One of the questions I’m asked most frequently as a buying agent is: Should I sell or buy my house first?
If you’re searching in the £1m+ market, you’ll already know that property decisions at this level carry more weight, more complexity, and—frankly, more risk.
It’s a fair question. On paper, both routes seem to have merit. But when you peel back the layers, the answer becomes far clearer. And as someone who spends every day helping clients secure the best homes at the best terms, I’ve seen the consequences—good and bad—of both approaches.
In this article, and assuming that you can’t buy without selling, I’ll break down:
• Why selling first almost always puts you in a stronger buying position
• How short-term renting can be a smart strategic move (and when it isn’t)
• Why delayed completions and other mechanisms can reduce disruption
• How a buying agent expands your off-market access and prevents long gaps between selling and buying
• And ultimately, why the question Should I sell or buy my house first almost always leans toward selling first.

Selling First Gives You the Power Position
When clients ask me ‘Should I sell or buy my house first’, my first instinct is to talk about leverage. In a competitive marketplace, especially in the £1m+ segment, leverage is everything. Sellers want certainty. They want buyers who can move quickly, who won’t have a long chain, and who won’t fall apart when “their buyer’s buyer” disappears overnight.
When you sell first, you become that ideal buyer. Here’s what that actually means:
You negotiate from strength.
A buyer who has already sold is infinitely more attractive to a seller. You’re not dependent on anyone else. You’re reliable. And reliability often leads to price reductions, accepted offers below asking, or victory in competitive bidding situations.
Estate agents will actively prioritise you because you help them get deals over the line without drama. This directly improves your access to the best properties.
You reduce fall-through risk.
Property chains break. Often. According to Rightmove and Zoopla data, around 25–30% of UK property sales fall through before completion (Rightmove House Price Index, Zoopla Market Reports). Being chain-free slashes that risk.
You can move quickly.
Speed matters. Particularly in areas like Surrey, Hampshire, The Cotswolds, and West Sussex—my core patch—high-quality properties rarely linger. Your ability to jump immediately can be the difference between buying the dream home… or watching it sell to someone else who was prepared.
This is why the question ‘Should I sell or buy my house first?’ overwhelmingly leans towards selling first if your goal is to get the best property at the best terms.

Renting Short-Term: A Strategic Advantage… for the Right People
Some clients hesitate to sell first because they worry about being “between homes.” That’s understandable. But temporary renting, done correctly, is one of the most powerful competitive strategies in the current market. I would guess that in my almost 40 years in the business, renting between homes is one of the most resisted options and almost always for the same few reasons.
The Good: Renting Gives You Sharp Buying Capability
For many of my clients, renting short-term bridges the gap perfectly. Here’s why:
You can pounce immediately
Properties in the £1m+ range are often purchased before they ever reach the open market. If you’re renting, you’re ready to move the moment the right home appears.
You negotiate the best price
A chain-free tenant is the buyer every seller dreams of: clean, organised, and able to exchange quickly. This almost always results in better negotiation outcomes.
You reduce emotional pressure
When clients try to buy before selling, they often panic-buy. They compromise when they shouldn’t. Renting gives you breathing space to make decisions based on quality—not urgency.
And if you’re wondering again: Should I sell or buy my house first, renting gives you the freedom to make the optimal move rather than being pushed into the available move.
The Bad: Renting Isn’t Great for Everyone
Of course, renting has downsides.
Pets can complicate matters
High-end rentals that accept pets aren’t impossible, but the choice is narrower. Some clients with larger dogs or multiple animals may struggle to secure something suitable quickly.
There are additional costs
Rent, storage, removals, temporary utilities, it all adds up. For many of my clients, this is a manageable inconvenience, and, as will be shown later in this blog, it is very likely to save you money in the long run. But it’s still an inconvenience worth acknowledging.
You may need to move twice
Some clients don’t mind this, but many do. Long-distance movers, downsizers, or those in transitional life stages often find it easier than expected. Others absolutely hate the idea.
As your buying agent, part of my job is to assess these factors honestly. For some, selling first + renting is the ideal strategy. For others, we structure the transaction differently.

