The address: 78 Tyrconnell Road, Inchicore, Dublin 8.

The agent: Ascot Properties.

The property: six-bed terraced house for €800,000 - representing a cost of €4,102 per sq m (€381 per sq ft).

The property: 195sq m (2,100sq ft) house with seven original fireplaces and original doors. It has five double bedrooms and one small single. The agent says the two downstairs reception rooms are large and one of them has been in use as a bedroom. There is a shower room downstairs and a bathroom upstairs. To the rear there's a garden and a garage.There are two workshops outside with a toilet. The agent says the property is generally in good condition but could do with some refurbishment.

How much for an investor? With stamp duty at 9 per cent and 0.5 per cent legal fees, the acquisition cost comes to €876,840. On a 90 per cent mortgage at a tracker rate of 4.15 per cent over 20 years, the annual repayments would be €53,042 (€4,402 per month). If the annual rent is €26,000, taking into account one month's costs and one month's void, the shortfall would be €27,042 per annum (€2,252 per month).

On an interest-only mortgage the annual repayments would be €32,400 (€2,700 per month) which leaves an annual shortfall of €6,400 (€533 per month). This represents a yield of 3.3 per cent.

An investor would break even on a 44 per cent annuity mortgage at a tracker rate of 4.15 per cent over 20 years.

Potential: it has been let until recently for €2,000 per month. The agent says there's potential to increase that to around €2,600 per month if the rooms are let individually.

Verdict: close to the Luas, it's very lettable but, as the calculations show, there would be a serious shortfall on anything over a 60 per cent mortgage.
