Selling and buying as one move — the private client approach

One move · Private client advisory

Selling and buying as one move

Most people moving house engage a selling agent for one half and, if they are thorough, a buyer’s agent for the other. Two service providers, two mandates, no obligation to speak to one another. At Weiss Real Estate your interests sit with one point of contact — a single person who understands what you are actually trying to achieve, and who stays with it from the first conversation to settlement on both sides.

Selling and buying as one move in Sydney's Eastern Suburbs — private client property advisory with Alan Weiss, Weiss Real Estate
One adviser, both sides of the move · Eastern Suburbs

Very few people sell a home simply to hold the proceeds. They sell because something next has to happen. The house has become too large for two. The children have settled across the harbour and the parents wish to follow. The capital tied up in one property would do more useful work arranged another way entirely. The sale is not the end of anything — it is the first half of a single decision.

The industry insists on treating it as two. There is the agent who sells your home, whose mandate expires the moment the contract is signed. There is, if you engage one, the agent who helps you buy, whose involvement began only when you walked through the door. Each is paid on one side of one transaction. Each is doing precisely what they were engaged to do.

Nobody is standing at the seam — where the timing, the money and the risk all actually live.

Selling agent your home your next home Buyer’s agent no one owns the middle
How it usually works. Two advocates, each for half — and a gap where the timing, money and risk actually live.

One person, holding your interest

Consider how you are looked after everywhere else that money of this size is involved.

A private banker is one person whose job is your interest. Not a product. Not a transaction. They hold the whole position — what is coming due, what is illiquid, what has to happen in which order, and what it costs to get that order wrong. They coordinate the specialists rather than competing with them. They are judged on where you stand in three years, not on what closed this month. And discretion is assumed rather than advertised.

That model exists because certain decisions are too consequential to be handled in pieces by people who each see only their own piece.

Property never built the equivalent. What it built instead was two separate service providers. The selling agent is engaged by you to achieve one outcome. The buyer’s agent, if you engage one at all, is engaged to achieve a different outcome. Both may be entirely competent. But they are not synchronised, and nothing in either arrangement requires them to be — they answer to different mandates, on different timetables, and in many cases they will never speak.

The result is that the person with the most complete understanding of your sale has no involvement in your purchase, and the person negotiating your purchase has never seen the evidence that set your sale price. Two halves of one decision, held by two people, neither of whom is accountable for how the halves fit together.

At Weiss Real Estate your interests are entrusted to one point of contact — a single person who understands your property goals, holds both sides of the move, and remains accountable for the result of the whole.

Two competent providers, working to different mandates, is not the same as one adviser working to yours.

Two service providers
One point of contact
Who holds your goals
Two providersEach knows its own half. Neither has been asked to understand what you are ultimately trying to achieve.
One point of contactOne person, from the first conversation to settlement on both sides. The goal is the brief, not the listing.
Sell first or buy first
Two providersFalls between them. Neither party is engaged or paid to decide it, so it defaults to whoever you spoke to first.
One point of contactDecided deliberately, with you, before either side begins — on your circumstances and the state of both markets.
Market knowledge
Two providersRead twice, by two people, to two different standards. The reading behind your sale price leaves with the selling agent.
One point of contactRead once and used twice — to sell well, and eight weeks later to stop you overpaying.
If the timing slips
Two providersEach manages its own side. The exposure between them belongs to you.
One point of contactOne person manages the gap, the contingency and the settlement alignment across both properties.
Accountability
Two providersDivided. Two mandates, each expiring at a contract.
One point of contactUndivided. One mandate, which ends when you are settled in the next home.

Why this matters more in the market we are in

In a rising market the cost of fragmented advice is hidden. Everything appreciates while you deliberate, and mistakes of sequencing get papered over.

That is not the market we are in. Cotality’s national Home Value Index fell 0.9 per cent in August — a fifth consecutive monthly decline, leaving values 3.6 per cent below the March peak. Sydney led, down 1.4 per cent over the month and 7.1 per cent below its February high. Ninety-three per cent of capital city suburbs recorded some decline through winter, and sales volumes are running roughly 15.5 per cent lower over the year.

More to the point for anyone reading this page: the fall is not level.

That single fact reorganises the whole question — because what determines your outcome is not the value of your home on its own. It is the distance between what you are leaving and what you are entering. When the top of the market falls faster than the middle, that distance changes, and it changes in different directions depending on which way you are travelling.

cost on your sale saving on your purchase net position +$200k $0 −$200k Moving up Moving sideways Moving down $4m → $8m $5m → $5m $8m → $4m
The same 5 per cent fall, three different outcomes. Sell for less and buy for less: whether that leaves you ahead or behind depends entirely on your direction of travel. Illustrative arithmetic assuming an equal percentage fall on both sides, before costs and before negotiation. Not a forecast or a valuation.

