Most first time buyers budget for one number: the downpayment. They save toward 25 percent of the purchase price, feel confident when that figure sits in the bank, and then get an unpleasant surprise when Buyer's Stamp Duty, legal fees and a handful of smaller charges land on top, all payable in a tight window after the Option to Purchase is exercised. None of this is hidden information, but it is scattered across different sources and rarely assembled into one cash stack. This guide puts every line item in one place, in the order it actually falls due.
What "cash to buy" actually includes
Before you view a single unit, it helps to separate the purchase price from the cash you personally need to produce. The purchase price is largely covered by your mortgage and your downpayment. The cash you need to produce is a narrower, more specific list: the option fee to secure the Option to Purchase, the cash portion of your downpayment, Buyer's Stamp Duty, legal conveyancing fees, a property valuation fee if you are borrowing from a bank, and mortgage stamp duty on the loan facility itself. Each of these has its own due date, and several of them fall due within days of each other once you exercise the option, which is exactly when buyers feel the squeeze.
The downpayment: cash versus CPF
For a bank loan, the standard Loan to Value limit on a first housing loan is 75 percent of the purchase price or valuation, whichever is lower. That leaves a 25 percent downpayment. Of that 25 percent, at least 5 percent must be paid in cash. The remaining 20 percent can come from cash, CPF Ordinary Account savings, or a mix of both. This is the single biggest lever in your cash planning: if your CPF Ordinary Account has enough balance, you can meaningfully reduce the cash you need to find, while still meeting the minimum 5 percent cash requirement that CPF cannot substitute for.
An HDB loan works on a different structure, with a higher Loan to Value ratio and different minimum cash rules, which is one reason the decision between an HDB loan and a bank loan is worth working through properly rather than defaulting to whichever your agent mentions first. I go through that trade off in my HDB BTO versus resale guide for first time buyers.
Buyer's Stamp Duty: the tiered scale
Buyer's Stamp Duty, or BSD, is a government duty calculated on a tiered percentage of the purchase price or market value, whichever is higher. The current residential BSD schedule applies 1 percent on the first $180,000, 2 percent on the next $180,000, 3 percent on the next $640,000, 4 percent on the next $500,000, 5 percent on the next $1,500,000, and 6 percent on any remaining amount above that. This is calculated once and is separate from any Additional Buyer's Stamp Duty you may also owe. BSD is due within 14 days of exercising the Option to Purchase, which means it needs to be sitting ready as cash or CPF at almost the same moment you are also settling the balance of your downpayment. For the complete mechanics including how BSD interacts with ABSD, see my complete Buyer's Stamp Duty guide, or run your own numbers on the stamp duty calculator.
The other costs people forget
Beyond the downpayment and BSD, a handful of smaller items round out the stack. Legal conveyancing fees cover your lawyer's work on the title search, requisitions, the Sale and Purchase Agreement or resale documentation, and completion. A property valuation fee applies if you are taking a bank loan, since the bank needs an independent valuation before disbursing funds. Mortgage stamp duty applies on the loan facility itself, calculated at 0.4 percent of the loan amount, capped at $500. None of these individually move the needle the way BSD or the downpayment does, but together they add a real sum that should not be an afterthought.
ABSD if this is not your first property
If you already own a property, Additional Buyer's Stamp Duty applies on top of BSD, and it is calculated on a separate schedule that varies by citizenship status and the number of properties you currently hold. For Singapore Citizens buying a second or subsequent property, PRs, and foreign buyers, the ABSD rates are meaningfully higher than BSD and need to be planned for as cash or CPF alongside everything else in this stack. If ABSD applies to your situation, it usually becomes the largest single line item in your cash plan, larger than the downpayment shortfall or BSD combined, so it deserves its own dedicated planning rather than being folded into a general estimate.
