Has a sale ever felt wonderfully positive on Friday, only to go strangely quiet the following week?

The offer has been accepted. The seller is making plans. The buyer is excited. You update the listing to SSTC : and then everyone seems to disappear into a maze of solicitors, mortgage applications, surveys and unanswered emails.

This is one of the most vulnerable stages of a property transaction. Nothing is legally binding until exchange of contracts, and even a well-qualified buyer can lose momentum if the next steps are unclear or poorly managed.

The good news is that many early delays are avoidable. A structured approach to the period between offer accepted and exchange can protect the sale, reassure your clients and reduce the amount of last-minute chasing your team has to do.

Here are seven common mistakes : and what to do instead.

1. Treating offer accepted as the finish line

Winning the instruction and agreeing the sale are important milestones. They are not the end of the job.

The first few days after an offer is accepted are when commitment needs to be reinforced. Buyers may still be processing the financial decision they have made. Sellers may be wondering whether the buyer is genuinely proceeding. Both parties need to know what happens next.

If there is no clear contact shortly after the offer is agreed, the transaction can feel as though it has stalled before it has even started.

What to do instead

Make a structured “momentum” call within 24 hours. Confirm:

• The agreed price and key terms

• The buyer’s solicitor and mortgage broker details

• Whether the buyer has a full mortgage application underway

• The survey and valuation position

• The seller’s solicitor and paperwork progress

• The current chain position

• The next action for each party

Then send a short written summary. It does not need to be complicated. A clear list of who is doing what : and by when : can prevent confusion later.

Your clients should never have to ask, “What happens now?” Keep the next step visible and the sale is far more likely to keep moving.

2. Assuming the solicitors have been instructed

A memorandum of sale is not the same as a solicitor opening and progressing a file.

Buyers and sellers may have chosen their conveyancers but not formally instructed them. They may be waiting for ID checks, proof of funds, terms of business or an initial payment. Until those steps are complete, the legal work may not have properly begun.

Every day lost at this stage pushes searches, enquiries, mortgage checks and exchange further into the future.

What to do instead

Confirm instruction rather than assuming it.

For both sides, record:

• Solicitor or conveyancer name

• Named contact and direct contact details

• Date the firm received the memorandum of sale

• Whether the client has completed their ID and anti-money laundering checks

• Whether the file is formally open

• Whether the seller’s initial paperwork has been requested or returned

It is also worth checking that the memorandum of sale contains accurate information. Incorrect names, addresses, prices or solicitor details can create avoidable rework.

You are not trying to give legal advice. You are making sure the right people are connected and the file has genuinely started.

3. Treating a Mortgage in Principle as a confirmed mortgage

A Mortgage in Principle, Agreement in Principle or Decision in Principle is useful evidence that a buyer has had an initial affordability assessment. It is not a mortgage offer.

The buyer will usually still need to submit a full application. The lender may request more evidence, carry out a valuation and assess the property and the applicant in greater detail.

Delays can occur if payslips are missing, bank statements are incomplete, circumstances have changed or the buyer has not yet paid for the valuation.

What to do instead

Ask practical, neutral questions early:

• Has the full mortgage application been submitted?

• Is the application being handled directly or through a broker?

• Has the lender valuation been booked?

• Is any further information outstanding?

• Has the broker given an expected date for the mortgage offer?

Keep a note of the answer and agree when you will check again. You do not need to chase every day, but you do need to know whether the finance is progressing.

It is also sensible to remind buyers not to make major financial changes without speaking to their broker or lender. Changing employment, taking on new credit or making large purchases can affect an application.

Early visibility gives you time to address concerns before the seller becomes anxious.

4. Leaving surveys and valuations too late

A buyer may be happy with the property at the point of offer, then become concerned when the survey reveals damp, roof repairs, movement or other unexpected issues.

That does not automatically mean the sale will fall through. However, the sooner the survey is arranged, the sooner everyone can understand and respond to any issues.

Leaving it until later compresses the time available for further investigations, quotations or sensible discussions between the parties.

What to do instead

Check during the first week whether:

• The buyer has booked their chosen survey

• The lender valuation has been arranged

• The survey type is appropriate for the property

• The seller knows how and when the report will be dealt with

• Any follow-up inspections or specialist reports are needed

If a survey raises a concern, avoid dismissing it or making assumptions. Encourage the buyer to discuss the report with their surveyor and, where appropriate, obtain professional advice.

