The first two articles in this series covered pricing and marketing reach, getting a correctly priced listing in front of the right buyers. What happens once those buyers actually make offers is a different skill entirely. An offer is not just a number, it is a package of price, financing certainty, timeline and conditions, and evaluating that whole package, then negotiating it without giving away your own position, is where a seller negotiating alone is most exposed.

An offer is a package, not just a number

The instinct when comparing offers is to rank them by headline price. That instinct misses the real question, which is how likely each offer is to actually complete on the terms proposed. A buyer offering a higher price but proposing a rushed exercise period, a small deposit, or vague answers about financing is not obviously the better offer once you weigh in the chance the deal falls over partway through. Evaluating an offer properly means looking at price alongside financing evidence, the exercise period requested, the deposit size, and the completion timeline together, not price in isolation.

Checking financing before you commit, not after

The single most useful document a seller can ask to see before accepting an offer is an in principle approval letter from a bank, or the equivalent HDB Flat Eligibility letter for a buyer planning an HDB loan. These are issued after the lender has reviewed the buyer's income, existing debts and credit record, so they carry real weight, far more than a verbal assurance. Total Debt Servicing Ratio caps a buyer's total monthly debt repayments, including the new mortgage, at 55% of gross monthly income, tested against a stress rate floor of 4% regardless of the actual mortgage rate offered, and HDB or Executive Condominium purchases carry an additional Mortgage Servicing Ratio cap of 30%. These limits apply regardless of what a buyer states informally, which is exactly why the document matters more than the conversation.

None of this guarantees completion. A bank's in principle approval still depends on a satisfactory valuation of your specific property and a final underwriting review, so checking financing reduces risk, it does not remove it entirely. That said, a buyer who cannot or will not produce this document, or who is vague about existing loans or a need to add a joint borrower, is telling you something worth a further question before you take their offer off the table for another buyer.

Why negotiating through an agent changes the outcome

Negotiating your own sale directly with a buyer is genuinely difficult to do dispassionately, because your own reservation price, your timeline pressure and your emotional attachment to the property are all visible in the room, whether you intend to show them or not. A buyer who senses urgency or disappointment has more room to push for a lower price or softer terms. An agent negotiating on your behalf acts as a buffer, carrying your instructions without carrying your visible stake in the outcome, which is a structural advantage a seller negotiating personally cannot fully replicate no matter how disciplined they try to be.

Offer evaluation criteria and common pitfalls

A checklist to weigh each offer against, not a guarantee of any specific outcome. Every buyer and every transaction is different.

For the mechanics of the document itself, see the complete Option to Purchase guide. If you want the fuller playbook on checking a buyer's financing before you accept, read how sellers can vet a buyer's financing, and if you are on the other side of a rejected loan after exercise, this guide covers what happens next. Sellers weighing their own obligations once an offer is accepted should also read can a seller back out after accepting an offer, and the negotiation mechanics themselves are covered in how to negotiate a property price.

Frequently asked questions

What should I check before accepting an offer, beyond the price?

Ask for evidence of financing, an in principle approval letter from a bank or an HDB Flat Eligibility letter for an HDB loan, and check that the approved quantum actually covers the gap between the price and the buyer's stated cash. Also weigh the exercise period and deposit the buyer proposes, and whether their funding depends on selling another property first. A slightly lower offer from a well prepared, verified buyer is often the safer choice over a higher offer from one you have not checked.

Why would an agent negotiate differently than I would on my own?

An agent acts as a buffer between you and the buyer, which keeps your reservation price, your true timeline pressure and your motivation to sell from leaking into the conversation. Negotiating on your own home directly with a buyer makes it far harder to hide urgency or disappointment, both of which a buyer can use to push for a lower price or more favourable terms.

What happens if I accept a higher offer from a buyer whose financing looks weaker?

You are trading a higher headline price for a higher chance the deal does not complete on time or at all. If that buyer's loan is rejected after they exercise the Option to Purchase, you are generally back to remarketing the property, in a market that may have moved, having lost the time the exercise period and completion runway consumed. Evaluating offers on completion certainty, not price alone, is exactly the judgment call worth having help with.

What happens if a buyer defaults after exercising the OTP?

Once an Option to Purchase is exercised, a binding sale and purchase agreement exists. The general position is that a buyer who cannot complete risks forfeiting the deposit already paid, and the seller may need to remarket the property and could have a claim for any resulting shortfall, but the exact outcome always depends on the specific wording of that contract. This is a matter for your conveyancing lawyer to confirm against your own agreement, not a general assumption to rely on.

Does Seller's Stamp Duty apply to me if my buyer's financing falls through?

No, and this is a common point of confusion. Seller's Stamp Duty depends only on how long you personally held the property before your own sale completes, it has nothing to do with why a previous buyer's deal fell through. If a sale never completes because the buyer defaulted, no transfer of your property has occurred, so no SSD event has happened. SSD only becomes relevant again if you eventually do complete a sale while still inside your own holding period window.

Should I always accept a cash offer over a financed one?

Not automatically. A genuine cash buyer does remove bank financing risk entirely, which has real value if you need a firm completion date. But most buyers in the Singapore market are financed, and a financed buyer holding a solid, verified in principle approval is not meaningfully riskier than a cash buyer once that approval is checked. Be more cautious with a buyer who calls themselves cash but is actually relying on proceeds from selling another property that has not yet completed, since that carries its own timing risk.
