Yes, there are plenty of "villas" around Phu My and Phu My Hung that would suite. About 3 years ago, my friends lived in one, 3 stories, many rooms for $1200/month. Lots of dogs,big and little, in the area. I'm back home in Canada now but will write a friend who still lives in Sky Gardens and have her recommend an agent. When we were teaching there 3 years ago, the average cost of tuition at one of these schools was around 12,000-15,000/year, often with discount for second child. "Playing outside" is a bit different in Vietnam than Aus. or Canada... there's more concrete, less green space, but around Phu My there are a few more green spaces and most people come out at night to play as it's quite hot during the day, although you do get used to it.
