Should You Decouple? A Practical Guide for Married Couples in 2026

Decoupling — where one spouse buys out the other's share of a jointly-owned property so the second spouse can buy a new one without ABSD — is back in conversation. With ABSD at 20% for citizens on a second residential property, the math can be compelling. It's also where the most expensive mistakes happen.

When decoupling makes sense

• The first property is meaningfully cash-flow positive or has substantial unrealised capital gain
• Both spouses qualify on TDSR independently for their respective loans
• You have a clear 7-to-10-year plan for both properties

When it usually doesn't

• The transaction costs (BSD on the buyout, legal fees, stamp duty) eat 18 months of yield
• One spouse can't service a mortgage independently
• You're chasing a launch and treating decoupling as the funding mechanism

The cooling-measure landscape

The 2023 ABSD hike pushed decoupling from "tax planning" to "near-mandatory" for couples wanting two properties. But cooling measures can move again — and any tightening typically applies to transactions in flight, not just future ones. Don't sign anything assuming today's rules persist for the full timeline.

A useful sanity check

Run this test: if ABSD were abolished tomorrow, would you still want the second property at the price you're considering? If yes, decouple thoughtfully. If no, you're letting tax planning drive a property decision — which rarely ends well.
