not sure i understand your question fully.
however property in the central portugal region around Tomar and Abrantes is much better value for money than property on or near the coast. a better bigger house with more land can easilly be purchased for the same money as a less desirable house on the coast. the region also offers stunning scenery with mountains, lakes, rivers, forests, lovely towns and villages that are as yet unspoilt and not over developed.

investment opertunities are everywhere old farm houses and cottages to restore, which will dramatically increase in value, plots for newbuilds that are available with great views and good sizes at very good prices, as well as a great buy to let market for holliday homes, near the lake property prices do increase as this is a very saught after area for holliday homes for people from lisbon (less than 1 hour away) the holliday and long term rental market is very vibrant here. lots of oppertunities in a stunning area that is the real portugal.
