You win the auction. You sign straight away. The deposit is due on the spot, commonly about 10% (sometimes less if the vendor agreed that before the day). In NSW that contract is typically unconditional. There is no subject-to-finance escape hatch like many private-treaty deals.

If the cash for that deposit is sitting in an offset, here is the plain version: the auction deposit is real money that leaves your account that day. The offset is just where it was sitting. Paying from offset is not a special loan trick.

This page is about that cash path. It is not the deposit-bond product page. If a bond stand-in fits better, see deposit bonds for first home buyers.

What happens to the deposit

The deposit usually goes to a stakeholder (often the agency trust account, or the vendor's solicitor). It is held until settlement. At settlement it usually applies to the purchase price. You are not "losing" 10% on top of the price if the deal completes as planned.

If the deal falls over, return versus forfeiture depends on why. After an unconditional auction exchange, buyer default (including not getting finance in time) often puts that deposit at risk. That is the auction trap. It is not an offset rule.

Contracts vary. Confirm the deposit amount, payment method, and stakeholder details with your conveyancer before you bid.

Moving cash out of the offset

To pay with offset cash, you withdraw or transfer it. Once that chunk leaves the offset, it no longer offsets interest until or unless funds return. Confirm cut-offs and cleared-funds timing with your bank and conveyancer. Same-day hopes are a common miss.

A deposit bond is the light contrast: the certificate can stand in at exchange so your cash stays put until settlement, if the vendor accepts it. Offset cash is the opposite move. Real money leaves now. You avoid bond fees. You also give up that slice of offset benefit for a while.

Neither path invents the deposit. Neither replaces loan approval. If you still need a low-cash loan door, start at which door.

When it helps

  • You have clear savings in the offset equal to the deposit the contract requires.
  • You understand auction means ready cleared funds and an unconditional contract.
  • Stamp duty and the rest of settlement cash are planned with your conveyancer before you raise a hand.
  • You want cash on the day and would rather not use a bond.
  • You can live with less offset balance between auction and settlement.

That is the client. Cash is ready. Unconditional risk is understood.

When to leave it alone

Leave it if you have no funds plan for deposit day: transfer cut-offs, bank delays, or payment methods the contract will not take.

Leave it if you are treating auction like private treaty subject-to-finance. It usually is not.

Leave it if you assume the 10% always comes back if the bank says no after you have already exchanged. After unconditional exchange, buyer default often puts the deposit at risk.

Leave it if you are inventing a stamp duty number in your head. Plan costs with your conveyancer. Do not bid on a guess.

Leave it if paying the deposit drains buffers you still need for living costs or settlement.

Leave it if a deposit bond is the cleaner door because cash is better left offsetting, or settlement funds arrive later. See deposit bonds for first home buyers.

Folklore to ignore

  • "The deposit can stay in my offset until settlement." No. Cash deposit means money leaves to the stakeholder.
  • "If the bank says no after auction, I always get the 10% back." Not how unconditional auction risk usually works.
  • "Paying from offset is a special loan product." No. Offset is only where the cash was parked.

Before you book

Bring the auction date, the deposit clause, how much cleared cash sits in offset, and whether you are truly ready for an unconditional exchange. I will tell you whether paying from the offset is clean, whether a bond is safer, or whether you should not bid yet.
