The address: 36 Sundale Close, Mountainview, Tallaght, Dublin 24.

The agent: Michael Kelly and Associates.

The property: three-bed mid-terrace house for €300,000.

The landscape: situated on a cul-de-sac between Tallaght and Citywest. Five minutes by car from Tallaght Hospital and The Square, according to the agent.

The features: modern 90sq m (968sq ft) house has a livingroom with mahogany surround fireplace and semi-solid oak flooring. The kitchen/diningroom has lots of cupboard space while the bedrooms have fitted wardrobes. South-facing rear garden with a patio and block-built shed.

How much for an investor? On a 90 per cent mortgage at a two-year discount tracker rate of 4.4 per cent APR, the repayment per month would be €1,690.20 over 20 years, and €1,482 over 25 years.

On an 85 per cent interest-only mortgage over seven years at 4.4 per cent APR, the monthly repayment would be €935.85 for the first seven years.

How much for an owner-occupier to buy? On a 92 per cent mortgage at a one-year discount tracker rate of 4.5 per cent, the monthly repayments over 20 years would be €1,686.36, over 25 years €1,471.08, over 30 years €1,330.32 and over 35 years €1,236.48.

Potential: it would fetch a rent of €1,200-€1,300 per month.

Verdict: there aren't many three-bed houses in Dublin for this price but, with interest rate rises, the repayments on the 90 per cent investment mortgage above exceed the rental return by around €182-€282 per month on a 25-year mortgage.

However, stamp duty of €15,000 and legal fees upon purchase, plus the costs of maintaining the house, should also be taken into account.
