When a ‘sale’ isn’t a sale: rethinking certainty in today’s property market

The language of property transactions has long carried a reassuring sense of progression. A property is listed, viewings take place, an offer is accepted and the matter moves forward under the familiar label of ‘sale agreed’. For many years, that sequence has been treated as a reliable indicator that completion will follow in due course. Increasingly, however, that assumption is being tested.

Current state of play

The residential property market is often described as slow, but recent data suggests something more complex. At the time of writing, stock levels now exceed 715,000 homes nationally, significantly above historical norms, while over the last 12 months, only around 53% of properties listed in estate agents’ windows proceed to exchange and completion. Nearly half of all instructions fail to reach a concluded sale.

This matters in probate practice, where property frequently represents the principal asset of an estate and the primary source of liquidity. The challenge is no longer simply achieving an offer but ensuring that the offer represents a credible route to completion. Any transaction may still carry a meaningful risk of delay, renegotiation or collapse.

Part of the difficulty lies in how progress is measured. Traditional markers such as ‘under offer’ or ‘sale agreed’ provide a sense of forward movement, yet they do not reflect the underlying strength of the buyer, the resilience of the chain or the level of conditionality attached to the agreement.

The numbers

The data reinforces this. While approximately 368,000 homes have been marked as sold subject to contract this year, only around 214,000 have progressed to exchange. Fall-through rates remain high, with recent weekly figures exceeding 25%. The gap between agreement and completion is not marginal – it is a defining feature of the current landscape.

Time adds a further dimension. A property that remains on the market for an extended period does not simply take longer to sell; evidence from TwentyCi indicates that once a property has been marketed for more than twelve weeks, its probability of selling falls sharply, to just 14.5%.

There is also a widening gap between expectation and outcome, with the difference between asking prices and agreed sale prices approximately 25%, compared with a long-term norm closer to 16-17%. The initial positioning of a property does not always align with buyer sentiment, leading to prolonged marketing periods, incremental price adjustments and, in some cases, eventual withdrawal.

What this means for probate

For lawyers advising on probate matters, this introduces a more nuanced set of considerations. The legal framework remains unchanged, and the need for appropriate valuation and professional advice is as important as ever. What is evolving is the context in which those decisions are made. The route by which a property is brought to market can materially influence not only price, but also the likelihood of completion.

This is particularly relevant where properties require modernisation or fall outside mainstream market expectations; which is the case for a significant proportion of probate stock.

Unmodernised properties, which often languish on estate agents’ books through repeated reductions, frequently perform exceptionally well when multiple buyers compete openly under binding conditions. The result is both stronger pricing and a more certain path to completion.

The advantages of auction

The difference is structural. Where a traditional sale relies on a single buyer making a conditional offer, auction creates an environment in which commitment is built into the process. Contracts exchange when the hammer falls. There is no renegotiation, no survey-based chipping, no protracted chain risk. For properties that sit outside the preferences of the mortgage-dependent market, this matters considerably.

The nature of the asset increasingly dictates the most effective route – and there is a growing case for considering alternatives earlier in the process rather than as a final step.

This does not require a departure from established practice, but it does suggest a broader framing of advice. Rather than treating a sale as a binary event, it may be more accurate to consider it in terms of probability – influenced by buyer commitment, market conditions and the degree of competition for the asset. Executors and beneficiaries are less concerned with the formality of a sale being agreed than with the confidence that it will conclude within a reasonable period and on terms that reflect the property’s true market position.

What emerges is a shift in emphasis. Certainty, once assumed to follow from process, is now something that requires more deliberate consideration. Lawyers advising on property within estates are navigating two parallel dimensions: the legal requirements of the transaction and the practical likelihood that a chosen approach will result in completion.

Conclusion

The phrase ‘sale agreed’ will no doubt remain part of the professional vocabulary, but its meaning is evolving. In a market where outcomes are less predictable and timelines more variable, it serves as a reminder that agreement is only one stage in a process that must still culminate in exchange. Ultimately, the distinction between a sale that is agreed and one that is achieved is becoming more pronounced.

In 2026, the firms that will serve their clients most effectively are those prepared to look past habit and consider which disposal route genuinely aligns with the asset in front of them. For unmodernised probate properties in particular, the evidence increasingly suggests that competitive, time-bound methods deliver outcomes that conventional marketing cannot reliably achieve. Not in every case, but in enough cases that earlier consideration is becoming difficult to justify withholding.
