Sell One, Buy Two Calculator
Thinking of selling your current home and buying two properties instead, one in each name to sidestep ABSD? This calculator works out the cash freed up by the sale, then checks whether the two of you can afford two separate purchases and which of you should buy which property.
Estimates only, based on prevailing IRAS stamp duty rates and MAS loan-to-value and TDSR rules. Reliefs, remissions, CPF accrued interest and your bank's actual assessment are not applied. Buying a second property in your sole name still attracts ABSD if you already own one. Speak to a Cashew advisor before acting.

How to Decouple a Private Property in Singapore: The Step-by-Step Process
Decoupling a private property in Singapore involves one co-owner transferring their share to the other, leaving a sole owner. The process covers confirming the remaining owner qualifies for the full loan under TDSR, obtaining a market valuation, engaging separate lawyers, restructuring the mortgage, paying Buyer's Stamp Duty on the transferred share, refunding any CPF used, and completing the transfer. Key costs include stamp duty, legal fees, refinancing fees, and potentially significant CPF accrued interest.

Decoupling Private Property in Singapore: What Still Works, and What Is Now Illegal (2026)
Decoupling, or a part sale of one co-owner's share to the other, remains legal in Singapore in 2026 and can help couples manage Additional Buyer's Stamp Duty when purchasing a second property. However, IRAS and the courts now draw a clear line between genuine transfers at market value and contrived arrangements like the 99-to-1 scheme, with enforcement including surcharges and criminal prosecution. Whether decoupling makes financial sense depends on your property equity, CPF accrued interest, the remaining owner's ability to qualify for the full mortgage under TDSR, and whether there is a genuine reason for the transfer beyond tax savings.

The ABSD shortcut that could cost you the property
Nominee arrangements designed to avoid Additional Buyer's Stamp Duty are treated as sham transactions by IRAS, meaning the avoided tax becomes payable with penalties. Worse, courts will not enforce ownership claims built on an illegal purpose, so the real buyer can lose the property entirely to the nominee. Legitimate alternatives like decoupling exist but carry their own stamp duty costs and should be fully priced before assuming they save money.

Understanding sell one, buy two
The sell-one-buy-two calculator models the popular Singapore strategy of selling a jointly owned home and using the proceeds to buy two separate properties (one in each spouse's name) so each purchase avoids second-property ABSD. It shows whether the numbers work before you commit.
What this calculator does
"Sell one, buy two" is a restructuring strategy for couples who jointly own a single property. They sell it, then each spouse buys a property under their sole name. Because each person is buying as a first-time owner, both purchases sidestep the Additional Buyer's Stamp Duty that a second property would normally attract, and the household ends up with two assets instead of one, often one to live in and one to rent out.
This calculator brings the whole plan together: the net sale proceeds, the cash and CPF available to split between two purchases, the loans each spouse can individually support, the stamp duty on each new home, and the total upfront cash required. It tells you whether the strategy is feasible and what each property's budget can be.
How the calculation works
The calculator runs several connected steps.
First, it computes your net sale proceeds, the selling price less the outstanding loan, any Seller's Stamp Duty, agent fees and CPF refunds (including accrued interest) that must be returned to your CPF accounts.
Next, it splits the available cash and CPF between the two new purchases and works out the maximum loan each spouse qualifies for individually, since each now borrows on a single income under the 55% TDSR limit and a 75% LTV cap.
Finally, it adds the Buyer's Stamp Duty on each property (with no ABSD if each is a genuine first purchase) and totals the upfront cash needed, flagging any shortfall against your proceeds.
A worked example
A couple sells a fully paid S$1.8 million property, netting about S$1.7 million after fees and CPF refunds. They split this into two downpayments. Each spouse, borrowing on their own income, qualifies for a loan supporting a roughly S$1.3 million purchase. Both buy as first-time owners, so each pays only BSD (around S$34,600 each) and no ABSD, versus the 20% ABSD one of them would face buying a second home jointly. The calculator confirms whether each spouse's income actually supports the intended loan, which is the make-or-break factor.
Sell one buy two versus decoupling
Both strategies aim to legitimately avoid second-property ABSD, but they suit different situations. Decoupling keeps your existing property and frees one spouse to buy one additional home. Sell one, buy two replaces a single property with two new ones, resetting both owners' counts but incurring selling costs and the need to find two new homes. This calculator helps you size the dual-property route so you can compare it against decoupling on a like-for-like basis.
Who should use it
Couples who jointly own one property and want to build a two-property portfolio are the core audience. Upgraders thinking about owning both a home and an investment property use it to test feasibility. Anyone comparing restructuring strategies uses it alongside the decoupling calculator to see which delivers more assets for the cash available.
Why modelling it first matters
The strategy only works if each spouse independently qualifies for their loan and the combined cash covers two sets of stamp duty and downpayments. Many couples discover that a single income cannot support the intended purchase, or that selling costs and CPF refunds leave less cash than expected. Running the full model first prevents committing to a sale before confirming both onward purchases are achievable.
Frequently asked questions
What does "sell one, buy two" mean in Singapore property?
It means a couple sells their jointly owned home and each spouse separately buys a property in their sole name, so both purchases count as first homes and avoid second-property ABSD.
Does sell one buy two avoid ABSD?
Yes, when each spouse genuinely buys as a sole, first-time owner. Each pays only Buyer's Stamp Duty, not ABSD. The strategy must be structured correctly to qualify.
Is it better than decoupling?
It depends. Sell one, buy two ends with two new properties but involves selling costs; decoupling retains the existing home and frees one buyer. Compare both with the calculators and professional advice.
Can each spouse afford a property on one income?
This is the critical test. Each spouse must qualify for their loan alone under TDSR. The calculator checks individual affordability before you proceed.
What costs reduce my sale proceeds?
Outstanding loan repayment, any Seller's Stamp Duty, agent commission, legal fees and the CPF principal plus accrued interest you must refund to your CPF account.
