fact:
-TS is just 28 year old - (assume he is senior rank employee earning 4-7k per month?)
-1st home buyer
-need parent help for the down payment (i assume monthly income cant sustain the installment of 900k house?)
-possible already have a car loan (always need traveling around)
-hometown at melaka, need go shah alam/N9 for work
-worry about making wrong decision + asking around his fren for opinion and also stranger forumer opinion (not confident/comfortable with this option)

my suggestion:
-why not try to get a 300k prima/rumahvip if entitle? dont waste the 1st home quota
-hunt subsales, since you have parent support for deposit, really alot of option for you in bukit jalil.
-get a more defensive property (easy to rent out, near public transport, easy access, population is ONG) so you got choice wait for a better price before let go too cheap
