Purchase a resales townhouse@cheras area during 2012 and that time, rental can cover 100% of my mortgage loan amount.

If you are talking about current purchase and rental, my guess is that it will be hardly reach 60% - 70% for properties with value more than 500k.
I will consider it's a blessing from heaven if the rental can cover 80% - 90% for my condo which will be vp-ed next year. I kind of regret my decision to purchase a high-end condominium unit plus in this kind of environment now.

Its much easier to match the rental to mortgage amount for cheaper properties like low cost apartment,flat, single terrace house etc which cost 400k and below.

Long gone for the time when the rental can match or even earn abit after deduct your mortgage.
