In Ireland, the person buying the property pays for a surveyor to conduct a survey and write a report on the condition of the property. This enables the buyer to get an independent opinion on the condition of the property so they can make an informed decision on whether or not to sign contracts and commit to the purchase.
In some other countries, the seller is required to provide a "buyer's pack" which includes an energy rating, valuation, and building survey. Hower in Ireland sellers are only legally required to provide a BER (Building Energy Rating) cert.
Although the valuation is for the bank's benefit, the buyer will often be required to pay for a valuation too.
