As a rough guide you should budget for around 10% of the purchase price to cover your costs, although I would say in most cases it will be lower than this.
Here are the fees payable when buying a property in Portugal. The costs will vary depending on the purhcases price, type of property and whether the property will be your primary or secondary residence in Portugal.
– Transfer tax – IMT (notary and land registration fees are not applicable when buying a property which is held off shore)
