What Happens If Your Buyer Pulls Out Before Completion?

A chain is simple enough to describe. You are selling your house and buying another one. You need the money from your sale to fund your purchase. The person you are buying from needs your money to fund theirs. And the person they are buying from needs the same again.

It works right up until one link decides it does not want to move any more.

What actually happens when your buyer pulls out?

Nothing legally. That is the problem.

In England and Wales you are not committed to a purchase until contracts are exchanged, and exchange does not usually happen until you are close to the completion date. Everything before that point is agreement without obligation. So the person buying your house can change their mind at any stage, owe you nothing, and leave you with the bill for everything you have spent.

I have seen chains break two months in. I have seen one break at six months. The money you have already put into your own purchase, the valuation, the solicitor, the searches, is gone either way. What you have lost is the funding for your onward purchase, because the money was going to come from the sale that has just evaporated.

And the pressure does not stop with you. The person you are buying from is now stuck too, and so is the person above them.

Why would a buyer pull out that late in the process?

Almost never out of bad faith. In my experience it is one of a handful of things:

• They have separated, and the purchase was based on two incomes
• One of them has been made redundant
• The deposit is no longer there, often because it was coming from somewhere else that fell through
• A death in the family

None of that is anybody’s fault, and none of it helps you. It is worth understanding though, because it tells you something useful: the buyer who pulls out is usually gone for good. You are not going to talk them round.

Can you not just put it back on the market?

You can, and plenty of people try. The maths is what defeats it.

Say you are four months into the process. You remarket, you get viewings, you accept an offer. Your new buyer is now on day one. They need a mortgage application, a valuation, searches and the full legal process, and that is before anything goes wrong.

Meanwhile the top of the chain has been waiting four months already. They are not going to wait another four. They will remarket, and you will lose the house you were buying.

So remarketing is the right thing to do. It is just not, on its own, a way of saving the purchase.

How does bridging keep the chain together?

By doing exactly what the name says. We bridge the gap.

Instead of waiting for your sale to produce the money, we raise it against the property you already own. You complete on the new house on the original date, the chain holds, and your old house goes back on the market with no deadline hanging over it. When it sells, the sale proceeds repay the bridge. If you want the mechanics in full, we have set out how to finance a chain break step by step.

Here is a real one. A retired couple were midway through a chain, selling a house worth around £800,000 with no mortgage on it at all, and buying a £400,000 property by the coast. They had already chosen the kitchen. Their buyer pulled out.

We put a first charge bridge on the house they owned and drew £400,000 net, which is half the value of the property. That bought the new house outright. Their old house went back on the market, and the plan was always that the sale would repay the bridge.

The useful part of that deal was the valuation. They had already had an £800,000 offer accepted on the house, so there was recent evidence of what it was worth. The lender accepted a desktop valuation instead of sending a surveyor. That took a couple of hours. A physical valuation would have taken a fortnight to book and another week for the report.

What if you still have a mortgage on your house?

You can still do it. It is called a second charge bridge, and it sits behind the mortgage you already have rather than replacing it.

Look at your title deeds and you will see that the lender who gave you your mortgage holds the first charge. If you sell, they are paid first. A second charge lender is paid after them. That is more risk, so second charge lenders lend a little less against the same property.

There is one extra step. Your existing lender has to consent to a second charge being registered, and some will not, as a matter of policy rather than anything to do with you. That needs checking early rather than late.

The second deal I will give you shows what is possible. A family home worth around £850,000 with a first charge mortgage of about £150,000 on it, and an onward purchase at £650,000 that had to be bought outright. There was no time to arrange a residential mortgage on the new house.

We ran two bridges at once, with the same lender. A second charge on the house they were selling, and a first charge on the house they were buying. Between the two we raised the full purchase price and the stamp duty. The chain completed, and their original house has since sold and repaid both facilities.

What about the extra stamp duty?

This catches people, and it is the part nobody mentions when they tell you bridging will save your purchase.

If you complete on the new house before the old one has sold, then on the day you complete you own two homes. That means the higher rates of stamp duty apply to the purchase, even though the new house is going to be your only home once the old one goes.

You do get it back. Where you are replacing your main residence, you can reclaim the higher rate element once you sell the previous main home, provided that sale happens within three years of the purchase. The claim itself has its own deadline, generally twelve months from the later of the sale or the filing date of the return on the new property.

