Gazumping and gazundering explained
Ever had a deal you were certain of, only for the rug to be yanked out from under you at the last second? Welcome to the wild ride of property transactions, where gazumping and gazundering aren’t villains from a soap opera, they’re real-life tactics that can mess with your plans, finances, and nerves. Let’s break down what they are, why they happen, and how to protect yourself—without turning every home purchase into a total horror story.
What Gazumping actually means (and why it feels personal)
Gazumping is basically when you think you’ve locked in a deal, only for the seller to accept someone else’s higher offer. It happens after you’ve put down a deposit or gone through a pile of paperwork, sometimes within days or even hours of agreeing on a price. The euphoric moment you believed the house was yours? Poof, it’s gone.
Why does it feel so brutal? Because it isn’t just about money. It’s about time, emotions, and the long hours spent coordinating surveys, mortgage checks, and legal jargon. You’re not just buying a building; you’re buying a future. When that future gets hijacked, frustration, anger, and a strong desire for accountability kick in.
The flip side: Gazundering and the psychology behind it

Gazundering is the mirror image. It’s when the buyer, not the seller, lowers their offer as the exchange date approaches. The thinking goes: “If I stall long enough, I’ll get a price drop.” In practice, it’s a nerve-wracking game of risk management, and it rarely ends well for either side.
What makes gazundering especially annoying is that it targets the most vulnerable moments: just before contracts are exchanged, when everyone’s rushed, anxious, and juggling mortgage approvals. It’s not just chutzpah—it’s a calculated move to push the other party to concede. And yes, it can backfire spectacularly if the seller digs in or the buyer’s lender backs out.
How common are these tricks? Let’s separate myth from reality
– Gazumping: It happens more often in competitive markets, hotter areas, or when the seller has multiple sends of interest lined up. In a seller’s market, you’ll hear more stories of “we had another offer overnight.”
– Gazundering: This tends to spike when buyers feel pressure to close quickly, or when the market is soft and prices are sliding. It’s also more likely when buyers have conditional offers tied to mortgage approvals.
No one wants to be “that person” who plays dirty, but the reality is that both sides sometimes get caught in systemic quirks: slow conveyancing, lender delays, and the emotional rollercoaster of house hunting. FYI, both tricks are not illegal in most places; they’re often just frustrating and unethical, not criminal.
How the process works in practice (step by step)

– Step 1: You find a place you love and put in an offer. You’re excited, you’re hopeful, you dream of coffee in the kitchen with a sunbeam on your new countertops.
– Step 2: The seller accepts your offer. You’ve got a moment of victory. Now it’s all about paperwork, surveys, and approvals.
– Step 3: Gazumping can happen if someone else makes a higher offer after you’ve agreed. The seller may be tempted to switch.
– Step 4: Gazundering can happen if the buyer waits until the last minute to lower their offer or renegotiate the price as contracts near exchange.
– Step 5: Exchanges and completion. If the deal survives both parties’ last-minute moves, you get the keys. If not, you’re back to square one, with potential costs to recover or redevelop.
The practical upshot: both gazumping and gazundering derail timelines, increase costs, and create reputational risk for everyone involved. And yes, you might end up paying for surveys, searches, and legal fees even if the deal collapses.
Protecting yourself: practical tactics and smart moves
– Get a standout offer package. Make your bid clean and transparent: a strong mortgage approval, a clear chain of title, and a well-timed conveyancer schedule. When you’re first in line, you’re less likely to get outbid.
– Lock in a competitive but realistic price. Don’t overpay in a fever of excitement, but don’t underbid to the point you’re a liability if you win. A realistic offer with a credible timescale buys you more leverage.
– Use a lock-in or reservation agreement where available. Some markets offer a formal agreement that sets a price and timeline, reducing the chance of a surprise switch. It’s not a silver bullet, but it helps.
– Don’t skip surveys or checks. Skipping due diligence is romantic in movies; in real life, it’s financial folly. Get the building survey done, check for hiccups, and understand repair costs.
– Choose a proactive conveyancer. The right pro can push for early title checks, speed up the search results, and chase the other side’s responses. Being fast and informed matters as much as being thorough.
– Consider a “no gazump” clause if your market supports it. Some jurisdictions or sellers will accept a clause that buffers you from last-minute higher offers. It’s not universal, but it can be worth asking about.
– Prepare for fallback costs. Even with the best plans, deals fall through. Have a small financial cushion for surveys, legal fees, and temporary housing if needed. It’s not glamorous, but it reduces stress.
Dealing with gazumping if it happens to you

