How Much Should I Bid on a House in NSW?

The Question Every NSW Buyer Asks

You've found a property on Domain or MyHome. The asking price is $395,000. You want to make an offer — but how much? Should you open at asking? Below asking? What if someone else bids higher?

Most buyers rely on gut feeling, the real estate agent's suggestion, or what a friend paid for a similar house three years ago. None of these are reliable. The agent works for the seller. Your gut doesn't have access to transaction data. And your friend's purchase may have been in a completely different market.

There is a better way: look at what buyers actually paid for comparable homes in the same area, and let that data set your opening offer, your escalation limit, and your walk-away price.

Why Asking Prices Are the Wrong Starting Point

Asking prices in NSW are strategic anchors set by sellers and their agents. In supply-constrained areas like Sydney, asking prices are frequently set below expected sale price to generate competitive bidding. In slower markets, they may be set above what a buyer would realistically pay.

Either way, the asking price tells you what the seller hopes for — not what the property is worth based on comparable closed transactions. The NSW Valuer General records what buyers actually paid at completion. That's the data that should inform your bid.

How to Set Your Opening Offer Using Transaction Data

A disciplined opening offer should be anchored to the lower quartile (25th percentile) of comparable closed sales in the area. This means finding properties that are:

• Within 1.5–3km of the subject property
• Sold within the last 18–24 months
• Similar in size, type, and bedroom count
• Adjusted for time trends (prices may have risen or fallen since they sold)

The opening offer should never exceed the asking price when the property is priced within or above the comparable sale range. If the asking price is below the 25th percentile of comps — a potential underpricing strategy — then the data suggests genuine value and the opening can be set at the lower bound of the comparable range.

What About Sealed Bids and Bidding Wars?

When an agent calls for "best and final offers," you need a second number: the maximum you'd submit in a sealed envelope. This should sit between the median (50th percentile) and upper quartile (75th percentile) of comparable sales — the range where the majority of transactions close.

Above this, you need a hard ceiling — the absolute maximum supported by the local transaction record. Going beyond it means paying more than the data justifies, which is how buyers end up in negative equity when the market corrects.

Three Numbers, One Strategy

Every property bid should have three pre-defined numbers before you pick up the phone:

1. Opening offer — anchored to comparable sales, never above asking (unless underpriced)
2. Best-and-final — your sealed bid ceiling, based on the upper-middle range of local transactions
3. Walk-away price — the hard ceiling above which the data says stop

Having these numbers before you enter negotiations eliminates emotional bidding. You compete with confidence because your limits are grounded in what 379,000+ NSW property transactions actually closed at — not what someone hopes you'll pay.
