I guess you will be buying more land in Bohol in the near future
Have listened to a few expats over the years telling me how they know that the Philippines will experience a property bubble. After 25 years i am still waiting for their prediction's to become a reality! If you are lucky or clever enough to buy the right piece of land here the value can increase 10 times in a few years. At the worst the value may stay the same, which is not really a problem as you will probably have payed cash.
If/when you build your dream home and want to sell it, then the price might go below what you paid for the land and construction. Most people who have that sort of money tend to want their own design etc...
