Can You Buy a House Before Selling Yours? Pros, Cons & Risks

You have found the perfect home. The only problem? Yours is still on the market. So can you buy a house before selling yours?

Yes, you can. There is nothing in law that stops you from putting in an offer on your next home before your current one has sold.

But here is the thing. The real question is not “can you” but “should you”, and whether you can actually pull it off without losing the home you want.

I am Danny, and I have spent more than 20 years buying houses for cash in England and Wales. Every month, around 10 to 20 per cent of the people who come to us are in exactly this position. They have found the next place but not sold the last one.

Let me explain how it really works.

Can you buy a house before selling yours?

Legally, nothing stops you from making an offer.

Practically, two things decide whether it sticks: how you will pay for the new place, and how strong your offer looks to the seller.

Here is what most people miss. A seller does not just want any offer. They want an offer they can rely on. If you have not sold your own home yet, you are what the industry calls a buyer who is “not in a proceedable position”.

That is a polite way of saying: you cannot complete until something else happens first.

Why selling first is usually the safer play

Most of the time, I would tell you to sell first. Or at least to have a buyer locked in before you commit to a purchase.

Why? Because a good agent will protect their seller from people like you.

A reputable agent will advise a vendor not to accept an offer and take the property off the market unless the buyer is in a proceedable position.

So even if the seller likes you, their agent will often push for a buyer who has an Agreement in Principle with a mortgage lender, cash, or a sale already agreed. You can end up watching your dream home go to someone slower but more certain.

And there is a wider risk you need to respect: chains break. A lot.

Buy before you sell, and you are betting your move on a sale that has a better-than-one-in-three chance of falling apart.

Your options if you want to buy before selling

Sometimes you have no choice. The right house comes up now, not in three months. So here are the realistic ways to make it work.

Get a mortgage agreed in principle

Before you offer on anything, get a mortgage agreed in principle.

It shows the seller you are serious and that a lender is willing to back you. It will not make you fully proceedable on its own, but it strengthens a weak hand.

Consider a bridging loan

A bridging loan is short-term finance that “bridges” the gap between buying the new place and selling the old one.

It is fast, and it lets you buy now. But it is not cheap.

Bridging rates in 2026 typically run between 0.5 per cent and 1.5 per cent per month, which works out far higher than a normal mortgage once you annualise it (Fox Davidson, 2026). You also need a clear exit plan, usually the sale of your old home.

My honest view? Bridging works for some people. But if your old home takes longer to sell than you hoped, the interest stacks up fast and the pressure is real.

Sell fast to a cash buyer

There is a third route that competitors rarely talk about: sell your current home quickly for cash, so you become a proceedable buyer overnight.

This is what we do. We buy directly, with no chain and no estate agent in the way.

We can give you a cash offer within 24 hours, exchange in as little as 48 hours, and complete in two to four weeks. The average is around 28 days.

One concern people raise is timing. What if the dates do not line up perfectly? Could you be stuck in temporary accommodation or with your belongings in storage?

Our flexible contract lets you complete anytime from 14 days to four months. That means we can often complete on the same day you buy your next home, so there is no awkward gap in between.

The trade-off is price. We buy below market value, typically 75 to 85 per cent of the open-market figure. You swap a slice of the price for speed and certainty.

The tax you need to know about

Buying before selling means, for a while, you own two homes. That has tax consequences. This is one area where you should always take professional advice, but here is the lay of the land.

Stamp duty: the 5% surcharge

When you buy an additional property in England, you pay a stamp duty surcharge on top of the standard rates.

That surcharge is now 5 per cent, raised from 3 per cent on 31 October 2024 (GOV.UK, 2026). A lot of older guides online still say 3 per cent. They are out of date.

In Wales, you do not pay stamp duty at all. You pay Land Transaction Tax (LTT), which works quite differently from England’s system. Rather than a flat surcharge added on top of standard rates, Wales uses a completely separate set of higher rate bands for additional properties.

As of December 2024, those bands start at 5 per cent on the portion up to £180,000 and rise to 17 per cent above £1.5 million (GOV.WALES, 2026). If you are buying in Wales, check the current bands carefully, as the liability can look very different from an equivalent English purchase.

The good news: if the new home becomes your main residence and you sell your old one within 36 months, you can reclaim the surcharge. You must make the claim within 12 months of selling the old home (GOV.UK, 2026).

Capital gains tax: will you pay it?

Here is a common worry that is usually misplaced.

You do not pay capital gains tax when you sell your own main home. Private Residence Relief covers it, automatically, as long as it has genuinely been your main residence (GOV.UK, 2026).

CGT only bites on property that is not your main home, such as a second home or a buy-to-let. The current residential rates are 18 per cent for basic-rate taxpayers and 24 per cent for higher-rate taxpayers, with a £3,000 annual allowance.

So if you are simply moving home, CGT is rarely the thing to fret about.

What is the 6-month rule?

You may have heard of the “6-month rule” and wondered if it blocks your move.

It is not a law. It is a lending policy used by many mortgage providers. Most will not lend against a property the current seller has owned for less than six months, as an anti-fraud and money-laundering safeguard.

It only matters if you are buying from someone who bought very recently. It does not stop you selling your own home, and it does not apply to a cash purchase. Some lenders ignore it entirely, so always ask yours.

Real examples: how a fast sale saves the move

Theory is one thing. Here is how this plays out in real life.

We had a lady come to us who had her home on the market and had accepted an offer through her agent. She then found a property she loved and had her offer accepted.

The problem? She later discovered her agent had not properly qualified her buyers. They were not proceedable, because they had a property of their own to sell.

We stepped in with an acceptable cash offer, which she accepted. We completed within four weeks. That saved her chain and let her buy her dream home.

Then there was a gentleman who had sold his home three separate times. Each time, the sale fell through.

The last time, every query had been answered and every concern resolved, yet the buyers simply changed their minds. He did not want to gamble on a fourth attempt through the agent route. He wanted a certain sale, so he came to us, and we completed so he could finally move on.

I will be straight with you, though. A cash sale is not right for everyone.

If you have plenty of time and you are not under pressure, you will usually get more by selling on the open market. I tell people that honestly. Speed and certainty are worth paying for only when you actually need them.

So, what should you do next?

If you have the time, sell first, or at least line up a proceedable buyer before you commit.

If you cannot wait and the right home is on the table now, a fast cash sale can turn you into the strong, chain-free buyer that sellers and their agents want.

That is exactly what we do, every week, for people across England and Wales.
