I live in Lake Garden City Nick, but I'm renting so I can't give you any info regarding price for buying. All I can tell you is that it is a very nice community and we like it here. The people are very friendly but not overly intrusive. It is quiet, unless you are looking at the house for sale across the street from us (neighbors have dogs that bark and howl 24/7).

The quality of construction seems high, (and I am a former construction engineer and have built a few houses). The common areas are very well kept. We've never used the pool but walking by it always seems well utilized. Occasionally guys with brooms will sweep the street, I assume they work for the developer, so that may end once the estate is sold out. Ditto for the guards at the gate, who don't really guard anything, just smile and salute when you drive in.
What else. Utilities are fairly reliable, occasional outages of water and electricity but they've never lasted very long. There are a few falangs around but I haven't met many as I tend to keep to myself. The only down side is that the road leading into the development floods regularly in the rainy season. Never enough to close it completely, but it is annoying. It looks to me like the drains just need to be cleaned out, but that never seems to happen.
Feel free to PM me if you have any specific questions or need further info.
