Is it common in Spain for Bank Surveyor Valuations to be significantly lower than actual purchase price?

    Normally the purchase price and the valuation figure differ around 10%(at times the valuation being 10% higher than the actual price).

    You should be aware that the Spanish Inland Revenue (Hacienda) will make an assessment of the amount declared on the title deed and compare it to their own valuation of the property. If they notice a discrepancy of more than 20% between the price quoted on the title deed and their valuation the local Tax Office will fine the seller claiming the difference plus interest and imposing surcharges.
