Hi Julim,
Basically things will be easier if you can enlighten me whether or not you will be looking to sell your existing HDB flat. Kindly refer to the following for your property investment.
a) YES, Flat will be sold! : you do not have to worry about the minimum sum as once your flat had been sold, cpf board will automatically assume your existing property as the only property to be pledge as the 50% of whatever minimum sum then. You may also continue to utilise cpf for your monthly mortgage loan repayment as such. Therefore, you will not have to worry on the minimum sum regulation since your new property is the only existing property.
b) NO, Flat will not be sold! : in this case, you will have to set aside a minimum sum depending on the regulated amount by cpf board then before you can utilise your cpf for your new property, be it for downpayment, stamp duty, monthly instalment etc.
Minimum Sum regulation will be applicable to both husband and wife meaning to say
each of you have to set a minimum sum of $53k in you cpf account (oa & sa combined). if the total available cpf combining for both of you is $120k now then in that case after setting aside the $53k in your account, balance can then be utilised. the same will apply to your husband. but that will kinda interpreted to be only a couple of thousands available for both of you utilising for your 2nd property then.
***NOTE: You may utilise your cpf for payment of your property up to a MAX 95% of the Purchase Price + Stamp Duty in any case dependent of your qualification of cpf utilisation in the minimum sum regulation.***
Trust the above is clear, please do not hesitate to drop me a line @ 82818888 should you have any further clarifications pertaining loan & or cpf minimum sum matters.
Cheers!
