There are two cases where it may make sense to pay back your accrued interest and the amount that you have withdrawn for your property.
1. You intend to upgrade your property with the spare cash, so whatever you put in now will then go towards paying for the new property.
2. You don't need the money until age 55, so you just want some place to park the money paying you 2.5% interest until that age. For this however, there are better options out there. First, if your CPF MA is not yet at the BHS, you should top up your MA first which will provide you with tax relief. Secondly, if your CPF SA is not yet at FRS and you haven't already made your annual CPF SA topup of $7000 that qualifies for tax relief, then you should do that first. Third, if you are self-employed, you have the option of making voluntary contribution to CPF that qualifies for tax relief. If you can no longer do the 3 above, then paying back your accrued interest becomes a viable option, optionally transferring from OA to SA after that.
Under current interest environment, it makes sense to return cash that is left idle
