Your Property Will Lend You Money At Mortgage Rates. Your CPF Decides How Much.

Three-month compounded SORA is sitting near 1.12%, and the cheapest advertised fixed home-loan packages are printing from around 1.32% (PropertyNet). Against that, an unsecured personal loan at 6% looks like a different asset class — because it is. Which raises a question most owners never ask: if the cheapest money in the market is secured on residential property, and you already own residential property, can you borrow against it?

You can. MAS calls it a mortgage equity withdrawal loan — an MWL — and it is a properly regulated product with its own chapter in the residential property loan rules (MAS). What almost nobody prices correctly is the size. Three rules set the ceiling, and the first one deducts money you spent years ago and can never get back in cash.

First, who is disqualified before the arithmetic starts

An MWL is a loan secured against the value of a residential property you already own. MAS caps the tenure at 35 years, and notes that the mortgage servicing ratio does not apply to MWLs — for a reason worth reading twice: MWLs cannot be taken out on HDB flats, or on executive condominiums still within their minimum occupation period.

So this article is not about HDB owners. If your home is a flat, the equity in it is not borrowable at these rates, full stop. The market this applies to is private residential owners — and, per the same MAS page, individuals, sole proprietorships and shell companies get the retail treatment while other corporate borrowers do not.

Rule 1: CPF counts against the cap as though it were debt

Here is the rule as MAS writes it. For an individual, the MWL — together with the amount outstanding of any loan secured on the same residential property, and CPF monies used — must fall within the applicable loan-to-value limit.

Read the middle of that sentence slowly. The CPF you withdrew to buy the property, plus its accrued interest, is not a loan. Nobody charges you a monthly instalment on it. It does not appear on your credit bureau file. But for the purposes of this cap it sits alongside your mortgage and eats the ceiling.

Take an owner with a private condominium valued at S$1,800,000, an outstanding mortgage of S$620,000, and S$310,000 of CPF principal and accrued interest sunk into the purchase. No other property, no other housing loan.

Without the CPF deduction the same owner would be looking at S$730,000. The CPF line costs them S$310,000 of borrowing capacity — every dollar of it, one for one. The households most exposed to this are precisely the ones who did the "sensible" thing and paid down aggressively with CPF.

Rule 2: a second property nearly halves the ceiling

The LTV limits, which apply to MWL applications made on or after 6 July 2018, are not one number:

Same owner, same property, but now they also carry a mortgage on an investment unit. The ceiling drops to 45% of S$1,800,000 — S$810,000 — and the arithmetic goes:

S$810,000 − S$620,000 − S$310,000 = −S$120,000.

Not a smaller loan. No loan. The existing mortgage and CPF alone already sit above the cap, so there is nothing to withdraw.

This inverts the intuition badly. Property investors — the people with the most equity on paper, and the most obvious reason to want liquidity — are the ones the rule shuts out hardest. The trigger is an outstanding housing loan on another property, not ownership of it; an investment unit that has been fully repaid does not count against you.

Rule 3: the 50% line where TDSR stops applying

Total debt servicing ratio applies to MWL borrowers who are individuals. Except when it doesn't:

It does not apply if the MWL amount, together with any other outstanding loan secured on the same property, is 50% or less of that property's current market valuation.

MAS gives its own illustration: Mrs Wong wants an MWL of S$300,000 on a property worth S$2,000,000, with an existing S$150,000 loan on it. The two loans together are 22.5% of valuation, so her TDSR is never calculated.

Now put our owner through the same test — and notice what is missing from it.

The waiver measures loans only. CPF monies used are in the LTV test but not in the TDSR test. That asymmetry creates a threshold nobody advertises:

The last S$140,000 of borrowing capacity is the expensive part. Cross into it and the bank must assess the household at the 55% TDSR limit using the medium-term interest rate floor rather than the rate actually being paid. On a 20-year MWL of S$420,000, the stress instalment is S$2,545 a month against an actual instalment of S$2,105 — and the existing mortgage is stress-tested alongside it, at S$3,757. Combined, that is S$6,302 of assessed debt servicing, which needs roughly S$11,459 of monthly income to clear 55% before any car loan or credit line is counted.

Stop at S$280,000 and none of that assessment happens.

What the money is actually worth

The point of all this is that the rate on the far side is a mortgage rate, not a consumer rate. Taking the TDSR-free S$280,000:

Two things fall out of that table, and they point in opposite directions.

The monthly is transformative — S$1,403 against S$4,090 for the same S$280,000. That is the whole appeal, and for a household facing a genuine large expense it is not a small thing.

But look at the total interest column. Stretched over 20 years, the "cheap" loan costs S$56,780 — only S$6,813 less than the 6% personal loan, because tenure quietly claws back most of what the rate gave you. Shorten it to 15 years and the saving is real: S$42,013. The rate is a genuine advantage. The tenure is where it gets spent.

Where this goes wrong

Three failure modes, in rough order of how often they bite.

You have converted unsecured risk into a charge on your home. A personal loan that goes bad is a credit problem. An MWL that goes bad is a repossession problem. The lender holds a registered charge over the property that supports both the original mortgage and the withdrawn amount. That is exactly why the rate is what it is — and it is not a footnote.

The instalment follows you into every future application. The MWL is debt. It counts in your TDSR the next time you buy, refinance or extend anything. Owners who draw equity to fund a deposit on a second property routinely discover that the withdrawal itself has consumed the servicing headroom the new purchase needed.

The valuation you are borrowing against is today's. All three ceilings are computed off current market valuation. Borrow to the maximum at a market high and a subsequent revaluation can leave the total facility uncomfortably close to the limit at your next refinancing, which narrows your options exactly when you want them widest.

The honest summary: an MWL is the cheapest large loan available to a private property owner in Singapore in 2026, and its size is decided less by what your property is worth than by what you already put into it. Before speaking to a bank, do the subtraction yourself — valuation × 75%, minus outstanding loan, minus CPF principal and accrued interest. If that number is negative, no amount of shopping around changes it.
