What Does Sold Subject to Contract (SSTC) Mean?

If you’ve been browsing property listings, you’ve likely seen the conveyancing term SSTC (short for Sold Subject to Contract). But what exactly does it mean for buyers and sellers?

The different stages in the property buying (or selling) journey can be very confusing. We know how important it is to understand where you stand once an offer has been accepted, and what can still change. Whether you’re buying or selling, knowing what SSTC really means helps you navigate the process with more clarity and confidence.

In this guide, we explain the ins and outs of SSTC, what happens next, and how to protect your position until the sale becomes legally binding.

What Is SSTC?

In simple terms, SSTC means an offer has been accepted on the property, but the sale hasn’t legally completed. The property is moving forward in the process, but contracts haven’t yet been exchanged - so the deal isn’t binding.

For now, it’s off the market in practice but not in law. This means both parties can still change their minds, and the seller is legally required to consider any higher offers that come in (known as gazumping).

Want to avoid gazumping altogether? Purplebricks offers an optional solution. With the Purple Pact for buyers, you can lock in your offer with a small holding deposit, removing the property from the market and preventing competing offers. It’s a gazumping-free zone - once both sides commit, the sale is legally secured. Only around 5% of sales fall through with the Pact, giving both buyers and sellers more peace of mind.

What Happens After a Property Is Marked SSTC?

Once a home is SSTC:

• The conveyancing process begins – solicitors for both parties start preparing and reviewing legal documents.

• The buyer arranges their mortgage – including final approval and a formal mortgage offer from their lender.

• Surveys are booked and carried out – such as a homebuyer’s report or structural survey, depending on the buyer’s needs.

• Searches and legal checks are ordered – covering title deeds, planning issues, local authority information and more.

• Draft contracts are drawn up – including details of the sale, fixtures and fittings, and target completion timelines.

This stage can take several weeks (or longer if part of a chain). 

Can I Still View or Offer on a SSTC Property?

Technically, yes. While a home marked as SSTC is no longer actively marketed, sellers are still legally obliged to consider any new offers that come in. This means gazumping can happen, although it’s not common.

In most cases, sellers choose to honour the original agreement - especially when both sides are progressing smoothly. If you’re interested in a SSTC property, it’s worth letting the agent know. They can keep you updated in case the sale falls through.

What’s the Difference Between Under Offer and SSTC?

• Under Offer: An offer has been made and is under consideration

• SSTC: The offer has been accepted, but contracts haven’t been exchanged yet

Basically, SSTC is one step further along in the sales journey than Under Offer.

Can SSTC Sales Fall Through?

Yes. A property marked SSTC isn’t guaranteed to sell. While an offer has been accepted, the sale isn’t legally binding until contracts are exchanged — and a lot can change in the meantime.

Here’s some common reasons sales fall through include:

• Survey issues: Major problems like damp, subsidence or roof damage can spook buyers or lead to renegotiations.

• Mortgage complications: A buyer’s mortgage might be delayed, reduced or even declined after application.

• Gazumping: Another buyer makes a higher offer, and the seller accepts.

• Gazundering: Just before exchange, a buyer reduces their offer — putting pressure on the seller to accept or risk starting over.

• Delays in paperwork: Missing documents or slow responses from solicitors can cause frustration and lead to fall-throughs.

• Change in circumstances: Buyers or sellers may experience job loss, family changes or second thoughts.

• Chain collapse: A linked sale or purchase elsewhere in the chain breaks down, halting progress for everyone involved.

These risks are why it’s so important to keep momentum going and consider protective options like the Purple Pact, which helps reduce fall-throughs and provides more certainty for both parties.

What Does SSTC Mean for Buyers?

If you’re the buyer, SSTC signals the start of the legal and financial process that takes you from offer to ownership. The seller has accepted your offer, but the sale isn’t legally binding until contracts are exchanged, so this next stage is all about moving things forward efficiently.

At this point, your solicitor will begin the conveyancing process, raising enquiries, checking legal documents, and guiding you through the next steps. You’ll also need to arrange a survey, progress your mortgage application, and stay in close contact with your lender and legal team.

While this part of the journey can feel slower than expected, it’s where most of the groundwork happens, and being proactive really helps. Respond to any paperwork quickly and stay in touch with your estate agent.

What Does SSTC Mean for Sellers?

For sellers, SSTC means you’ve accepted an offer and the legal process is underway, but the deal isn’t done just yet. Until contracts are exchanged, either party can still walk away, so it’s important to keep things progressing and avoid unnecessary delays.

Your solicitor will now start preparing the contract, answering buyer enquiries, and working with the buyer’s solicitor to move things forward. The smoother this process goes, the faster you’ll get to exchange and completion.

Although you may still receive interest or even higher offers at this stage, accepting a new offer could slow the sale and risk losing your original buyer’s trust. For most sellers, staying the course with a committed buyer is the best way to reach completion without added stress.

Final Thoughts: Stay Informed, Stay in Control

SSTC is a step in the right direction, but it’s not the finish line. Whether you’re buying or selling, understanding what happens at this stage helps you avoid surprises, reduce delays and protect your sale.

With the right support, clear communication and legal preparation, most SSTC transactions progress smoothly to completion.
