NotesinSpanish.com director Ben Curtis said the most important thing for people to consider is how they will financially support themselves in the new country.
Many individuals believe they can survive on savings, but "changes in the exchange rate" have damaged these plans and have occasionally resulted in people being unable to move back to their homeland, he declared.
The expert advised individuals to consider the expense of issues such as accommodation and average rents, as well as any potential employment opportunities.
He said: "You really need to be sure that there is work available in the region you are moving to."
Spain has been affected by the global financial crisis so it is no longer a case of "being able to turn up and find work anywhere", Mr Curtis declared.
Men and women thinking of moving to this nation should have "financial assets, guaranteed employment or a sound business concept", journalist and author Anna Nicholas recently stated.
