Well... there's several implications..
You'd need a BER, which you'll need anyway for selling.
You'll need to register with the PTSB..
There might be tax issues like CGT.. I am totally unsure but it'd need to be checked.
I feel you must pay the 200 Euro tax anyway, as no-one is living in the house.. but this issue isn't really addressed in the FAQ, (i.e the issue of several siblings inheriting a house and not living in it, is the 200 due?, is each sibling liable for their proportion of the 200?, if one subling lives in the house but only owns 25% what happens? etc etc)
You also need to find tenants, draw up agreements, and do the whole landlord thing which is harder than it sounds.
The housing market may take a long time to recover...
The executor is the one who chooses what must be done, .. if one sibling wants their share now then the executor should really be trying to sell..
Nothing is easy in these situations, and accurate info is hard to find.
Cheers
