Buying a Resale HDB in 2026? The Cash You Actually Need (Not Just the Downpayment)

The hidden cash question

Here is the trap: your HFE letter and CPF balance may say you can afford a resale HDB flat, while your bank account says otherwise. A housing loan and CPF can cover much of the purchase, but not every bill. The right question is not simply 'Can I buy a $700,000 flat?' It is 'How much spendable cash must I have, and exactly when?'

OTP: the first cash payment

Before an Option to Purchase (OTP), get a valid HDB Flat Eligibility (HFE) letter and check your loan position. The HDB-prescribed OTP requires an Option Fee of $1 to $1,000 when granted and an Option Exercise Fee when exercised; together they cannot exceed $5,000, and both are paid in cash. The option period is 21 calendar days. These payments form part of the agreed purchase price, not an additional fee on top of it. If you do not exercise the OTP, you generally forfeit the Option Fee.

Valuation and application fees

After the OTP is granted, buyers using CPF and/or a housing loan must request HDB's value of the flat. Budget for the Request for Value fee and resale application fee, plus any incidental registration or administrative charges. Confirm the latest amounts on the HDB portal when applying. These smaller payments matter because they fall due before completion, not after you have moved in.

Cash-over-valuation (COV)

Cash-over-valuation (COV) is the amount by which the agreed resale price exceeds HDB's assessed value. If you agree to pay $700,000 and the assessed value is $680,000, the $20,000 difference is COV. It must be funded in cash: CPF housing savings and the housing loan are generally assessed against the lower of price or value. Do not confuse the asking price with HDB's valuation. And do not assume you know COV before the Request for Value result arrives.

HDB loan versus bank loan

Your financing route changes the cash requirement. With an HDB loan, eligible CPF OA savings and grants can generally cover the downpayment, subject to actual eligibility, available funds and the approved loan. With a bank loan at 75% loan-to-value, at least 5% of the lower of purchase price or valuation must come from cash; the remaining downpayment can generally be met with CPF and/or cash, subject to rules. A lower approved LTV can raise the cash requirement. Check your bank's actual Letter of Offer, not an online maximum.

A $700,000 resale-flat cash example

Take a hypothetical $700,000 resale flat valued by HDB at $680,000. At 75% LTV, the illustrative maximum loan is $510,000. The amount not covered by that loan is $190,000: $170,000 downpayment against the $680,000 value, plus $20,000 COV. With a 75%-LTV bank loan, at least $34,000 (5% of $680,000) of the downpayment must be cash, on top of the $20,000 COV: at least $54,000 cash before transaction costs and any CPF shortfall. The OTP deposit is part of the purchase price and should be counted within—not added twice to—the cash needed. For an HDB loan, the $170,000 downpayment may be funded with eligible CPF/grants if sufficient; the $20,000 COV still requires cash. These are illustrative numbers, not loan or grant approvals.

BSD, ABSD and legal costs

Buyer’s Stamp Duty (BSD) and, where applicable, Additional Buyer’s Stamp Duty (ABSD) also belong in the budget. For a $700,000 residential purchase, BSD is $15,600 under the prevailing residential rates: $1,800 on the first $180,000, $3,600 on the next $180,000, and $10,200 on the next $340,000. BSD is assessed on the higher of purchase price or market value. Eligible CPF usage may help fund stamp duties and legal fees, but cash may be needed upfront or for any shortfall. Check ABSD based on citizenship, property ownership and any applicable remission; do not assume it is zero for every buyer.

Renovation is not an afterthought

Then come the costs that never appear in the headline listing: conveyancing and registration fees, inspection and repairs, renovation, furniture, appliances, movers, temporary accommodation and a realistic emergency buffer. Renovation costs vary widely with condition and scope; an arbitrary '$10,000 to $30,000 cash is enough' rule can be dangerously misleading when COV alone might exceed it. Ask for quotations and keep your emergency savings separate from the purchase budget.

Jerry’s five-pocket cash test

Here is Jerry's five-pocket cash test: (1) cash due before OTP exercise, (2) bank-loan mandatory cash, (3) COV and financing/CPF shortfall, (4) duties, legal and completion charges, and (5) renovation, moving and contingency. Put a date beside every pocket. The same dollar must never appear twice in your plan. If you are selling another property, check the actual timeline and CPF refund before counting proceeds as available cash.

Resale HDB cash FAQs

FAQ: Can CPF pay COV? No—budget COV in cash. Is the OTP deposit extra to the resale price? No—it is part of the agreed price. Can I buy with zero cash using an HDB loan? Not safely: OTP fees, COV if any, and other cash-only expenses remain. Is $30,000 always enough? No; the correct answer depends on valuation, financing, CPF, stamp duties, renovation and your own buffer. The best resale flat is not simply the one your loan allows; it is the one you can complete, move into and continue owning without exhausting your financial resilience.
