I downsized 2 years ago, minimal possessions and currently live in a small studio room, 5th floor, small balcony with a view of a mountain and the cost is 5000 baht $158 usd inc rent and utilities a month.
All i own is a 135cc scooter, laptop and camera equipment, clothes and an electric fan and a few watches. My life could nearly fit in a suitcase or 2. All i need is a few more zero's in my bank account and everything is sweet.
