Part share purchase calculator

By MoneyBees

Stamp duty and cash to buy a share of a home: BSD and ABSD on the share, the lower ABSD when you already own part of it, and the bank loan on the share.

Frequently asked questions

Do I pay stamp duty when buying a part share of a property?

Yes. Buyer's Stamp Duty applies to the share you buy, and ABSD too if your profile attracts it. IRAS charges both on the higher of the price you pay and the market value.

Does a part share count as a property for ABSD?

Yes. As long as you own any interest in a home, IRAS counts it as a property you own, whatever the size of the share.

Do I pay ABSD when I buy my co-owner's share?

It depends on what else you own. A citizen whose only home is this one pays no ABSD on buying more of it. A citizen who owns this and one other home pays 20% instead of 30%, and a PR whose only home is this one pays 5% instead of 30%.

What are the conditions for the ABSD remission on an additional share?

You must be buying more of a single home you already have an interest in, any other buyer in the same transfer must have a lower ABSD rate than you, and the home must not be partnership property or, from 9 May 2022, held on trust.

How much can a bank lend for a part share?

MAS's rules look at the price and valuation of the part share. With no other home loan, the limit is usually 75% of the lower of the two, with at least 5% in cash.

Can I buy part of an HDB flat?

HDB allows a part-share resale at an agreed price, but not between a married couple. Adding or removing owners without a sale is limited to immediate family, with at most 4 owners.

What does the person selling the share pay?

Seller's Stamp Duty if they sell within the holding period, and a refund of the CPF they used plus accrued interest to their own CPF account. The decoupling cost calculator works this out.
