30–90 Day IPA: MAS and Register Today’s Steps to Close in Singapore
An in-principle approval (IPA) is a bank’s non-binding estimate of how much it will lend you towards a property in Singapore, based on your income, debts, and credit record. It gives you a realistic budget before you start viewing units, strengthens your position when negotiating with a seller, and speeds up final approval once you’ve found a property. It is not a guaranteed loan; the bank confirms the actual figure only after underwriting and property valuation.
TL;DR:
- An in-principle approval limits your loan amount based on your income and credit, but remains subject to final underwriting and property valuation.
- The approval typically lasts 30 to 90 days and can be withdrawn if your financial situation changes, such as job loss or additional debt.
- Using an IPA early signals seriousness to sellers and helps you avoid paying costly options fees on unfinanced properties.
- Your loan amount depends on ratios like TDSR and MSR, with LTV limits and CPF considerations influencing your borrowing capacity.
- Applying with complete documentation and within your IPA’s validity date ensures smoother final approval and reduces delays.

Why get an in-principle approval before viewing or paying an option
An IPA sets your budget before emotions take over at a viewing. Sellers and agents in Singapore’s resale and new-launch markets take offers more seriously from buyers who can show a verified loan figure, and that credibility often translates into better terms during negotiation.
There’s a financial safety reason too. Paying an option fee on a property you can’t actually finance is one of the costliest mistakes a buyer can make, since option fees are typically non-refundable if the deal falls through on financing grounds. An IPA in hand removes most of that guesswork.
The main advantages:
- Budget clarity — you know your realistic borrowing range before shortlisting properties, not after.
- Negotiating leverage — a bank-verified figure makes your offer credible to sellers and their agents.
- Faster completion — much of the underwriting groundwork is already done, so the final Letter of Offer moves quicker once you’ve signed the Option to Purchase (OTP).
How banks assess your IPA: TDSR, MSR, LTV and credit checks
Your IPA amount isn’t just a multiple of your salary. The Monetary Authority of Singapore (MAS) sets the framework every bank must follow, and two ratios do most of the work in determining your loan quantum.
The Total Debt Servicing Ratio (TDSR) caps your total monthly debt repayments, including the new home loan, at 55% of gross monthly income. For HDB flats and executive condominiums, the Mortgage Servicing Ratio (MSR) further limits housing loan repayments to 30% of gross monthly income.
If you’re already servicing a car loan, personal loan, or credit card balances, that eats directly into the 55% TDSR ceiling and shrinks what’s left for a mortgage. Loan-to-value (LTV) limits also matter: how much of the property’s price a bank will lend depends on how many outstanding home loans you already have, with lower LTV caps applying from a second property onward.
CPF matters too. Banks typically factor in your CPF Ordinary Account balance and contribution history, since some buyers plan to use CPF funds towards monthly instalments. Variable income, commissions, and bonuses tend to get treated more conservatively, often averaged over recent years, which explains why two applicants earning the same headline salary can walk away with different IPA figures.
Documents, channels and timing: how to apply for an IPA in Singapore
Getting your paperwork right the first time is the single biggest lever over how fast your IPA comes through. Here’s the typical sequence:
- Gather your documents — NRIC or passport, recent payslips, CPF contribution history, latest Notice of Assessment (NOA), existing loan statements, and bank statements. If you’re declaring rental income, add your tenancy agreement.
- Choose your channel — apply directly through a bank’s online portal or branch, or go through a mortgage broker who can shop your profile across several banks at once, which is particularly useful if your income includes commissions or bonuses that banks assess differently.
- Submit and verify — many banks now let you use Singpass and MyInfo to pull your income and CPF records automatically, cutting down on manual document uploads.
- Wait for the outcome — turnaround ranges from minutes to a few working days depending on completeness.
Digital applications through MyInfo integration can be processed within minutes once every required document is in order, though incomplete submissions still cause the usual delays.
Pro Tip: Upload every requested document in one go rather than trickling them in. Banks often queue applications for review, and a missing payslip or an unclear bank statement can push you back to the end of that queue.
How long does an in-principle approval last, and why banks withdraw it?
Most banks issue an IPA valid for roughly 30 to 90 days, though the exact window varies by lender. Once it lapses, you’ll need to reapply, which usually means resubmitting updated documents rather than starting from scratch.
An IPA is a preview, not a promise. It’s built on your declared income and an initial credit check; the bank still needs to complete full underwriting and value the actual property before issuing a binding Letter of Offer. Several things can cause a bank to revise or withdraw an IPA before that point:
- Losing your job or a significant drop in income.
- Taking on a new car loan, personal loan, or other major debt.
- Undisclosed existing liabilities surfacing during the final credit check.
- Material changes to your credit record, including missed payments.
Because of this, treat your IPA validity date as a real deadline, not a formality, and align it with your property search timeline.
Using your IPA to make an offer: timing and precautions
Once you have an IPA in hand, use it deliberately rather than as a background reassurance. Share the figure and its validity date with your agent or the seller’s agent early in negotiations. A verified loan amount signals that you’re a serious buyer, not someone still working out whether the numbers add up.
A few practical guardrails:
- Never commit to a price beyond what your IPA supports, even if a seller pushes for more; the gap becomes your problem at final underwriting, not theirs.
- Time your Option to Purchase so the exercise period falls comfortably within your IPA’s validity window, since re-applying mid-negotiation adds stress and delay.
- If your search drags on past the IPA’s expiry, reapply before signing anything rather than assuming the original figure still stands.
Pro Tip: If you’re eyeing a property that’s likely to attract competing offers, ask your bank whether it can fast-track a refreshed IPA closer to your expected offer date. It keeps your figure current without forcing an early reapplication.
Common mistakes that invalidate an IPA or weaken final approval
Most IPA problems are self-inflicted and entirely avoidable. The pattern shows up again and again:
- Taking on new debt after approval — a car loan or credit card splurge between IPA and OTP can shift your TDSR enough to shrink or void the offer.
- Quitting or changing jobs mid-process — even a lateral move can trigger a fresh income review that delays or downgrades your approval.
- Submitting incomplete or inconsistent documents — an unmentioned existing loan discovered later damages both your loan quantum and the bank’s confidence in your application.
- Assuming IPA equals guaranteed approval — the final Letter of Offer depends on the property’s valuation matching the purchase price, which an IPA never confirms in advance.
Small, boring discipline between IPA and completion protects the number you were quoted.
Register Today’s perspective on using an IPA to win deals
We treat an IPA as the starting figure for every negotiation strategy, not a background formality. When a client’s IPA and target property line up cleanly, we push harder on price; when there’s a gap, we flag it before an option fee is at risk. One buyer we advised nearly committed to an option beyond their IPA ceiling until we recalculated the numbers against their confirmed track record of completed deals, saving them a forfeited deposit. Getting the sequencing right, IPA first, offer second, is what separates a smooth purchase from a costly one.

Our detailed market evaluations help you spot pricing gaps other buyers miss, and because we work across both resale and new-launch listings, we can match properties to your exact loan quantum rather than a generic price bracket. Browse our current property listings to see what fits your IPA today, or get in touch for a valuation before you make your next move.
