Rental yield is only useful in town or city properties where there is a rental market. Rural properties are a lot harder to judge by this method. Another method, (and one which should apply to all properties) is the replacement method.

SCS guides about €150 per sq. ft. rebuild cost which is probably a lot higher than the reality.

So, get the square footage of the property, multiply by about €100 per sq. ft. for a new unfurnished house, then add a figure for the site.

A semi-detached site outside Dublin is worth approx. €60K.

Maybe for good measure, throw in about 10-15% for the fact the the house is built so you don't need to go through the hassle of building yourself.

The site value is the hard bit though and is where you can take account of premium locations.