– Don’t lash out. It’s tempting to vent, but you’ll only complicate things. Take a breath, then re-evaluate your options.
– Reassess your position. Can you match or exceed the new offer? Do you want to keep chasing this property, or pivot to something better?
– Communicate clearly with your conveyancer. They can help you understand the legal levers, deadlines, and any penalties in your contract.
– Learn from it. If you were outbid, ask yourself what you could do differently next time—maybe a shorter closing window, maybe a stronger mortgage pre-approval.
– Consider softer outcomes. Sometimes you can negotiate a faster completion date with your seller if you’re flexible on terms, which can be a psychological win even if you didn’t win the bid.
Gazundering: when buyers trap themselves too
– Don’t sleep on your own deadlines. If your lender’s appraisal is dragging, push for faster updates or a back-up plan.
– Stay within your pre-approved limit. It’s easy to chase a “deal we can’t afford” out of FOMO. Stay grounded, or you’ll end up with monthly payments that feel like a bad joke.
– Be prepared for counter-moves. If the seller resists, you may need to re-balance expectations, switch properties, or adjust contingencies.
– Keep everything documented. Emails, messages, and offers—keep a paper trail. It helps if negotiations get messy and you need a clear path back.
– Don’t go too far. A dramatic price cut right before exchange can damage your credibility and make lenders nervous. Keep things credible and, ideally, emotionally sustainable.
H3 deep dive: the legal side you should actually understand
– Contract structure matters. Your contract may include clauses about deposits, completion dates, and penalties for late completion. Read them. If you don’t, you’re trusting luck with your life savings.
– Deposits aren’t always guaranteed. In some places, deposits can be at risk if a sale falls through because of the buyer’s financing issues. Know where you stand.
– Time is money. Delays give room for gazundering or gazumping. Build realistic timelines into your plan and push for firm dates where possible.
– Remedies vary by jurisdiction. Some regions offer stronger protections for buyers or sellers than others. Talk to a local expert who actually knows the law in your area.
FAQ: quick answers to common questions
Is gazumping illegal?
Gazumping itself isn’t usually illegal. It’s often a breach of confidence or contract terms, depending on the jurisdiction and the specific contract language. Some places have protections in place to reduce the risk, but it’s not a blanket illegal act.
Can you sue someone for gazumping or gazundering?
Most people don’t sue over gazumping or gazundering. The costs and complexity of legal action usually outweigh the benefits. It’s more practical to seek compensation through specific contract penalties or to push for a re-negotiation with a new deal. Always consult a solicitor before you go down that road.
What should I do if I’m about to exchange and fear gazundering?
Keep lines open with your solicitor and the seller’s side. Ask for a firm completion date, request written confirmation of any price or condition changes, and insist on binding terms in the contract. Have your mortgage lender provide a firm readiness letter so you can avoid last-minute surprises.
What are the signs a seller might be tempted to gazump?
Common signs include a sudden surge of competing offers, pressure to move quickly, or hints that the seller has other interested buyers. If your agent senses a “we might have another bid,” you should push for a formal agreement or a lock-in if available.
How can I protect my deposit during negotiations?
Make sure your contract clearly states what happens to the deposit if the deal falls through (for reasons within both party’s control) and what happens if it’s outside either party’s control. A well-drafted deposit clause can save you headaches and money.
Conclusion: stay savvy, stay calm, stay moving
