Key takeaways

  • A property chain connects together several buyers and sellers, which means that your move will depend on the success of the actions of others.
  • The upward chains are the sellers who are above you, and the downward chains are the buyers who are below you.
  • By purchasing a property that is not part of a chain the need for an onward purchase is eliminated and the process is considerably accelerated.
  • The sale can be saved if a buyer or a seller withdraws by moving into rented accommodation or using storage.
  • The best ways to ensure that your transaction proceeds are to get a proactive conveyancer and book a RICS surveyor as early as possible.

The housing market has a great number of elements to it, and one of the most important factors affecting how quickly and successfully you make your move is the arrangement of the people who are buying and selling—the first thing you need to do if you want to take control of your move and avoid unnecessary stress is to understand how these connected transactions function.


What is a property chain?

A property chain involves a series of connected buyers and sellers, with each transaction depending on the others succeeding. If one individual has a delay or decides to pull out, the rest of the people in the chain are also impacted. The timeline when you are purchasing a house is determined by chain dynamics. Typically the person at the end of the chain is a first-time buyer or an investor who does not need to sell a property in order to finance their purchase, while at the top of the chain is someone who is selling a house without having to buy one themselves, for example a developer selling a newly built property or a family selling a house that they have inherited.

In order to be able to afford their next house, everybody who falls between these two points needs their present home to be sold. Since the mortgage funds have to be transferred one after another on the day of completion, a delay by just one lender or conveyancer can bring the whole process to a standstill. The Law Society repeatedly stresses the importance of clear communication among all the legal representatives when handling such connected transactions.

To ensure your transaction goes as smoothly as possible, it helps to have a legal expert who stays in regular contact with the other parties involved. You can get a number of conveyancing quotes using Moving Compared to find a professional who will help progress your purchase. If you aren't clear about the various legal steps involved, it will be helpful to read some information on conveyancing so that you can understand what your solicitor is doing behind the scenes.

Understanding upward and downward chains

To fully grasp your position in the market, you need to look at the transaction from two directions:

  1. An upward chain involves the individual who is selling the property you wish to buy and the people from whom that person is buying their next home. In the event that the highest-level seller is unable to find a house to purchase or if their legal proceedings come to a standstill, your purchase will not be able to go through.
  2. A downward chain consists of the people who buy afterwards. This covers the person who is buying the house you currently own and all those who then buy a house from them. In the event that the individual at the lowest point in the chain is unable to obtain their mortgage, the money cannot pass up the chain and therefore you will not have the funds needed to buy the next property.

When you are buying for the first time you only need to consider the upward chain since you have no property to sell.

Pro tip: Before making an offer or accepting one, you should always ask the estate agent about the length of the chain both in front of and behind you. Once you know how many linked transactions there are, you can set realistic expectations and plan your moving schedule accurately.


What does a chain-free house mean?

A house that is chain-free is one where the property being sold does not rely on the seller having to buy another property; this kind of situation usually occurs with empty homes, with new builds, or when the sellers decide to move into rented accommodation. If you are looking for a chain-free property, then you are seeking a deal that has no upward chain. Such a situation is very desirable in the UK housing market because, since there is no need to wait for the seller to find and purchase their next house, the legal work can go ahead on your own schedule.


The pros of chain-free buying

Buying a house without an upward chain has a number of clear advantages. The most obvious of these is that it is quicker. According to data from HM Land Registry, transaction times can vary greatly throughout the UK, but eliminating linked dependencies is a known method of achieving faster completion.

A great deal else is the element of certainty. If you buy a house without establishing these connections then the risk of the sale going through being blocked because of another person's mortgage rejection or a poor survey report from three links along the chain is reduced. All you have to concern yourself with is your own mortgage and your own property inspections.

When you mortgage a property and there is no upward chain, you should take advantage of the situation by getting your professionals involved right away. You can use our platform to compare the quotes from surveyors and make sure that your property condition inspections are carried out without delay. It is important to know what kind of survey you need, and you will find detailed explanations in our advice and guides section on surveys.


What happens if someone pulls out of the property chain?

When a person withdraws before exchanging contracts, the associated transactions generally fall through. Both the buyers and the sellers have to pay out the legal fees and the cost of the surveys, and the search for a new buyer or a new property has to be restarted.

In the UK housing market, an accepted offer is not legally binding until the contracts have been exchanged. It is therefore possible for anyone to decide to back out, go through a change in financial situation, or choose to reduce their offer right at the last minute. The emotional and financial impact when a link breaks can be severe. If the buyer decides to withdraw, you will not be able to go ahead with your purchase of the next property unless you can quickly find a new buyer or obtain a bridging loan. On the other hand, if the seller pulls out, you will be left without a house to move into, even though the buyer will still be expecting to move into your present property.


Strategies for breaking the chain

Even though a collapse is disappointing, it is at times a strategic and beneficial step for saving a transaction.

If the person you are buying from is having difficulty in finding the next house and is delaying the process, they may choose to move into rented accommodation or stay with family. In that case, the connection is broken and they then become a chain-free seller, which enables your purchase to go through.

Instead, if your seller decides to back out but you have a buyer who really wants to move into your house, you may decide to break the link on your own. You could go ahead with the sale of your home, move into a short-term rental and store your possessions in a storage unit as you search for a new property to purchase.

If you want to break the link to save your sale, you'll need a dependable way to transport and store your possessions. You can find removal companies using Moving Compared that are registered with the British Association of Removers, and many also offer secure storage alongside their standard moving services. Additionally, we provide practical advice and tips on packing and moving in our advice and guides sections to help you prepare for a two-step move.


How can you keep your property chain moving?

You will be able to keep your property chain going if you employ a proactive conveyancer, get back to anyone who sends you a legal enquiry promptly, and arrange for a surveyor as early as possible. Keeping all the parties properly in communication avoids unnecessary delays and ensures that the whole transaction stays on track.

The quicker your action and that of your selected professionals will be, the faster the process will go. As soon as your offer has been accepted you must ask your conveyancer to act. Returning your first set of documents, giving proof of funds and paying for the local authority searches within the first few days will establish a good tone for the rest of the transaction.

It is just as important to book a RICS surveyor as soon as possible. Surveyors are usually booked weeks in advance, so if you delay doing so you may end up blocking the whole queue of buyers and sellers while you wait for your property report to be produced. Lastly, you should keep in regular contact with your estate agent since they usually have the best overall view of the chain of buyers and sellers and can get other agents in the queue moving if the process slows down.

Pro tip: Start decluttering and packing non-essential items early. Once the completion date is agreed across all linked parties, it often happens quickly. Being prepared reduces your stress during those final frantic weeks.


Summary

Understanding the dynamics of linked property transactions gives you a distinct advantage in the housing market. To summarise, the major ways to keep your move on track are to prepare thoroughly, aim for a chain-free property if possible, and understand your place in both the upward and downward chains. It is also essential to respond quickly to legal and administrative requests, to maintain communication with all parties, and to enlist skilled professionals early in the process. By hiring effective conveyancers, booking surveys promptly, and organising removals in advance, you increase your chances of a smooth and timely completion.
