Need advice in retirement:

5 rm HDB in ulu ulu Jurong area fully paid
Japanese 1.6L car fully paid
A shophouse unit not fully paid (still U/C no passive income as yet)
Investments + Stocks + FD +CPF - worth at maturity = $170k+
Cash $100k

Annual savings $80k after tuition for kids, parents' allowance, loan repayment etc.

Don't plan to retire soon as hate doing nothing at home. But wife keep hinting she wish to stop working on hitting early 50s. Have 4 children, 2 JC, 2 Sec, no maid. Not huge spender, holidays a short distance (HK, TH). Parents with a list of health issues, medical quite ex. Work in an unusual company that "super promotes" people in 50s to high post - hope will happen to me.
