How much is the property worth? Seeing as it's inherited from your mother you might be entitled to its full cash value tax free. You can then invest in something other than property as you seem to be totally invested in that, it would give you a few bob to enjoy as well which more people should do. Just a thought.
I might also add that just because it's adjacent to UCG and NUIG DON'T THINK FOR ONE MINUTE YOU WON'T HAVE THINGS TO BUY FOR IT. Letting to students, especially 1st years has a habit of causing the owners to buy lots of stuff to replace damaged goods, but is tax deductable. I've found over the years that students can cause untold damage to a house if proper checks aren't in place. Believe me.
