What you are buying

No cash floor. The whole 25% downpayment can come from CPF OA. A bank loan on the same flat would need S$32,500 of it in cash that CPF cannot cover. Both are assessed on MSR and TDSR, and both cap at 75%.

The cash floor is the part that catches people. However large the OA balance, a bank loan needs part of the downpayment in cash.
