Net Salary pm (ignoring investment returns rental income as it is a % of yr investment returns): $7,250
Total Expenses pm: $2,010; 27.72% of net salary, great job    70%+ savings?! 
Accumulated Investment/Investable Assets: $170K (88% from EPF)
Note: Excludes car (unless U intend to be a taxi driver after retirement) & house (i ass-u-me it's yr home, thus no income from it)

In my humble opinion:
Excluding inflation, U should be financially free in 2 to 6 years time, depending on yr investment assets' returns.
Note: Since 88%+ of yr Investment / Investable Assets are in EPF, it depends on yr age now.
eg if U are 25yrs old now +15yrs = 40yrs old only, NOT enough to withdraw from EPF.
Possible solution:
Drain EPF A/C2 into yr pocket with yr mortgage (go refinance it with a Flexi-mortgage or fixed % mortgage) - assuming U've not touched EPF A/C2 for yr mortgage settlement

IF the house is a rental investment:
Accumulated Investment/Investable Assets: $370K (41% from EPF) (still excludes car)
Excluding inflation, U should be financially free now to 4 years time, depending on yr investment assets' returns.
Note: Since 41% of yr Investment / Investable Assets are in EPF, it depends on yr age now, as above

Whoa... 35 only? 
U the Sifu leh, can save 70%+/- of yr net income (excluding asset returns). I can only hit about 46%+/-, thus i need another 8 yrs +/- to be "free" and have great options 

BTW, it's not just about the millions we have/hold in assets, it's also our ability to keep/not spend crazily, that affects our personal economy.
Thus, a person with $4M, with yearly expenses of $500K, will destroy that accumulation easily within 10 years, EXCLUDING inflation

Bro, being frugal is good, just ensure yr physical and mental health + relationships are as strong as your financials too.
Just sharing an experience - a relationship that soured nuked my net worth when i was younger and dumber. I was "supposed to be" financially free in 2012 / 2013 before the nuke
