Setting Your Maximum Price Before You Offer or Bid

The first price you see for a property, whether it is the asking price, a price guide, a neighbour's recent sale or an earlier offer, can quietly become the number every other price gets measured against. A maximum price set from recent sales of similar properties and your own numbers, written down before you are in a bidding room or on the phone, gives you something steadier to check it against. This guide covers what pushes a price upward, and how to set and write down your own maximum before you offer or bid.

What anchors your price

An asking price, a price guide, a neighbour's sale or an earlier offer, yours or someone else's, can all become an anchor: a number your mind uses as a reference point for every price it sees afterwards, even when the anchor itself was never tested. None of these numbers are necessarily wrong. The problem is treating one as evidence without checking what it is actually based on.

A price guide is not always a neutral estimate. In Victoria, for example, an agent's estimate has to be reasonable and based on research into comparable properties, and the agent should have knowledge of the local market to support it. Rules differ by state, so check what your own state's fair trading or consumer affairs office requires, and ask the agent directly which recent sales of similar properties the guide is drawn from.

A neighbour's sale can anchor you too, especially if it is recent and the properties look similar from the street. So can an earlier offer, one you made and had rejected, or one you have heard another buyer made. Neither tells you much about this property unless you can see how closely it actually compares: land size, building condition, strata scheme, exact location and how long ago the sale happened all affect whether a comparison holds.

The way to test any of these anchors is the same: list the sales you are treating as comparable, and note how each one differs from the property in front of you.

• Which recent, settled sales are genuinely comparable in land, building, condition, strata and location?
• How long ago did each recent sale of a similar property happen, and has the market moved since?
• Is the price guide or asking price backed by an explanation of what it is based on?
• Is the rent you are using confirmed, advertised, appraised or your own estimate?
• Which costs or repairs are still unknown rather than estimated?
• Are you anchoring on a number you or another buyer offered earlier, rather than on the property itself?

The pressures that push a price up

Beyond the anchor itself, a handful of common pressures can push a price higher than the number you started with.

• Auction atmosphere: bidding against other people in the room, with a countdown and public bids, changes how a number feels compared with reading it on a page.
• Fear of missing out: the sense that a property will not come around again, especially after a shortlist that has moved slowly.
• Sunk cost after inspections and reports: once you have paid for a building report, a strata report or a pest inspection, the money already spent can make walking away feel like a bigger loss than it is.
• Falling for the property: a property that matches much of what you pictured can make its price feel more justified than a strict comparison against recent sales would support.
• Competing buyers: knowing, or suspecting, that another buyer wants the same property changes the pace of a decision, even before a bid is placed.

None of these pressures is unusual, and none makes a decision wrong on its own. A maximum set in advance, before any of them are in the room, is more useful than a number worked out under them.

Setting your walk-away number

A maximum price, sometimes called a walk-away number, is what you decide in advance not to go past. There are three separate things worth checking it against before you settle on one.

From recent sales of similar properties: start with the sales you gathered while testing the anchor above. A maximum grounded in what genuinely comparable properties sold for is a different thing from a maximum grounded in what a property happens to be listed for.

From your own numbers: a property's price also changes what it needs to do in cash flow terms, at your own assumptions for rent, running costs and how you would fund the purchase. The example below works through this arithmetic at three different prices on the same rent.

From your budget and the cash you have ready: your maximum also has to sit inside what you can fund, including the cash you have ready for a deposit and upfront costs, and what a lender has indicated it will lend, which is an indication rather than a fixed figure until you are further along. Confirm your borrowing with your lender before you rely on it.

Example: how price changes the numbers

Example: a $650,000 unit renting for $600 a week, worked through at three prices to show how a higher price changes the numbers on the same rent. See how to calculate rental yield for the gross yield formula.

The rent stays fixed at $600 a week, or $31,200 a year. The example assumes a 20% deposit, an interest-only loan at 6.5% a year to keep the arithmetic simple, and running costs of $210 a week covering strata fees, council rates and water, landlord insurance, and property management and maintenance. It leaves out lenders mortgage insurance, assuming a 20% deposit, and leaves out stamp duty and other upfront costs, which do not change these weekly figures.

On the same rent, a higher price lowers gross yield and pushes weekly cash flow further negative, because the loan needed to fund the extra price grows even though the rent does not. This is an illustrative example: the interest rate, deposit and running costs are assumptions chosen to keep the arithmetic clear, not typical figures for any property or loan.

Write your maximum down

Once you have set a maximum from recent sales of similar properties, your own numbers and your budget, write it down before you are in a room, on the phone or in front of a countdown clock. A number that exists only in your head is easier to move in the moment than one that is already written.

It also helps to decide in advance what would actually change that number: new sales of similar properties, a revised rent appraisal, a building or pest report that changes what the property needs, or a change to your own budget. Deciding this ahead of time keeps a change of mind grounded in a reason, rather than in the room.

Auction or private treaty

The conditions attached to an offer differ depending on how a property is sold. In a private treaty sale, an offer can usually be made subject to conditions such as finance approval or a building and pest inspection, and in most states and territories a cooling-off period applies once a contract is signed, during which you can withdraw and get most of your deposit back.

At auction, none of this applies. A successful bid is generally unconditional and final the moment the hammer falls, with no cooling-off period and no opportunity to make the purchase subject to finance or an inspection. Cooling-off periods vary by state and territory in length and exceptions, so check your own state or territory's fair trading or consumer affairs office before you rely on one.

Setting your maximum in Virtual Buyers Agent

You can record the most you will pay once in your Investor Profile, along with the cash you have ready and a weekly out-of-pocket limit. Each property you track is compared against them, so you can see where a property sits against your own number rather than reconstructing it from memory each time.

Each property's Offer area keeps your working offer as it moves, separate from the price and rent evidence you record in Finances. The yield and cash flow figures Finances works out from your numbers are modelled figures, not a valuation or a recommended offer.
