What is a Negative Sale of HDB Flat and CPF Refund?

TL;DR / Summary:

– A negative sale means your flat didn’t sell for enough to pay back what you owe CPF.
– You don’t pay the shortfall in cash, but it still comes out of your CPF savings, provided the flat is sold at or above HDB’s valuation.
– Holding your flat longer increases accrued interest, raising your CPF refund and the risk of a negative sale.

Homeownership in Singapore is often viewed as a safe investment or a reliable way to grow wealth. But what happens when the value of the flat drops, and you face an HDB ‘negative sale’?

While the term may stir anxiety for most homeowners, a negative sale isn’t necessarily all doom and gloom. There are hidden benefits that could turn this seemingly unfortunate situation into an unexpected opportunity. Let’s explore why an HDB negative sale might not be the financial disaster it’s made out to be.

💡 Note: A negative sale can also happen with private properties, but this article focuses on a negative sale in an HDB transaction.

What Is a Negative Sale?

A negative sale, also known as a negative CPF sale, is a shortfall between your HDB flat’s sale proceeds and the CPF refund you owe (the principal amount used plus accrued interest), after your outstanding mortgage loan is cleared.

How Does a Negative Sale Happen?

Your sale proceeds have to cover two things in order: the outstanding mortgage first, then the CPF refund. A negative sale happens when there’s not enough left after the mortgage to satisfy the CPF refund in full, calculated as:

Selling Price – Outstanding Mortgage – CPF Refunds (Principal CPF + Accrued Interest) = Negative Sale

The example below shows how a negative sale is calculated with sample numbers:

HDB Flat Selling Price

$420,000

Outstanding Mortgage Loan

$250,000

Sale Proceeds Left After Paying Off Outstanding Mortgage Loan

$420,000 – $250,000 = $170,000

Total CPF Refund (Principal Amount + Accrued Interest)

$150,000 + $40,000 = $190,000

Negative Sale (Sale Proceeds Left – Total CPF Refund)

$170,000 – $190,000 = -$20,000

In the scenario above, the sale proceeds of $170,000 are not enough to cover the total CPF refund of $190,000, after paying off the $250,000 outstanding loan.

Hence, there is a negative sale of $20,000.

So What Happens to this $20,000 Shortfall Due to CPF?

If the sale proceeds (including the deposit) after clearing off your outstanding housing loan are not enough to make the required CPF refund, you do not need to top up the shortfall in cash, provided the property is sold at market value or higher.

In other words, the shortfall is waived as long as you have sold the property at market value.

Is the Negative Sale of $20,000 an Out-of-Pocket Loss?

In this scenario, the negative sale of $20,000 is NOT an out-of-pocket loss.

Bear in mind, in this scenario, while the total CPF refund is $190,000, the principal amount used (or your own CPF monies) is $150,000. The other $40,000 is the accrued interest accumulated over the years on the principal amount that has been withdrawn from your CPF Ordinary Account (OA) to finance your property.

So, while some accrued interest has instead become a realised interest loss after the sale, at least it’s not an out-of-pocket loss.

What Happens to the Deposit When There is a Negative Sale?

When there is a negative sale, all the cash monies that you have received as the Deposit (Option fee + Option Exercise fee) have to be refunded to your CPF account before the completion of the transaction. Remember to keep aside the cash you received and deposit it into your CPF account when HDB informs you to do so.

3 Ways to Avoid Making an HDB Negative Sale

1. Opt to Pay Your Mortgage Loan with Cash Instead of CPF

That way, when you sell your property in the future, there are fewer CPF refunds to be made, and you get more cash proceeds in the end.

2. Choose a Bank Loan with a Lower Interest Rate, If Possible

With a lower monthly repayment, your CPF usage will be reduced, and the CPF Refunds, upon selling your property, will also be lower.

3. Do Not Hold on to the Property for Too Long

Your CPF Refund is based on the Principal Amount used plus accrued interest. If you hold on to your property for too long, the accrued interest will accumulate every year, and by the time you sell your property, the CPF refund amount will be very high, leading to a negative sale.

Frequently Asked Questions

Can I still buy another flat if my current sale leaves me with a CPF shortfall?

Yes, but expect to lean more on cash for your next purchase. A negative sale means little to no CPF flows back to you, so you’ll likely need more cash for the down payment on your next home, since your CPF Ordinary Account balance has been reduced rather than topped up by your previous sale.

If my sale proceeds barely cover my CPF refund, who pays for agent fees, legal fees, and stamp duty?

You do, separately, in cash. Since sale proceeds get used up paying off your mortgage and then your CPF refund, there’s typically nothing left over to cover costs like your agent’s commission, legal conveyancing fees, or stamp duty, so budget for these upfront rather than assuming they’ll come out of your sale.

Does HDB or CPF Board notify me in advance if my sale is heading toward a negative outcome?

Not automatically; the responsibility falls on you to check beforehand. You can review your CPF Property Withdrawal Statement or use HDB’s or Ohmyhome’s sale proceeds calculator before listing your flat, so you know your numbers ahead of receiving any offers, rather than finding out only at the point of completion.
