We Buy Any House: How Fast Can You Actually Complete a Sale?

If you’ve ever typed “sell my house fast” into Google, you’ve almost certainly come across the phrase “we buy any house.” It’s an appealing promise — a guaranteed sale, no chain, and a process that can be measured in days rather than months. But how quickly can you really complete, and what should you expect along the way? As a British property professional, I’m here to walk you through the real-world timeline, cut through the marketing fluff, and help you decide if a fast cash sale is right for your situation.

What Does “We Buy Any House” Actually Mean?

In the UK, we buy any house companies are typically direct property buyers who use their own cash (or private funding) to purchase homes quickly. Unlike a traditional estate agent sale, they aren’t reliant on a buyer securing a mortgage or a chain completing. Their business model is built on speed and certainty — often buying below market value in exchange for a guaranteed, hassle-free transaction. Because they use their own funds, they can move at a pace that leaves the open market behind.

These companies range from large, well-known brands (often with a national presence) to smaller, local investors. Most will buy residential property in any condition — including those with structural issues, short leases, sitting tenants, or even properties inherited through probate. The process is designed to be as straightforward as possible, and that simplicity is what enables a remarkably fast completion.

So, How Fast Can You Actually Complete a Sale?

In theory, a quick house sale can be finalised in as little as 7 days. I’ve seen completions happen within a single working week when every star aligns — no mortgage to wait for, a cash buyer ready to go, a straightforward title, and a seller who has all their paperwork in order. However, it’s more realistic to expect a window of 2 to 4 weeks for most transactions. Some sales take slightly longer if there are legal complications or if the seller needs a bit more time to arrange a move.

Let’s break down a typical fast sale timeline:

• Day 1: You make an initial enquiry online or over the phone. Many companies respond within hours and arrange a valuation visit (or a virtual appraisal).
• Day 2–3: A representative visits your property, or you provide detailed photos and information. They assess the condition, location, and local market data. You’ll receive a formal, no-obligation offer — often within 24–48 hours of that visit.
• Day 4–7: If you accept the offer, solicitors are instructed. Because the buyer is paying cash, there’s no mortgage valuation or lender survey to slow things down. The buyer’s solicitor begins the conveyancing immediately.
• Day 7–14: Searches are ordered, contracts are drafted, and any legal queries are raised. With a cash buyer, the legal work is very stripped back compared to a traditional sale.
• Day 14–21: Once all enquiries are satisfied, you can agree on a completion date. You sign the contract, and the funds are transferred to your solicitor on the agreed day. Keys are handed over, and the sale is complete.

I must be clear: the 7-day completion is the rare exception, not the rule. Many firms advertise “sell your house in 7 days,” but that’s often based on the point at which contracts are exchanged, not the final completion of funds landing in your account. Always ask a company to clarify what they mean by “sell in X days.”

Factors That Influence the Speed of Your Sale

While the process is designed for rapid completion, several practical elements can affect exactly how quickly you get to exchange and completion:

• Your conveyancing solicitor’s efficiency: You’ll need a solicitor on your side. If they’re slow or overloaded, the whole transaction stalls. I always recommend using a solicitor who is familiar with fast-paced cash transactions.
• Legal title complexities: If there are missing deeds, a lease extension in progress, ongoing probate, or a restriction on the title, the sale will inevitably take longer. Even the most motivated cash buyer needs clean legal paperwork to proceed.
• Property condition and repairs: Most “we buy any house” companies purchase properties in their current state, so you won’t be delayed by arranging repairs. However, a property in severe disrepair might trigger additional valuation comments or a revised offer, which could reset the clock.
• Your own readiness: Can you vacate the property quickly? If you’re waiting on alternative accommodation, the completion date will need to suit your timeline. Being able to move out promptly can shave weeks off the process.
• Chain-free status of both parties: Cash buyers have no chain, and you become chain-free too if you’re not reliant on this sale to buy elsewhere. That produces the fastest possible scenario.

The Step-by-Step Process When You Use a “We Buy Any House” Service

Understanding exactly what happens at each stage helps you speed things up from your side. Here’s the expert’s roadmap:

1. Initial enquiry: Fill in a short online form or call the company. You’ll provide basic details about the property and your reason for selling.
2. Valuation and offer: A representative will visit (or conduct a remote assessment) and then present a written offer. The offer is typically below market value — often by 15–25% — to reflect the convenience, speed, and the buyer’s risk.
3. Acceptance and solicitor instruction: Once you accept, you’ll appoint a solicitor (the company may recommend one, but you have the right to choose your own). The buyer instructs theirs simultaneously.
4. Legal due diligence: Searches are run, the draft contract pack is prepared, and the buyer’s solicitor raises any enquiries. You’ll provide the property information forms and any building regulation certificates or guarantees you have.
5. Exchange of contracts: Both sides sign the contract. At this point the sale is legally binding. A completion date is set (often 1–7 days after exchange).
6. Completion: The balance of funds is transferred from the buyer’s solicitor to yours. Once the money is cleared, you release the keys. The house is sold.

