It is slightly different when purchasing a resale property, as this is normally ready to move into. The most important thing to note is that it is not the same as purchasing in the UK. In certain circumstances it has been known to complete in 15 days! Very rarely does it take any longer than 6 -8 weeks.
It is important when buying a resale property to ensure all finances (whether it is a cash purchase or an arranged mortgage) are in place before the final signing at the Notaria.
Many resale properties are sold partly or fully furnished and although the furnishings may not be to your taste it can help enormously when you first occupy the property.
