Would highly recommend you find a good impartial real estate advisor, property in the Philippines is like a black art, and prices aren't always what they seem. Also if you bought in the newest subdivision, you could find yourself with a depreciating asset, and living in a neglected half built sub division 10 years later.
You do see very nice houses outside subdivisions, particularly in the country or by the sea. You do lose your supposed security that you have in the subdivision.
