Look at your options !
Great subdivision potential close to the waterfront at Clontarf Beach.
Convert the 2 Flats to a home or subdivide off a fabulous 490sq m corner block and cut your costs in half.
Demolish, subdivide and build 2 great new homes.
Build a brand new Duplex oh so close to the waterfront only 400 metres
Just leave as the existing 2 Flats and reap your rewards with the capital gains.
