Key Takeaways
- Legitimate house buying companies typically offer 75-85% of market value for a fast cash sale
- The discount covers stamp duty (5% surcharge), refurbishment, capital gains tax, holding costs, and resale fees
- Any company offering 85-100% of market value for a “quick cash sale” is almost certainly not genuine
- When you factor in estate agent fees (~1.42%), solicitor costs, mortgage payments during the sale, and the risk of chain collapse (around 24% of sales fall through), the net gap between a cash offer and a traditional sale is often smaller than it first appears
- A cash sale makes the most financial sense when speed, certainty, or a problem property limits your options on the open market
Nearly one in four agreed house sales in the UK falls through before completion.
That statistic, from early 2026 data, is the reason house buying companies exist. Speed and certainty have real value when the traditional route is slow, expensive, and far from guaranteed.
But here’s the question I get asked more than any other: how much below market value will you actually offer?
The honest answer is that reputable cash buying companies offer 75-85% of your property’s open market value. That’s a discount of 15-25%.
In this guide, I’ll explain exactly why that discount exists, what it covers, how to spot the scam operators promising you “100% of market value”, and when a cash sale genuinely makes financial sense.
What Is Market Value (And Why It’s Not What You’ll Actually Receive)?
Before we get into the numbers, let’s clear something up.
“Market value” sounds like a fixed number. It isn’t.
Market value is the price your property would likely achieve if you listed it with an estate agent, marketed it properly, found a willing buyer, and completed the sale without any complications. It’s based on recent comparable sales in your area, the condition of your property, and current demand.
But here’s the thing most sellers overlook: market value is not the same as what you take home.
By the time you’ve paid your estate agent (average 1.42% including VAT in 2026, according to the HomeOwners Alliance), your solicitor (typically £750-£1,500 for a sale), your EPC certificate, and any repairs or staging needed to make the property sellable, you’re already 3-5% below the headline figure.
Then factor in the mortgage payments you’ll continue making during the 5-6 months it takes to sell on average (Pine, 2026), and the picture shifts further.
The “market value” on your estate agent’s brochure is a starting point, not a final figure. Your net proceeds are always lower.
The Realistic Range: 75-85% of Market Value
So, what do genuine house buying companies actually offer?
Most reputable firms offer between 75% and 85% of market value for a fast cash purchase. That’s the industry standard, and it’s been broadly consistent for years.
The exact percentage depends on several factors.
What Affects the Offer?
- Property type. Houses generally attract higher offers than flats. Why? Houses are easier to sell, have broader buyer appeal, and don’t carry the leasehold complications that flats typically do.
- Location. Properties in high-demand areas with strong resale markets may push towards 85%. Properties in areas with oversupply or lower demand will sit nearer 75%.
- Condition. A property that’s ready to market immediately commands a higher offer than one needing structural work, damp treatment, or a new roof.
- Market conditions. In a rising market, offers tend to be firmer. In a flat or falling market (like much of England in 2026, where prices are down 0.6% year-on-year per HM Land Registry, March 2026), the risk premium increases.
- Speed required. A 7-day completion carries more risk for the buyer than a 28-day one, which can affect the offer.
Houses vs Flats: Why There’s a Difference
You’ll often see a gap of around 5% between offers on houses and flats. There are good reasons for that.
Flats have been harder to sell since COVID. The shift to remote and hybrid working pushed buyer demand towards houses with gardens and outdoor space. That trend hasn’t reversed. In some areas, flats are sitting on the market for months with dozens of competing listings in the same postcode.
Higher transaction costs. Flats are almost always leasehold, which means management packs, leasehold supplements on conveyancing fees, and longer legal timelines. Those costs come out of the buyer’s margin.
Longer resale times. Rightmove data consistently shows flats taking significantly longer to sell than detached or semi-detached houses. That means more council tax, more insurance, and more holding risk before the cash buyer sees any return.
Did You Know?
Flat oversupply is a real issue in some areas. In certain postcodes, you can find over 100 flats competing for buyers within a quarter of a single postcode area. That level of competition drives down prices and lengthens time on the market.
Why Do House Buying Companies Offer Below Market Value?
