Hua Hin is not seeing many sales at this time. In my Subdivision I was able to purchase far below the asking prices of other houses nearby. If you can talk to the owner I always ask: " what is the least you would take for this?" What ever they say: Thats your starting point to negotiate. When people tell you that no one takes owner finance, don't believe it. Many won't but some will. I don't call it "owner finance". I just ask them if I can give them so much now and pay the rest so much a month or year until I have paid them their price? A lot of the owners here are non-residents and own the properties free and clear. They can make deals if they want? The hard part is getting past the broker and talking to the owner which may be an estate heir living in another country? The last house I purchashed was at a terrific price and was in escrow numerous times but kept falling through due to a reletive of the owner who really didn't care and was killing the sales. I finally solved the problem by having an Attorney contact the owner and convey the terms I wanted which they agreed to. Normally I would never use an Attorney as they tend to be deal killers, but in this case it solved the problem.
Look at a lot of houses and make a lot of offers that you would be happy to pay if accepted. Just figure that you will have to make 20 offers before one is accepted and don't get discouraged when they say no. Just keep making good "for you" offers and when one is accepted it will be a great deal for you!
I do use my Attorney to do the contract and check title. Also be sure to do your physical inspections.
