To research properties here you have to get an address go to the city hall get the tax record which has the owners name on it then try to find the owner. My wife purchased the property her family was squatting on for 30 years. The owner was not paying the taxes and she convinced the city to auction the property which she won. It was a risk they took but it paid off for them as the property is now worth 20 times what they paid for it. They paid P600,000 and was recently offered P10,000,000 for it.
