Updated September 2026. This is an affordability and sequencing framework, not financial advice or a forecast of landed-home prices.
Start with eligibility and timing
HDB owners must satisfy the conditions that apply to their flat before acquiring a private residential property. HDB's current private-property guidance explains how the Minimum Occupation Period is determined and how the rules differ for households with Singapore Citizen and Singapore Permanent Resident owners.
Calculate usable equity, not the headline sale price
Estimate the HDB sale proceeds after the outstanding loan, CPF refund with accrued interest, legal and selling costs, tax liabilities and any other amounts due. Keep renovation, moving and emergency reserves separate from the purchase budget.
Model the complete landed-home cost
- Purchase price and current BSD or ABSD where applicable.
- Cash and CPF required at each transaction milestone.
- Mortgage payments under higher-rate scenarios.
- Building inspection, renovation or rebuilding and contingency.
- Property tax, insurance, utilities and recurring maintenance.
- Temporary accommodation if sale and purchase dates do not align.
IRAS publishes the current Buyer's Stamp Duty and Additional Buyer's Stamp Duty rules. Confirm the household's position before exercising an option.
Sequence the move deliberately
Compare selling first, buying first and synchronised completion. Each changes financing, ABSD exposure, cash flow, negotiating position and housing continuity. Obtain binding financing, conveyancing and tax advice for the exact household before committing. An upgrade is viable only when the home and the cash-flow plan still work without relying on future appreciation.
