Also a word to the wise im sure as your older and wisr be careful trusting those courses many of us have done on body language and understanding the customer. Some trainers I have who have trained in phil and india have mentioned some of the major differences in those countries.
But from personally experience region to region person to person in phill I have notice small little difference that contradict the other local body language. Some even speak a different language or dialect and may use that body language!!!
Even wise locals get taken in as you say the stakes are high if it means the survival of your family.
Also regarding land take some time in the wifes family and circle of friends nearly everyone seems o have or know someone with land to sell.
Just today in the house we are staying in the Tita and Tito have suddenly realized how much land they had out the back as the workers clear the undergrowth to start up a new farm!!! It goes back for what seems like miles you could build a shopping mall init almost
Land in Phill gets over grown quickly and many may no realize if a family plot held for generations how much they have..
