Frequently Asked Questions (FAQ)

What Is Property Decoupling?

Property decoupling means removing one co-owner's name from the title deed, typically between spouses, so the outgoing owner can buy another property as a 'first-time' buyer.[1][2]

In Singapore, this shifts from joint tenancy or tenancy-in-common to sole ownership. The buyer (remaining owner) purchases the share at market value, triggering stamp duties and loan reassessment.[1]

Homejourney emphasizes: Decoupling must be genuine, not solely for tax avoidance, as ruled by the High Court.[6] Always consult professionals via our verified partners.

Joint Tenancy vs Tenancy-in-Common

Joint tenancy means equal shares with right of survivorship; decoupling converts to tenancy-in-common first for share transfer.[1]

Tenancy-in-common allows unequal shares (e.g., 99-1 split), common in decoupling to minimize duties, but IRAS scrutinizes artificial arrangements.[3]

Why Decouple? ABSD and Ownership Benefits

Primary reason: Avoid 20% ABSD on second properties for Singapore Citizens (SCs) in 2026.[1][5] Post-decoupling, the outgoing spouse qualifies for 0% ABSD on their first new buy.[1]

Other benefits include investment flexibility, estate planning, and better financing if one spouse has stronger credit.[4]

Buyer Profile	ABSD Rate 2026 (SC)
First Property	0%
Second Property	20%
Third+	30%

Example: $1.5M second property saves $300,000 ABSD post-decoupling.[1] But weigh against decoupling costs.

Eligibility Rules for HDB vs Private Properties

Eligibility hinges on marital status, property type, and compliance.[1]

Spouses: Legally married, both on title.[1]
MOP: Met Minimum Occupation Period (HDB: 5 years; private: check SSD).[4]
HDB Restrictions: Limited to marriage/divorce/hardship; no pure investment.[4]
Private Properties: More flexible via SLA transfer.[1]

Remaining owner must service loan alone and meet TDSR/MSR.[2] Use Homejourney's mortgage calculator to check.

Decoupling Mortgage Implications Explained

Decoupling triggers remove co-owner mortgage reassessment: The remaining owner assumes full loan, impacting TDSR (60% debt-to-income) and MSR (30% for HDB).[2]

Banks like DBS, OCBC, UOB review sole borrower's income, age, and credit. Expect potential rate changes or tenure shortening.

The chart below shows recent interest rate trends in Singapore:

With SORA at ~3% in 2026, refinancing costs rise if rates climb. Outgoing owner loses mortgage but gains buying power.[2]

Example: $800k loan, joint income $15k/month. Post-decoupling, sole owner ($10k income) may face higher payments or rejection.

Key Mortgage Changes

Refinancing: New loan application; compare DBS (1.8% fixed), OCBC SORA.Bank Rates
TDSR Impact: Full loan counts against one borrower's ratio.
