Did another case, this time for a couple living in a condo. More "atas" with higher net worth. Yah yah papaya.

Professional couple living in $1.5m condo. Retired at 55.
CPF minimum sum = $296k (total for both)
Medisave minimum = $81k (total for both)
Net worth : $2.5m
Emergency fund : $80k

cash available for investment : ($2.5m - $1.5m - $296k - $81k - $80k) = $543k
$543k Invested in stocks (Reits) @ 7% returns : $38k pa

Yearly expenses: $80k
Shortfall : $42k pa.*

To make up the shortfall, chip into emergency fund - gone in 2 years.

Start to chip into invested fund : deplete in another 8 years.

Annuity life kicks in at 65. Expected Payout for couple : $36k pa.

Shortfall : $44k pa.

Downgrade from condo to HDB to free up more cash to last remaining years

Bottomline : at the end of the day, cannot hold on to condo, but still got more room to manoeuvre than HDB couple.