Three families in identical houses on the same street can face three different answers this spring. None of them will find that answer in a headline, and none of them will get it from someone who is only looking at one side of their move.

Meanwhile the mechanics have tightened at both ends. The Reserve Bank held the cash rate at 4.35 per cent on 11 August, after three increases earlier this year, with the Board explicitly leaving the door open to another. Changes to negative gearing and the capital gains tax discount passed Parliament on 25 June and take effect from 1 July 2027. And the auction market has spent the winter well below where it sat a year ago.

Fewer buyers. Longer campaigns. More stock. Higher stakes on getting the order right. This is the market in which fragmented advice becomes expensive.

A good adviser is not asking whether it is a good time to sell. They are asking whether the spread works for you.

The mandate

This is what an engagement actually contains. It is a mandate, not a listing.

one mandate the sale the purchase your accountant your solicitor your lender coordinated, not replaced
One adviser, on your side of the table. Both halves of the move held together, and your existing advisers brought in at the right moment rather than worked around.

One position, not two transactions

We begin with the whole picture — what you own, what you are trying to reach, what the timing constraints genuinely are, and what the net movement needs to be for the move to make sense. Not simply “what is your home worth.”

The sequencing decision, made deliberately

Sell first or buy first is the single question that most determines whether this goes smoothly or becomes the hardest year you have had. It gets decided on your circumstances and the state of both sides of the market — not on whichever side happens to be in front of you.

The sale, personally handled

Preparation, method, pricing strategy, campaign and negotiation. Run by me, not delegated to an associate you have not met. In a market clearing at these rates, method is not a formality.

The purchase, with the same knowledge used twice

The reading of comparable evidence that gets you a strong sale is the same reading that stops you overpaying eight weeks later. It is wasted if it walks out the door with the selling agent.

The seam between them

Settlement alignment, bridging exposure where it is needed, the contingency if one side slips, and the specific question of who is carrying the risk on any given day. This is the part that has no owner in the conventional arrangement.

Coordination, not duplication

I work alongside your accountant, solicitor and broker. I do not replace them, and I do not give financial, taxation or legal advice. What I do is ensure the property decision reaches each of them at the right moment and in the right shape.

What this is not

It is not vendor advocacy. That is a separate service — engaging and managing a selling agent on your behalf — and it is available here if that is the better fit.

It is not a buyer’s agent bolted onto a listing.

And it is not a service that scales. I keep client numbers deliberately small, because a mandate of this kind cannot be run in volume and I have no interest in pretending otherwise. If I am at capacity when you call, I will tell you so.

Who it suits

It suits you if

  • You are selling and buying within roughly the same period, and the two are financially connected.
  • The property represents a substantial share of your position rather than one holding among many.
  • You would rather have one person accountable for the outcome than two people accountable for halves.
  • You value being told when you are wrong.

It probably does not if

  • You are selling with no intention of buying again.
  • You want the lowest commission available and nothing else matters.
  • You would prefer a large team and a high-volume brand. Both exist, and some people genuinely prefer them.

How an engagement runs

01

An honest conversation

No obligation, no presentation, no folder of past sales. What you are trying to do, what is constraining it, and whether I am the right person for it.

02

The position, in writing

An appraisal of your home, a realistic view of the segment you are buying into, and the net movement between them at today’s numbers.

03

The sequence, agreed

Sell first or buy first, why, what the contingency is, and what would cause us to change our minds.

04

Execution, both sides

The campaign and the search, run in parallel by one person, with the timing managed between them.

05

Settlement

The dates aligned, the exposure understood, and no gap where nobody is watching.

The questions worth asking me

What proper counsel sounds like

  • Given my sale and my target purchase, what is the real net movement — and is now the moment it is widest in my favour?
  • Which direction am I actually travelling, and what does the current divergence between price bands make that worth to me in dollars?
  • Should we secure the purchase before the sale, or use the certainty of a sale to negotiate harder on the buy?
  • Is auction the right method for my property in this market, or does the clearance evidence argue for a considered private campaign?
  • If timing slips on either side, what is the contingency, and who is managing it so I am never exposed on both properties at once?

If your current adviser cannot answer the first of those, they are advocating for half of your move.
