go check under the star classifieds. usually that's a good indicator of pricing of houses in your area or through iproperty. but as i recall, subang jaya and usj area are still commanding a slightly low price. eg. i spotted ad requesting for approx rm350-380k for subang jaya house with sizes of 22x75 or 22x80.
my business associates just bought a 20x60 house in usj6 for rm260k!
so go figure! but having said all that, i'm interested in subang jaya area as it holds lotsa potential!
good luck!
