My brother owns a vacation home in Spain.
I cannot say anything about the 3,000 euro requirement, as he and I are Belgians, and we fly or drive across the border with hardly a check (most of the time, when driving, you do not even have to stop).
Having said that, my brother has the house in what used to be a nice small village at the coast. He used to have all amenities, but now all streetlights are out, he regularly has no electricity, etc... He also says the prices for food, etc... skyrocketed, and the price of his house went into free fall. Also a lot of the restaurants, and shops, which made the place attractive had to close their doors.
Luckily enough he can wait till prices go up again.
Relocation to Spain, atm? Not a very good idea, unless you are loaded, can make some cheap real estate investments, and have the dough to live and pay for high food prices.
