Build the upfront budget first
Start with the purchase price and the loan amount you can actually obtain. Separate the cash and CPF you plan to apply to the price. Add Buyer’s Stamp Duty, any Additional Buyer’s Stamp Duty, legal and valuation costs, and your renovation and moving budget. Some costs may be due before reimbursement is available.
Check buyer-specific tax treatment
Residential BSD is assessed using the higher of consideration and market value. Additional duties depend on the buyer profile and transaction circumstances. Joint ownership, reliefs and remissions require their own assessment. Enter the amount confirmed for your situation rather than treating a generic calculator as a tax determination.
Compare a monthly budget and a stress scenario
Mortgage instalments are only part of ownership. Add maintenance fees or S&CC, insurance, repairs and property tax. Test a higher interest rate using the same principal and tenure. A benchmark such as SORA is not the full interest rate in a particular bank offer.
Use Annual Value for property tax
A sale price does not establish IRAS Annual Value. Obtain the relevant Annual Value and apply the correct occupancy treatment and current rules. The calculator accepts a separately checked annual tax estimate so it does not invent a tax bill from the purchase price.