With a cash buying company, there’s no mortgage offer to wait for, no survey haggling, and no chain to collapse. That’s the engine behind the speed.

Pros and Cons of a Super-Fast Sale

A “we buy any house” sale isn’t for everyone. As a friendly expert, I believe it’s only fair to lay out both sides.

Advantages:

• Certainty: Once the offer is accepted and contracts exchanged, the sale is virtually guaranteed to complete.
• Speed: As outlined, you can be out and funded in a matter of weeks — ideal for relocating, releasing equity fast, or dealing with an imminent repossession.
• No repairs or viewings: The buyer takes the property “as is”. No need to spend money on decorating or tidy up for endless viewings.
• Chain free: You avoid the dreaded property chain collapse that plagues so many traditional sales.

Potential drawbacks:

• Below market value: The biggest trade-off. You will not achieve full market price. The discount is the premium you pay for speed and convenience.
• Industry reputation: While many firms are reputable, there are some that have used high-pressure tactics or reduced offers late in the process. Always check reviews and ensure the buyer is a member of The Property Ombudsman or the National Association of Property Buyers (NAPB).
• Limited browsing time: The fast pace means you won’t have months to consider other options. Make sure the sale aligns with your broader plans.

Tips to Maximise Speed Without Sacrificing Security

If completing quickly is your top priority, here are some insider tips to keep things moving safely:

• Gather paperwork upfront: Have your title deeds (or know how to access them via the Land Registry), EPC certificate, FENSA certificates for windows, boiler service records, and any planning permissions ready to hand. That prevents solicitors’ queries from stalling.
• Choose a proactive solicitor: Don’t automatically accept the buyer’s recommended solicitor. Ask about their experience with fast cash sales and their current workload. A sluggish solicitor is the number one cause of delays.
• Ask for a guaranteed completion date: Reputable cash buyers can often commit to completing within a set timeframe, and some will even offer financial incentives if they miss that deadline. Get that in writing.
• Be transparent about the property: If you know about a subsidence claim, boundary dispute, or Japanese knotweed, disclose it immediately. Surprises mid-process cause renegotiations and delays.
• Read the offer letter carefully: Understand whether the offer is subject to survey or contract. Ideally, you want an unconditional offer once the valuation has been carried out.

Is a Same-Week Completion Right for You?

A sell house fast solution suits a specific set of circumstances. If you’re facing a divorce settlement, sudden relocation for work, repossession, an inheritance you’d rather not manage, or a property that simply won’t shift on the market, a guaranteed cash sale can remove immense stress. The ability to complete within 14–21 days (or occasionally faster) can be life-changing.

However, if you have time, it’s almost always worth testing the open market first. A traditional estate agent might get you closer to your home’s full value, even if you have to wait 8–12 weeks for a buyer and then go through the usual conveyancing rollercoaster. But when time isn’t on your side, “we buy any house” companies deliver on the promise of a speedy, certain sale.

The key is to work with a credible cash house buyer. Look for transparent pricing, membership in a recognised trade body, genuine customer testimonials, and a willingness to answer all your questions without pressure. A true expert in fast property transactions will never rush you into a decision, despite the word “fast” being in the title.

Final Thoughts

So, how fast can you actually complete a sale with a “we buy any house” company? The honest answer is: typically 2 to 4 weeks, with the absolute fastest being around 7 days if everything falls into place. The process is stripped to its essentials, and with the right preparation you can seriously accelerate it. Just remember that speed comes at a price — and that price is the discount on your home’s open-market value.

If you’re ready to move quickly and you’ve weighed up the pros and cons, don’t hesitate to reach out to a reputable cash buyer and ask them to explain their precise timeline. A friendly, no-obligation chat is often the first step toward a swift and stress-free sale.

Whether you’re selling a three-bed semi in Slough or a flat in Glasgow, there’s a fast sale option out there. The trick is finding the one that treats you fairly and keeps its promises — and that, my friend, is the real measure of a good house buyer.
