I know that this may be difficult to answer, but I'm wondering how it works paying for a build. Is it a lump sum upon signing contract and then payments made for specific work done at certain contractual intervals? I know that this is all relative to the building company, the budget etc. but I'm curious about ball park figures. stevefarang, DrAndy and Bettyboo are 3 people I'm curious about. My budget is around 3 million Baht. After initial signing for instance, do you pay like 20,000 at a time? And when? I truly don't know, so any insight would be helpful.
