Quick answer
A fall in value doesn't normally change your loan on its own. A private mortgage isn't a margin loan, and the Letter of Offer sets out what counts as a default. The real pressure is the exit: a refinance may be smaller, or a sale may net less, while capitalised interest keeps adding to the balance. Borrowing with a buffer and planning the exit early protects you.
Key points
- Read your Letter of Offer: it lists the events of default, and a market fall alone usually isn't one
- The exit is where a fall bites: smaller refinances and lower sale proceeds
- Capitalised interest grows the balance while the value may be shrinking
- Borrowing well under the maximum LVR is the simplest protection
- Open terms let you repay or pay down early, without penalty, if the market turns
Most owners take out a private mortgage with one eye on the business problem and the other on the property market. If prices soften while the loan is running, what happens? Does the lender ring up and demand money? Does the loan suddenly breach some limit?
For most secured business loans, a fall in value doesn’t change anything on the day it happens. The loan keeps running on the terms you signed. Where a softer market really hurts is at the end: when you go to refinance or sell to repay. This guide explains why, and what you can do about it while there’s still time.
What does the market look like right now?
It depends where you look. The Reserve Bank’s October 2026 Financial Stability Review said housing prices had declined in recent months as sentiment weakened. It also found most borrowers still have sizeable equity: fewer than 1 per cent are estimated to owe more than their property is worth, and even in a uniform 20 per cent fall, only around 5 per cent of mortgages would be in negative equity. For commercial property, the same review said fundamentals had continued to improve across most markets, although some segments remain weak.
The ABS’s March quarter 2026 figures, an earlier snapshot, showed the mean dwelling price rising $22,300 to $1,111,100 nationally, with Victoria the only state where it fell.
The lesson isn’t that prices are about to crash. It’s that national averages hide local movement, and a short-term loan needs to work even if your patch of the market softens for a while. A suburb, a building type or a regional town can move quite differently from the headline figure, in either direction, so judge your exit on what similar properties near yours have actually sold for recently.
Can a lender call in the loan because values fell?
Your loan documents answer this, so start with the Letter of Offer and the loan agreement. They list the events of default: the specific things that let a lender demand repayment early. In secured business lending, these are usually about what you do or don’t do, such as missing a payment, breaching a term, or not repaying at the end of a fixed term. A general fall in market value isn’t normally on the list.
That’s a key difference from a margin loan on shares, which is designed to be topped up when prices fall. A property-secured private loan is set at the start based on the value then, and isn’t re-marked every month. Our guide to the Letter of Offer shows where to find these terms. If you see a clause about reviews or material adverse changes, ask what it means in plain English before you sign.
Where does a fall in value actually bite?
At the exit. Every short-term loan is repaid by something: a refinance, a sale, a contract payment or a settlement. Two of those depend directly on property values.
| Exit | How a fall in value affects it |
|---|---|
| Refinance to a bank or other lender | The new lender lends against today’s lower value, so the refinance may be smaller than the private loan |
| Sale of the security property | Net proceeds are lower, leaving less after the loan is repaid |
| Sale of a different property | Same effect, on whichever property is being sold |
| Business income, a contract payment or a tax refund | Not directly affected by property values |
There’s a second squeeze if interest is capitalised. Capitalising interest means no repayments for the first 6 months, which is a huge help to cash flow, but the balance grows each month. If the value falls at the same time, the equity cushion shrinks from both ends. Our capitalised interest worked example shows how the balance builds.

Illustrative example
Illustrative only. The business, figures and LVRs are invented to show the method.
A Melbourne printing business borrows $600k on a private first mortgage over its factory, which is assessed at $1.2m at the start: an illustrative LVR of 50%. The plan is to refinance to a bank in 12 months once two years of clean financials are available.
| At the start | After 12 months, value down 10% | |
|---|---|---|
| Property value | $1.2m | $1.08m |
| Loan balance (with some interest capitalised) | $600k | about $640k |
| Illustrative LVR | 50% | about 59% |
| Bank lends up to an illustrative 65% | about $700k |
In this example, the bank refinance still covers the private loan comfortably, because the business started at 50% rather than borrowing to the maximum. If the owner had borrowed $840k at the start, the same 10% fall could have left the refinance short.
Do residential and commercial property behave differently?
They can, and it’s worth thinking about which one is carrying your loan. Residential property has a deep pool of buyers and plenty of recent sales to compare against, so its value tends to be easier to read and quicker to realise. Commercial and industrial property depends more on the tenant, the lease and the yield a buyer can expect. A vacancy or a lease about to expire can move value more than the wider market does.
That’s one reason our limits differ by property type: up to 80% of value against residential and up to 70% against commercial, with lower limits on large acreage. The lower ceiling on commercial property builds in room for those swings.
In practice, the owners who feel a softer market most are those with a single, specialised property and an exit that depends on selling it within a narrow window. If that describes you, it’s worth having a fallback: a second property that could be sold or offered as extra security, or a refinance option lined up early. Our page comparing residential and commercial security covers how each is assessed.
How can you protect your exit?
You can’t control the market, but you can control most of what sits around it.
- Borrow with a buffer. Borrowing well under the ceiling for your property type is the cheapest protection there is.
- Choose a near exit. The shorter the gap between borrowing and repaying, the less time for values to move. A refinance plan that starts on day one beats one that starts in month eleven. Our exit strategy guide covers how to build one.
- Use the open terms. There’s no minimum or maximum term and no penalty for repaying early. If a contract pays or a sale settles early, repay or reduce the loan straight away.
- Pay down if you can. Partial repayments reduce the balance and restore the cushion, especially while interest is being capitalised.
- Keep a second exit in mind. If the refinance looks tight, could another property be sold, or offered as extra security?
- Talk early. If the exit is wobbling, the time to raise it is months before the end, not the week before. Our guide on loan term extensions covers how those conversations work.
Planning around a softer market? See if you qualify
A shift in the property market is one of those things that’s easy to worry about and hard to predict. The owners who come through it well are the ones who borrowed sensibly and planned their way out before they needed to.

Give us honest answers about value, what’s owing and how you plan to repay, so the loan is right-sized from the start.
Frequently asked questions
Can a private lender call in my loan because property prices have fallen?
Your loan documents decide that, so read the events of default in your Letter of Offer. In secured business lending, a general fall in market value isn't usually a default by itself. Missing payments, breaching other terms or failing to repay at the end of an agreed term are the usual triggers.
Will I need to top up the security if values drop?
Not as a routine thing. A private mortgage isn't marked to market like a margin loan. But if you want to extend or increase the loan later, the lender will look at the property's value at that time, so a fall can affect what's available then.
How does a fall in value affect my exit?
If you plan to refinance, the new lender will lend against the lower value, so the refinance may not cover the whole private loan. If you plan to sell, the net proceeds will be smaller. Either way, the gap has to come from somewhere.
Does capitalised interest make a fall in value worse?
It can. With interest capitalised, the balance grows each month instead of being paid. If the property's value falls at the same time, the equity cushion shrinks from both ends. That's why short-term loans with capitalised interest work best with a clear, near exit.
What should I do if I'm worried about values falling?
Borrow less than the maximum if you can, plan your exit early, keep the lender informed, and use the open terms to repay or reduce the loan as soon as funds come in. Starting a refinance early, before the loan has run long, also gives you more options.
Are property prices actually falling in Australia?
It varies by market and over time. The RBA's October 2026 Financial Stability Review noted housing prices had declined in recent months, while ABS figures for the March quarter 2026 showed the mean dwelling price still rising nationally, with Victoria the only state where it fell. Local conditions matter more than the national average.
