And, hold on to the ladder, it will come in handy.
Back up for sale after a previous deal fell through is 4, Red Abbey Street in the heart of old Cork city's south parish.
It has a guide price of just €65,000, but the pictures here give a slender clue as to why it is so cheap.
The sale fills a narrow gap in the market place in terms of sheer affordibility, and the house itself fills a gap you'd hardly know existed between its neighbours.
No 4 clearly was hived off from the adjoining house to the right at some stage in the past: the entrance is through a narrow door squeezed in with one other door to the neighbours, sharing an old fanlight over the two.
From here, veer sharp left, but down't go too far: there's hardly 12' foot of space in any direction.
This entry level is your living room and kitchen, with stairs to a first floor bedroom and possibly euphemistically titled shower room, and there's another bedroom above this again.
To maximise what is a minimum of space, a new owner might be tempted to chuck out the stairs and use a ladder/fireman's pole, or at the least a spiral stairs.
Estate agent Nicola Murray of Frank V Murphy Ltd says the property needs total refurbishment.
At the price, it could be an enthusiastic DIY job and even prompt some innovative minimalist architectural notions.
Alternatively, some fledgling investor might see the income potential of two bedrooms and literally squeeze a few tenants in the door.