This is the bit that frustrates people. “Why can’t they just pay full price?”
Short answer: because full price for a cash buyer is a guaranteed loss.
House buying companies aren’t charities. They’re businesses that buy your property, absorb all the costs and risks, and then try to sell it for a profit. The discount between what they pay you and what they eventually sell for has to cover a long list of expenses that most sellers never think about.
The Costs a Cash Buyer Absorbs on Every Deal
Let me walk you through a typical purchase on a £275,000 house.
| Cost | Amount | Notes |
|---|---|---|
| Stamp duty (SDLT) | £16,250+ | 5% surcharge on additional properties (increased from 3% in Oct 2024) |
| Solicitor fees (both sides) | £2,000-£3,000 | Many companies cover the seller’s legal fees too |
| Refurbishment | £5,000-£30,000+ | Properties bought as-is often need work before resale |
| Estate agent fees on resale | £3,900-£5,000 | 1.42% average inc. VAT (2026) |
| Capital Gains Tax | 24% of profit | Higher rate, not the basic rate. Annual allowance just £3,000 |
| Council tax | £150-£300/month | Payable from completion until resale |
| Insurance and utilities | £100-£200/month | Building insurance, security, utilities during holding period |
Add those up and you’re looking at £30,000-£60,000+ in costs on a single £275,000 property before the company makes a penny.
The margins are genuinely tight. A cash buyer offering you 80% of market value isn’t pocketing the other 20%. Most of it goes straight out again in costs and taxes.
Risk Transfer: What You’re Really Paying For
Beyond the hard costs, there’s the risk.
When you sell to a cash buying company, you’re transferring a bundle of risks that would otherwise sit with you.
- Market risk. The company owns the property through whatever happens next in the market. Prices could fall. They absorb that.
- Chain risk. Around 24% of traditional sales fall through before completion. The cash buyer removes that possibility entirely.
- Condition risk. They buy as-is. No demands for repairs. No renegotiation after the survey. Whatever issues exist become their problem.
- Time risk. The average UK house sale takes 5-6 months from listing to completion. During that time, you’re paying your mortgage, council tax, and insurance. A cash buyer completes in weeks.
The discount isn’t a penalty. It’s the price of certainty.
What “Market Value” Actually Costs You on the Open Market
Here’s where things get interesting.
Most people compare a cash offer against the headline “market value” and feel short-changed. But that’s not the right comparison. You should compare the cash offer against what you’d actually take home from a traditional sale.
The True Cost of Selling Through an Estate Agent
Let’s use a £275,000 property as an example and break down the real costs of selling on the open market.
| Cost Item | Traditional Sale | Cash Buyer Sale |
|---|---|---|
| Sale price | £275,000 | £220,000 (80%) |
| Estate agent fee (1.42%) | -£3,905 | £0 |
| Solicitor/conveyancing | -£1,200 | £0 (covered by buyer) |
| EPC certificate | -£85 | £0 |
| Repairs/staging | -£2,000 (estimate) | £0 (bought as-is) |
| Mortgage payments (5 months) | -£5,500 (estimate) | -£1,100 (1 month) |
| Council tax (5 months) | -£1,000 | -£200 (1 month) |
| Net proceeds | £261,310 | £218,700 |
| As % of market value | ~95% | ~79.5% |
| Timeline | 5-6 months (average) | 2-4 weeks |
| Certainty of sale | ~76% (24% fall-through rate) | Guaranteed |
The headline gap looks like 20% (£275,000 vs £220,000). But the actual net gap is closer to 15% once you strip out the costs of a traditional sale.
And that’s assuming everything goes smoothly. If your buyer pulls out three months in, you’re back to square one with wasted legal fees, wasted time, and several more months of mortgage payments ahead of you.
The Net Proceeds Reality
When open-market costs are included (agent fees, solicitor fees, repairs, and ongoing mortgage payments during the sale), net proceeds from a traditional sale often end up around 90-95% of market value. A cash offer at 80% is closer to that figure than most people realise.
What If Your Sale Falls Through?
This is where the comparison really shifts.
Around 24% of agreed sales in the UK fell through in early 2026 (ABC Money, May 2026). That’s roughly one in four.
