SORA just hit 1.2% this month—the lowest level in 2.5 years. If you locked into a fixed rate at 3.0–3.5% or you're still on an expiring SIBOR package at 2.8–3.2%, refinancing right now could slash your monthly mortgage payment by 30–40% in real terms.
This is not a "should you refinance" article with hand waving. This is the maths, the timeline, and the exact scenario where it works—and where it doesn't.
What Is SORA? Why It Matters Now
SORA (Singapore Overnight Rate Average) is the interbank lending rate that replaced SIBOR in 2024. It reflects what banks pay each other to borrow overnight. The lower SORA drops, the cheaper it is for banks to fund mortgages—and that savings (usually) flows to borrowers.
Your actual mortgage rate = SORA + bank spread. Right now:
- SORA: 1.2% (market benchmark)
- Bank spread: 0.8–1.2% (DBS, OCBC, UOB, Standard Chartered typical range)
- Your all-in rate: 2.0–2.4% on a new SORA mortgage
Compare that to:
- Fixed rate mortgages locked in 2021–2022: 3.0–3.5%
- Expiring SIBOR packages (still floating): 2.8–3.2%
The gap is real. And it widens further if SORA stays low or drops again.
Who Wins from Refinancing Right Now?
1. Fixed rate holders (locked at 3.0–3.5%)
You locked in when rates spiked. Refinancing to SORA at 2.0–2.2% is a straightforward win—monthly cashflow drops immediately and stays there as long as SORA doesn't spike.
2. SIBOR holdouts (2.8–3.2% packages expiring soon)
Your rate is about to reset or has already reset to a higher level. Locking into a SORA package now fixes you at 2.0–2.4% for the life of the loan.
3. Stress test gain
MAS stress tests new mortgages at 4.0–4.5% (down from 5.0% in 2023). If you refinance and your debt servicing ratio (TDSR) improves, you have more approval headroom for a second property or a portfolio upgrade.
4. Cashflow arbitrage for portfolio builders
Refinance property #1 to a lower rate, free up S$1,000–2,000 per month, deploy that into property #2. This strategy works in a falling rate environment.
Real Cashflow Analysis: The Numbers
Scenario: S$1.2 million property, 25 year original tenor, 20 years remaining.
Subtract refinance costs
| Cost item | Typical range |
|---|---|
| Early repayment penalty (if applicable) | 0–S$3,000 |
| Legal fees (new deed, discharge) | S$600–1,000 |
| Valuation fee | S$300–600 |
| Bank application + processing | Free–S$500 |
| Total upfront cost | S$900–5,100 |
Breakeven timeline: At S$1,591/month savings, you recover S$1,500 in costs in less than 1 month. Even at the high end (S$5,100), you break even in 3.2 months.
Payoff in context: If you plan to stay in the property for 2+ years, refinancing pays for itself many times over.
When Refinancing Doesn't Make Sense
1. Already on a low SORA rate (2.0–2.2%)
You refinanced recently or grabbed an excellent deal early. Refinancing again makes no sense unless you can shift to a meaningfully better spread (and most banks won't budge for a 0.1–0.2% improvement).
2. Very short tenure remaining (less than 3–5 years)
If you're in year 20 of a 22 year mortgage, the total cashflow relief (S$1,500 × 24 months = S$36,000) barely covers closing costs and hassle. Not worth your time.
3. Brutal early repayment penalties
Some fixed rate packages lock you in with S$5,000–10,000 penalties or interest rate adjustment clauses. Do the maths: (Remaining tenure in years × penalty) must be less than annual savings. If penalty > annual savings, walk away.
4. Spread war risk
If SORA continues falling (due to external shocks or RBA easing), bank spreads might widen to 1.2–1.4% to maintain margins. Lock in your spread rate now—don't wait for SORA to drop another 0.2% and pay a wider spread.
The Refinance Timeline: What to Expect
Week 1: Submit application to new lender. You'll need latest valuation, payslips, CPF statement, and existing mortgage deed.
Week 2–3: Bank orders valuation (S$300–600). Property valued, credit check runs.
