Well, if someone is looking to make some quick money, then it sounds like they should consider the coast, 100% profit in one-year sounds great!! Does that happen every year?
For example if you are looking to buy a house now on the coast does it mean you will have to pay twice as much as 12 months ago? Wow that’s got to hurt, paying double the price for a house you could have bought last year for half.
Maybe its better to buy in a stable market where there is a steady and consistent rise in prices rather than in an area where the prices fluctuate to double their value in 12 months, could they depreciate as fast?
Personally, apart from the property inland being better value for money, cheaper and also in demand, therefore quick resales for correctly priced property. I just feel the coast is too overdeveloped, as you mention golf courses, malls, developments springing up everywhere, how long before that nice little villa you bought becomes hemmed in and over looked by mass development? Wont be such a nice place to live if that happens, also how will all this over development affect the property prices, especially in an area where the prices are so turbulent, who knows what will happen, someone could double their money or equally loose it!
The trouble with these touristy areas are that in the winter they tend to close down and be a bit of a ghost town, who wants to live there when its winter, much nicer to be in a real town or village where people actually live all year round, easier to make friends and settle in to the community and there are things going on all year round,
Our nearest City is Tomar, a fantastic place with a wealth of history, its a unesco world heritage site, we have several top rated restaurants, that even compete with Lisbon, university, art galleries, museums, theatre, cinema, castles, top class shopping, as well as being surrounded by some of the most beautiful scenery in Portugal, lakes, rivers, mountains, forests, etc, as well as a plethora of historic Towns and villages, its one hours drive to Lisbon Airport, 10 minute to Castelo do Bode Lake, 40 miles of fresh water, great for water sports, Diving, swimming etc, easy road and rail links to the whole country.
I feel that although some consider us to be in the "sticks" having visited most places along the coast I think I can safely say we have a lot more to see and do here. Around here the locals consider the coast to be the edge of civilisation.