Your role is to keep communication calm and constructive. A concern dealt with promptly is much easier to manage than a concern discovered days before the buyer is expected to exchange.

5. Failing to check the chain properly

A chain is only as strong as the information you have about every link in it.

It is not enough to record that a buyer is “proceedable” or that another property is “SSTC”. You need to understand what those descriptions mean in practice.

Is the buyer selling another property? Has that sale exchanged? Is a cash buyer waiting for probate? Is someone relying on a mortgage offer that has not yet been issued? Has anyone set an unrealistic completion date?

What to do instead

Create a chain record that includes:

• Every buyer and seller in the chain

• Each property and the relevant agent

• Whether each link is no-chain, under offer or sold subject to contract

• Whether finance is cash, mortgaged or dependent on another sale

• Solicitor details for every known party

• The current target dates

• Any known risks or outstanding issues

Review the chain regularly, not just when someone asks for an update. A change at the top or bottom can affect everyone.

When the chain is mapped clearly, you can explain delays honestly and help clients make informed decisions. You can also spot risk before it becomes a crisis.

6. Promising dates before the transaction is ready

Clients understandably want dates. Sellers may be coordinating a purchase, buyers may be arranging removals and everyone wants certainty.

The temptation is to offer a confident exchange or completion date before the legal work, mortgage and chain are ready. Unfortunately, an optimistic date can create more stress than a realistic one.

Until exchange, either party can withdraw. Searches may take longer than expected, enquiries may uncover issues and mortgage offers can be delayed.

What to do instead

Talk in milestones rather than promises.

For example:

• Solicitors instructed

• Contract pack issued

• Searches ordered and returned

• Mortgage offer received

• Survey concerns resolved

• Enquiries answered

• Chain ready

• Exchange targeted

• Completion arranged after exchange

Explain that the target date will be reviewed as those milestones are reached. This gives your clients a useful sense of progress without creating false certainty.

It is also important to remind buyers and sellers not to make irreversible arrangements too early. They should take professional advice about rental notice, removals and financial commitments.

Good expectation management does not make you sound uncertain. It shows that you understand the process and are protecting your clients from avoidable disappointment.

7. Sending updates only when something changes

One of the most damaging communication gaps is the message that says nothing : or no message at all.

A solicitor may be waiting for a document. A buyer may be waiting for a mortgage update. A seller may be checking their phone repeatedly because they have not heard from anyone for a week.

Even when there is no major movement, a useful update reassures people that the sale is being watched.

What to do instead

Agree a communication rhythm from the start.

A weekly update should cover:

1. What has been completed

2. What is currently outstanding

3. Who is responsible for the next action

4. What you are chasing

5. Whether the target timescale has changed

6. When the next update will be provided

Keep updates specific. “The solicitors are progressing matters” is less helpful than “The buyer’s solicitor has received the search results and is waiting for one response from the seller’s solicitor.”

Make sure both buyer and seller receive appropriate updates. Do not allow one side to feel informed while the other is left guessing.

Consistent communication builds trust, keeps expectations realistic and gives you an opportunity to identify problems while there is still time to act.

A simple process protects the whole pipeline

Sales progression is not about sending more emails for the sake of it. It is about knowing what should happen next, who owns each action and when a quiet file needs attention.

Start with the first 24 hours. Confirm instruction, finance, surveys and chain position. Continue with regular, useful updates. Record conversations and follow up on agreed actions.

If your team has the capacity to do this consistently, a clear internal checklist can make a significant difference. If your pipeline is growing faster than your available time, support can help you maintain the same standard without adding another full-time salary or pushing admin into the evenings.

Our outsourced sales progression service for estate agents works as an extension of your existing business. We can manage progressions from memorandum of sale through to completion, provide regular updates and help keep buyers, sellers and professionals aligned.

You do not have to choose between growing your agency and giving every sale the attention it deserves. A calm, well-owned process can protect your pipeline, your reputation and your time.

If your sales are going quiet after offer accepted, take a look at the first ten days and ask where ownership becomes unclear. Small improvements at the start can prevent much bigger problems later.

And if you would like a little more capacity and expert support, we are here to help.
