it as guaranteeing yourself an apt at todays prices for the term.
add into your mix of other investment assets, and your tolerance for risk, here it's interest rate mainly.(use karls calc and add 1.5/2%)
and make your mind up.
