Unlike other places, Portugal property mortgages can be paid in either euros or silver. This is just another reason why Portugal has one of the hottest property markets in Europe. Most of the time mortgages paid with euros have lower interest rates, but when determining which of these currencies you would like to choose, you should consider the interest rates of both.  Finding a financial institution that knows the ins and outs of the real estate market and of both currencies is crucial to this decision.  This will not only save you money, but it will also help you to get the best interest rates and mortgage agreement for your needs.