Worked example: how the stack scales at $1M, $1.5M and $2M
Rather than quoting a single dollar figure that will date quickly as rates and your own numbers change, it is more useful to understand how each component scales with price, then run your own numbers.
| Line item | How it scales with price |
|---|---|
| Minimum cash downpayment | Scales linearly at 5 percent of price for a bank loan. Doubling the price roughly doubles this line. |
| Buyer's Stamp Duty | Rises faster than linearly once you cross each tier threshold, because higher tiers carry higher marginal rates. A $2M purchase pays proportionally more BSD than a $1M purchase, not just double. |
| Legal fees | Move only modestly with price. This line is close to flat across the $1M to $2M range. |
| Valuation fee | Typically a fixed or lightly scaled fee, not materially different across this price range. |
| Mortgage stamp duty | 0.4 percent of the loan amount, capped at $500, so it grows with loan size until the cap is hit. |
Table shows how each component scales, not fixed dollar totals, since your loan quantum, CPF balance and citizenship status all change the actual figure. Use the BSD tiers above and the stamp duty calculator linked to compute your own numbers precisely.
The practical takeaway is this: as price rises, the two components that grow fastest are the cash downpayment and BSD, because both are directly tied to price and BSD accelerates through its tiers. Legal and valuation costs barely move. So when you are comparing what a $1.5M purchase costs you in cash versus a $1M purchase, do not simply scale everything by 1.5x. Compute BSD properly using the tiers, and compute your 5 percent cash minimum on the new price, then add the roughly flat costs on top.
How to build your cash stack before you start viewing
- Separate cash from CPF early. Know exactly how much of your downpayment can come from CPF Ordinary Account and how much must be liquid cash, since the 5 percent minimum cash rule on a bank loan cannot be substituted with CPF.
- Compute BSD, and ABSD if applicable, before you make an offer. These are due almost immediately after exercising the option, so they cannot be an afterthought funded later.
- Get a legal fee quote upfront. Ask your conveyancing lawyer for an estimate early so it is not a surprise item during a tight completion window.
- Unwind illiquid savings with a buffer. If part of your cash sits in fixed deposits, bonds or other instruments, start the unwind before you begin viewing, not after you find a unit you want to exercise on.
- Add a contingency. Renovation, moving costs and the first few months of a new mortgage all draw on the same pool of cash. Do not plan to the very last dollar of your cash to close figure.
Frequently asked questions
How much cash do I need upfront to buy property in Singapore?
You need enough cash to cover the option fee, the minimum cash component of your downpayment, Buyer's Stamp Duty, legal fees, a valuation fee and mortgage stamp duty. For a bank loan the minimum cash portion of the downpayment is 5 percent of the purchase price, with the rest of the 25 percent downpayment payable in cash or CPF. Buyer's Stamp Duty is calculated on a tiered scale and must be paid within 14 days of exercising the Option to Purchase, so it needs to be available as cash or CPF at that point, not spread out.
Can I use CPF for the entire downpayment?
Not for a bank loan. With a bank loan and Loan to Value of 75 percent, at least 5 percent of the purchase price must be paid in cash, with the remaining 20 percent payable in cash or CPF Ordinary Account funds. An HDB loan works differently, with a higher Loan to Value ratio and no separate minimum cash requirement on the downpayment itself, though other costs such as legal fees and stamp duties still typically require cash or CPF at specific points in the timeline.
Is Buyer's Stamp Duty paid separately from the downpayment?
Yes. Buyer's Stamp Duty is a separate government duty calculated on a tiered percentage of the purchase price or market value, whichever is higher, and it is due within 14 days of exercising the Option to Purchase. It is not part of the 25 percent downpayment to the seller. Many first time buyers underestimate their cash needs because they mentally budget only the downpayment and forget BSD falls due almost immediately after exercising.
What other costs besides downpayment and BSD should I budget for?
Legal conveyancing fees, a property valuation fee if you are taking a bank loan, mortgage stamp duty on the loan facility, and if you are buying an HDB resale flat, potentially an HDB resale application fee. If you are not a first time buyer, Additional Buyer's Stamp Duty applies on top of BSD and is a significantly larger sum that must also be planned for in cash or CPF.
Does the cash stack change much between a $1M and $2M property?
Yes, materially. Because Buyer's Stamp Duty is tiered and rises at higher price bands, and because the minimum cash downpayment scales directly with price, both the absolute dollar amount and to some extent the proportion of cash required increase as the purchase price rises. Legal and valuation fees move more modestly by comparison, so the downpayment and BSD are the two line items that matter most when comparing price points.
Not sure your cash stack adds up?
Between CPF timing, BSD tiers and possible ABSD exposure, the real cash to close figure is rarely what a quick downpayment estimate suggests. A Property Portfolio Analysis lays out your actual cash requirement before you make an offer.
