first, choose the area you like
2nd, how much monthly income you have (bank loan installment normally is 1/3 of your salary, otherwise bank will not approve the loan)
3rd, own stay or investment, if investment, need to check how neighbor area perform in returns (rent & property price appreciate %)
      if own stay, for me, Q is near work place is better if you are now early 20s, near baby sitter house if you are in 30s, near ambiance , bird singing quite place if want to retire
4th, got facilities around, eg, bus stop, school, pasar, other amenities etc
5th, you got to hv 10% of the property price in your savings, bank loan normally is 90%, spare extra for legal fee, maintenance initial deposit, TNB, SYABAS deposit, minor renovation cost (setting the lights, fan, water heater, gas hook etc)

I guess that's my 2 sen worth advise ...
