Just to share my personal experience.
I seriously considered getting an old unit coz those are very much bigger and spacious. very value for money compared to new developments. However
for old units, one will have to fork out to replace stuff like electrical wiring, water pipes (if they are really jialat), cabinets for all the rooms, toilets etc etc. and for these expenses,
one has to fork out a lot of CASH or if not take up a renovation loan. r
enovation loan is limited by a cap (eg 7 times your salary) and the interest rate is exhorbitant.
for a new unit, everything comes sui-sui and u only need to buy furniture.
those earlier expenses are essentially parked under a Housing Loan which also charges a much lower interest. In view of this, I went for the new unit instead as I have yet to find a printer good enough for printing tons of money.....