Two practical points. First, you have to find that money on completion day, which is cash you were not planning for, so the bridge usually has to cover it, as it did on the second deal above. Second, the three year window is another reason the exit matters: it is not just the loan term you are working to.

Stamp duty is tax, not mortgage advice, and it is not my area. Check the position on your own purchase with your solicitor or an accountant. I am raising it because it changes how much you need to borrow, and that part is my area.

What if your house does not sell in time?

This is the question everybody asks, and it deserves a straight answer rather than reassurance.

If the loan reaches the end of its term and the house has not sold, you are in default. What that costs you depends entirely on which lender you are with, and the difference between them is enormous.

Some will increase the rate sharply and apply default charges. They will get their money. Others take a more practical view: they will push the term back a couple of months, it will cost you something, but they will not put you in default, because what they actually want is for the house to sell and the loan to be repaid.

Almost nobody compares lenders on that basis. They compare rates, loan to value and whether a desktop valuation is acceptable, and they never ask what happens in month thirteen. Everyone is certain the house will sell. It is a beautiful house in a lovely spot, of course it will sell.

So that is the first thing I look at. Not just what the loan costs if everything goes to plan, but what it costs if it does not.

The second thing is the exit, and that work happens before we approach anybody. Is the house genuinely sellable? Is it somewhere with real demand, or somewhere very quiet? It has sold once already, so how long did that take and how many viewings did it get? And how much headroom is there in the loan to value, because if you are at half the value of the house you can drop the asking price to get a quick sale and still be comfortable. At the top of the range you cannot.

The lender does the same work. They will look at the property, the area and what is selling nearby, and they will want a valuation. Most will not release the money until the house is actually on the market, and a good one will keep in touch while it is. If you are six months in with no viewings, that is the moment to talk about price, not month eleven.

None of that removes the risk. You need the house to sell. What it does is make sure you have looked at the risk properly before you take it on, instead of finding out about it afterwards.

How quickly can it be arranged?

The fastest I have done one took days, but that was a single property with a desktop valuation and nothing complicated attached to it.

On a chain break you are usually dealing with two properties, and often a regulated lender, which means more compliance and a smaller pool of lenders to choose from. Four to six weeks is a realistic planning assumption.

What sets the pace is almost always the valuation and the solicitors, not the lender. If you can get a desktop valuation accepted, as those downsizers did, you take a fortnight out of the timetable in an afternoon. That is the first question worth asking on day one.

Questions people ask when their buyer pulls out

Can my buyer legally pull out before exchange?

Yes. In England and Wales neither side is committed until contracts are exchanged, so a buyer can withdraw at any point before that and owes you nothing.

Who pays the costs if the chain collapses?

You do, for your own side. Your survey, your searches and your legal costs to that point are not recoverable from a buyer who pulls out before exchange.

Can I borrow against a house that still has a mortgage on it?

Yes, through a second charge bridge that sits behind your existing mortgage. Your current lender has to consent to it, and a few will not, so it is worth checking early.

How much can I borrow against my current home?

It depends on the property, the location and how credible the sale is. As a guide, first charge lending on a chain break usually runs to around 75 per cent gross, second charge nearer 60 to 65 per cent gross, with a small number of lenders going to 80 per cent net on the right deal and pricing accordingly. Ranges correct as at 14 October 2026 and they move with the lender and the deal, so please call us to confirm what is available on yours.

Do I pay extra stamp duty if I buy before I sell?

Yes, the higher rates apply because you own two properties on completion day, and you reclaim the difference when you sell your previous main home, as long as that happens within three years. Take the detail from your solicitor.

What happens if my old house still has not sold at the end of the term?

You are in default, and what that costs depends heavily on which lender you are with. It is one of the main things worth comparing before you choose one.

The short version

A buyer pulling out is not the end of your purchase. It is the end of your funding, and funding is a problem with solutions.

What it needs is somebody looking at the whole picture early: what the houses are worth, what is already secured against them, how quickly the old one will really sell, what the stamp duty does to the figure you need, and what happens if the sale takes longer than anyone expects. Get that right at the start and a chain break becomes an inconvenience rather than a disaster.

If your chain has just broken, or you can see it coming, send me the two properties and where you are in the process and I will tell you honestly what is achievable. If it does not work, you will hear that too, and early enough to do something else.
