To the comments about developers, etc. Remember, a bird in the hand is worth 2 in the bush.
As the Chinese saying goes,
If you use a person, do not doubt.
If you doubt a person, do not use.
In this case, if you are in doubt with the developer, do not approach with a stick of any length. Go around, ask and talk to folks not directly related to the property you are keen on, go to forums and after that, make up your own mind. Most importantly, it must be something you want.
Once you made up your mind, check again, like i posted before, property which has been built already are amongst the safest bet though prices will of course be higher.
Gelang Patah area, if you can, avoid it. I never had to go through it or pass through on my many trips. There are many many other areas with good food and safe too.
