Quick answer

Site deposit funding is a short-term private loan, secured on property a developer already owns, that pays the deposit needed to exchange contracts on a new site. It suits off-market opportunities and tight deadlines where a bank can't move in time. Smaller amounts are possible the same day, larger ones within 24–48 hours once documents are in, and the loan is repaid at or after settlement.

Key points

  • Secured on a home, investment or commercial property you already own
  • Pays the deposit so you can exchange before someone else does
  • $20k–$250k possible same day; up to $5m possible within 24–48 hours once documents are in
  • Often a second mortgage or caveat loan, leaving your existing bank loan untouched
  • Exit is the settlement funding for the site, a sale or a refinance

Good development sites rarely wait. An agent calls with an off-market block, a vendor wants to exchange before the weekend, or a competitor is circling. The developer who can sign and pay the deposit first usually wins.

The trouble is that the deposit is often trapped in equity elsewhere: in your home, a finished project or a commercial building. Site deposit funding releases it in time.

What is site deposit funding?

It is a short-term private business loan, secured on property you already own, used to pay the deposit on a development site so you can exchange contracts. The site itself isn’t the security, because until settlement you don’t own it. Instead, the lender takes a mortgage or caveat over an existing property, such as:

  • your home or another residential property
  • a completed townhouse or unit from a previous project
  • a commercial, retail or industrial building
  • land you already hold (considered case by case)

Amounts run from $20k to $5m, so the same facility can cover a modest deposit on a duplex block or a substantial one on a larger site.

How quickly can a deposit be funded?

Speed is the whole point, so here is what’s possible:

Amount Possible timing What makes it happen
$20k – $250k Same day Clear title, ID ready, existing loan statement to hand
Above $250k up to $5m Within 24–48 hours All documents in and signed promptly

Nothing waits on a valuer, because no formal valuation is required. The lender assesses your property itself. In practice, the delay is almost always paperwork: an unsigned document, a missing statement from the first lender, or a solicitor who isn’t available. Line those up before you call and the timeline shrinks.

If an exchange deadline is looming, start the enquiry now and gather documents while it’s being reviewed.

Which loan type suits a deposit?

Because deposits are short and urgent, the structure usually follows what is already registered on your property:

  • Property debt-free: a private first mortgage. Simple, and the longest terms are available.
  • Bank loan in place, and you want to keep it: a second mortgage behind the bank, which normally needs the bank’s consent.
  • Deadline too tight for consent: a caveat loan, which can often be put in place faster and later converted to a registered second mortgage if the timeline stretches. The caveat loans page explains how that works.

Not sure which applies? The 60-second loan type quiz narrows it down.

Illustrative example: an off-market block in a hurry

Illustrative: A Melbourne builder-developer is offered an off-market corner block suited to three townhouses. The vendor wants contracts exchanged within four days, with a $150k deposit, and settlement in 120 days. The developer’s cash is committed to a current build, but they own a commercial workshop worth around $900k with $300k owing to their bank.

  • Security: a second mortgage over the workshop, behind the bank (or a caveat if consent can’t be arranged in time)
  • Loan: $170k, covering the deposit and the loan’s own costs
  • Interest: capitalised, so nothing is payable monthly
  • Term: set to run comfortably past the 120-day settlement
  • Exit: repaid at settlement from the developer’s land purchase funding, or from the sale of a completed unit on their current project

The deposit is paid on time, the site is secured, and the bank loan on the workshop stays exactly as it was.

What else should you budget for between exchange and settlement?

A deposit loan solves the exchange. Settlement brings its own costs, and the exit plan needs to cover them:

  • Stamp duty. In NSW, Revenue NSW says transfer duty is paid by the purchaser and must be paid by the earliest of settlement or three months after signing the contract. The off-the-plan deferral is only for eligible buyers purchasing a principal place of residence, and it isn’t available for investment or commercial property, or where the buyer is a trust or company. Most development purchases won’t qualify, so plan for duty in full. Other states set their own timing.
  • GST on the purchase. The ATO lists potential residential land and new residential premises as sales where GST withholding at settlement may apply, and the vendor must give you written notice before settlement either way. Your conveyancer will handle the mechanics, but your settlement figure should account for it.
  • The balance of the price. Usually from a land or construction lender, a joint venture partner, or the sale of other property.

For a fuller view of how short-term loans are repaid, read the exit strategy guide. And if the site will need a DA before anything gets built, the pre-construction costs page covers funding that stage too.

What if the settlement funding falls through?

This is the question to answer before you sign, not after. Once contracts are exchanged, failing to complete can put the deposit at risk, so the deposit loan should never rely on a single, untested source of settlement money.

Sensible developers line up a fallback:

  • A second asset that could be sold if the land or construction lender says no.
  • A longer first mortgage term on the deposit loan, so there’s room to find another settlement lender without a deadline crushing you.
  • A larger private loan at settlement over the existing security plus the new site, considered case by case, if the numbers support it.

Talk this through with the specialist reviewing your enquiry. A clear primary exit and a credible backup make a deposit loan far easier to approve, and they protect the money you’ve just put on the table.

What does the lender need from you?

Keep it lean and accurate:

  • the address and title details of the property offered as security
  • the latest statement for any existing loan on it
  • the contract or heads of agreement for the site you’re buying
  • photo ID for each borrower and director
  • a short note on how you’ll settle the site and repay the loan

Credit history, an ATO debt or past defaults are considered case by case. What matters most is real equity in the security and a believable plan to repay.

Find out if your deposit can be funded

You can enquire without a credit check, and your details aren’t passed around a group of lenders. Our lending partner fundU, the direct lender behind this site, has a specialist read each enquiry and respond with a clear view.

Be precise about the property you’re offering, who owns it, every debt registered against it, and your settlement date. Accurate details at the start mean the answer you get first is the one that sticks, which is exactly what you need when a vendor is waiting. Check whether your site deposit qualifies before the opportunity moves on.

Frequently asked questions

Can I borrow the deposit for a development site?

Yes, if you own other property with enough equity to secure the loan and you have a clear plan to complete the purchase or repay. The loan is secured on that existing property, not on the site you're buying, because you won't own the site until settlement.

How fast can a site deposit loan be funded?

Smaller property-secured amounts, from $20k to $250k, are possible the same day, and funding is possible within 24–48 hours for up to $5m once documents are in. Having your ID, title details and existing loan statement ready makes the biggest difference.

Do I have to refinance my home loan to get the deposit?

Usually not. A second mortgage or caveat loan sits behind your existing lender, so your current loan stays in place. A second mortgage normally needs the first lender's consent, while a caveat loan can often be put in place faster and later converted to a registered second mortgage.

When is stamp duty due on a development site in NSW?

Revenue NSW says transfer duty is paid by the purchaser and is due by the earliest of settlement or three months after signing the contract. The off-the-plan deferral is limited to eligible owner-occupiers, and isn't available for investment or commercial property or for purchases by trusts or companies.

What if the site settlement is months away?

Then the loan term is set to run past settlement, with a buffer. Private first mortgages can run for 1 to 24 months, and interest can be capitalised so you aren't servicing the deposit loan while you organise settlement funds.
