My opinion of Mont Kiara is that if you are rich and want a nice environment plus international schools for your kids then go for it. Mont Kiaras primary selling points are the international schools.

The second category of Mont Kiara purchasers are the upper middle income group looking for 700-900k props. Most likely you can't send your kids to Mont Kiara international school. Most likely you can't eat in Publika and shop in BIG everyday. You will have to travel to find cheap economy rice, groceries and to send your kids to Sekolah Kebangsaan.

If you belong to the 2nd category then purchasing Mont Kiara props just for face is a really bad idea. In terms of investment Mont K is not good due to the factors mentioned above.

When purchasing a home if you are still pinching pennies the house should be an investment as well. Since in future you can sell/refinance your house for further investments etc.

If u compare with capital appreciation and landed prop, no doubt MK condo u can't compete it for now...... Condo in MK for investment will need to be very very selective..... Need to kno very well what's the targeted tenants...... 
However.... What about comparing MK landed vs Cheras landed?..... Say 5 or 10 yrs down the road which will hav a higher appreciation value?....