Using Delayed Completions to Reduce Disruption
For clients who ask ‘Should I sell or buy my house first’ but dread the idea of temporary accommodation, it’s important to know that selling first doesn’t always mean moving out quickly.
You can exchange contracts on your sale and negotiate a delayed completion.
This means you:
• Lock in your buyer
• Secure your sale price
• Become chain-free
• Gain powerful buying leverage
• But stay in your home for 2, 3, even 6 months (depending on negotiation)
Delayed completions are common in higher-value transactions because the buyers often have flexibility. Many are cash buyers, investors, or people relocating without urgency.
This approach effectively gives you the advantages of selling first, without the downsides of immediate displacement.

A Buying Agent Reduces the Risk of a Long Gap Between Selling and Buying
One of the biggest worries behind the question ‘Should I sell or buy my house first’ is simply this: “If I sell first, it might take me ages to find something.”
This is where using a buying agent, specifically one who works full-time in the £1m+ space, changes the equation entirely.
Off-market access is everything
Around 30–50% of the properties I acquire for clients never hit the public market. They are discreetly offered to buying agents long before the portals see them.
Estate agents call us first because they trust we have serious, ready-to-go buyers.
You get first choice, not last choice
When you’re chain-free, I can put you in front of vendors before their properties are launched. This gives you:
• Negotiating priority
• Reduced competition
• Early access to the best stock
• A better chance of securing rare homes (country estates, perfect‐village cottages, high-spec modern builds, homes with acreage, etc.)
You avoid wasted months
Searching alone often means:
• Viewing the wrong homes
• Missing opportunities
• Being treated as “less urgent” by estate agents
• Letting the perfect home slip through your fingers
My job is to cut months, sometimes years, off your search time. That’s how clients who sell first avoid long gaps.
And when clients ask me, “Should I sell or buy my house first?” I can confidently say: selling first + using a buying agent is the combination that produces the best outcomes, the quickest acquisitions, and the least stress.

Selling First Mitigates Market Risk
The higher-value market moves differently from the mainstream market. Prices can shift quickly depending on:
• Interest rates
• International demand
• Stock availability
• Economic sentiment
• Political cycles
When you buy first, you expose yourself to timing risk:
Your sale could take longer than expected
Prestige homes often have smaller buyer pools. If your sale drags, you may be forced into price reductions while simultaneously paying the mortgage on your next home.
You may be forced to accept a lower price
If you’ve already bought, you lose negotiating power on your sale, and this can cost significantly more than a rental period or storage costs ever would.
You may end up bridging
Bridging finance can be a useful tool, but it is rarely the ideal option. Rates are higher, pressure is greater, and the timeframe is tight.
Selling first eliminates all of these stresses, and that’s why the question ‘Should I sell or buy my house first’ almost always has a more stable financial answer: sell first.

Real-World Experience: What Actually Happens When People Buy First
After years in this profession, I’ve repeatedly seen the same patterns unfold when clients decide to buy before selling:
• They compromise to secure something, often at a higher price
• They feel pressured because the clock is ticking
• They accept lower offers on their sale than they normally would
• They end up in a chain that weakens their negotiating position
• They pay bridging or duplicate mortgage costs
• Their stress levels skyrocket
This is not theoretical. It’s the lived experience of many people in the £1m+ market who didn’t plan correctly.
Contrast that with those who sell first:
• They negotiate strongly
• They move quickly
• They get access to better properties
• Agents prioritise them
• completion is smoother, calmer, and more controlled
The difference is night and day.

Final Answer: So… Should I Sell or Buy My House First?
Let’s put it plainly.
If your goal is to:
• Secure the best property
• Pay the right price
• Avoid a chain
• Reduce risk
• Move smoothly
• Keep control of negotiations
Accepting that this is not always possible, then the answer to ‘Should I sell or buy my house first’ is clear: sell first.
From there, you can:
• Rent short-term
• Negotiate a delayed completion
• Or line up your purchase with the help of a buying agent
Your strategy becomes tailored, flexible—and powerful.