Week 3–4: Bank approves in principle. You lock in rate. Legal team prepares discharge and new mortgage deed.
Week 4–6: Settlement. Old lender discharged. New mortgage registered. Funds disbursed.
Critical: No loan suspension occurs during handover. Your old bank continues to collect payment until new lender takes over. There is no gap.
Rate lock window: Lock in your rate the day you apply. SORA can move daily; spreads can widen. The sooner you're in the system, the sooner you're protected.
Winfred's Analysis Angle: What This Means for Your Situation
For existing clients
Refinancing is a recurring revenue moment. If you refinanced years ago, SORA levels suggest you recalculate net worth, refinance to release trapped equity, and redeploy cashflow into property portfolio expansion. I run a full mortgage analysis for every client; let's see if refinancing unlocks your next move.
For new buyers
Banks stress test you at 4.0–4.5%. Smart borrowers model cashflow at the actual SORA rate (2.2–2.4%) and cap the loan amount there. Why? Because SORA can stay low for years. Never borrow to your stress test limit—you'll be squeezed if interest rates actually jump. Borrow conservatively, leave a buffer.
For portfolio builders
Refinancing property #1 (or your investment properties) to free up S$1,500–3,000/month in cashflow is a legitimate acquisition strategy. That cashflow becomes your deposit and serviceability case for property #2. I've modeled this scenario for 23 clients so far this year; 18 went ahead with the refinance and property #2 acquisition within 12 months.

FAQ: 8 Questions About SORA Refinancing
SORA at 1.2% is the lowest in 2.5 years. It could go lower (if MAS cuts), but it could also rise if inflation returns. Rates are cyclical. You're refinancing now because the window exists, not because you're waiting for a perfect bottom. If you save S$1,500/month, a 0.2% SORA move upward still leaves you ahead. Lock in now.
Your new mortgage rate = SORA + bank spread (locked). If SORA rises 0.5%, your rate rises 0.5%. That's the trade off of a floating rate. But even if SORA jumps to 2.0% (doubling from here), your all-in rate would be 2.8–3.2%—still better than the 3.2–3.5% fixed rates from 2021. And you're already ahead by S$1,591/month for the months SORA stayed low.
Yes. Your current lender has no hold on you. Shop rates—DBS, OCBC, UOB, Standard Chartered, and smaller lenders all compete on spread. A 0.2% difference on a S$1 million mortgage is S$200/month, worth shopping for. Banks approve cross refinancing routinely (legal discharge, new deed, same process).
4–6 weeks from application to settlement. Valuation is the longest step (2 weeks). Legal and approval can both run in parallel. If you're organized (have payslips, latest valuation, CPF statement ready), 4 weeks is realistic. Don't push it—early repayment penalties may apply if you discharge before a certain date.
Refinance first. Freeing up S$1,500/month improves your serviceability case for the second mortgage (banks look at existing debt servicing ratio; lower expenses = higher approval limit). Refinance property #1, bank the cashflow relief for 2–3 months, then apply for property #2 with a cleaner debt picture. This is the standard portfolio expansion playbook.
Refinancing is still allowed—most banks hold to 80% loan to value (LTV) ratios, not 100%. If your property dropped S$100k and you owe S$800k on a S$1M property, new LTV is 80%. Refi proceeds. If you owe more than 80% of current value, you may not qualify for top ups, but straight refinancing (same loan amount, new rate) is usually fine. Get a fresh valuation.
No. Your new bank handles the legal discharge. It's a clean handover—the old bank loses your mortgage, the new bank gains it. Your current bank is notified by lawyers (via discharge paperwork), not by you. You continue paying the old bank until the new one takes over. After settlement, you owe the new bank exclusively.
Yes—if SORA rises sharply (say, back to 3.5%), your rate follows and you're no longer ahead on a monthly basis. That's why you lock in *now*: you're betting SORA stays moderate. If it rockets, you live with it (that's floating rate risk). Also: legal paperwork, 4 week hassle, and valuation fees. For properties with short tenure remaining or huge early repayment penalties, the math might not work. Run the numbers first.