If your sale collapses, you lose:
- Abortive legal fees (typically £500-£1,000 that you won’t recover)
- Months of mortgage and council tax payments during the failed sale and the restart
- Momentum. A property that’s been listed, pulled, and relisted carries a digital footprint. Buyers and agents notice. It can reduce the eventual sale price.
- Emotional cost. Starting over after months of hope is exhausting.
Factor in a single fall-through, and the net proceeds from a traditional sale drop significantly. Two fall-throughs (not uncommon in a chain), and a cash offer at 80% might have been the better deal from the start.
The Seven Factors That Determine Your Cash Offer
Not every property gets the same percentage. Here’s what moves the needle.
1. Property Type (House vs Flat vs Bungalow)
Houses generally attract higher offers (closer to 80-85%) because they’re easier to resell. Strong buyer demand, freehold ownership, no service charges.
Flats sit lower (around 75%) due to leasehold complexity, oversupply in many areas, and longer resale timelines.
Bungalows are interesting. They’re in high demand from downsizers and retirees, so offers can be competitive.
2. Location and Local Market
A three-bed semi in a popular school catchment area in Surrey will get a different offer to a similar property in an area with low demand and high stock.
Cash buyers assess how quickly they can resell. Hot markets mean less holding time, less risk, and often a better offer for you.
3. Condition
A well-maintained, move-in-ready property costs the buyer less to prepare for resale. That means a stronger offer.
Properties with serious issues (subsidence, Japanese knotweed, structural damp, asbestos, short leases) will attract lower offers because the refurbishment or remediation costs are deducted from the margin.
The advantage? Cash buyers still buy these properties. On the open market, many of these issues would make a property unmortgageable, meaning you’d struggle to find any buyer at all.
4. Tenure (Freehold vs Leasehold)
Freehold properties are simpler and cheaper to transact. Leasehold properties involve management packs (£200-£500), leasehold supplements on conveyancing, and potential complications with the freeholder.
Short leases (under 80 years) are a particular issue. Lease extension costs can run to tens of thousands of pounds, and this will be reflected in the offer.
5. Current Market Conditions
In a rising market, cash buyers can be more confident about resale and may offer higher percentages.
In a flat or falling market, like much of England in 2026 (HM Land Registry shows 0.0% annual growth nationally, -2.1% in London), the risk increases and offers tend to be more conservative.
6. Speed of Completion Required
A standard 28-day completion gives the buyer time for proper due diligence. A 7-day emergency completion is possible but carries more risk, which may be reflected in the offer.
7. Any Complications
Sitting tenants, legal disputes, restrictive covenants, planning issues, shared ownership structures. Each complication adds cost, time, and risk for the buyer.
That said, cash buyers are often the only option for properties with significant complications. Traditional buyers and their mortgage lenders will walk away. A cash buyer will still make an offer.
Scam Companies: How to Spot Them and Protect Yourself
Not all house buying companies are genuine. Some are outright scams. Others are legitimate businesses using practices that can cost you dearly.
Here’s what to watch for.
The “100% Market Value” Trap
Warning: Too-Good-To-Be-True Offers
If a company offers you 85-100% of market value for a quick cash sale, alarm bells should ring. It is simply not possible for a cash buying company to pay full market value, cover all its costs, and still operate as a viable business. The maths doesn’t work.
These companies typically use one of two tactics: they reduce the price at the last minute when you’re emotionally committed and vulnerable, or they’re not buying the property at all.
Here’s how the “100% market value” scam typically works.
A company promises you a price that sounds too good to be true. You sign up. They string you along for weeks, sometimes months. Then, just before completion, they drop the price. Maybe by 15%. Maybe by 25%.
By that point, you’ve already told your solicitor, made plans to move, possibly committed to buying another property. You’re vulnerable. They’re counting on you accepting the lower figure rather than walking away and starting over.
These companies have never been genuine cash buyers. Most of them operate by capturing your lead and then selling it on to legitimate quick sale companies.
The Middleman Problem
This is perhaps the more insidious practice.
Some companies portray themselves as cash buyers but are actually middlemen. They don’t have the funds to buy your property. Instead, they market it on Rightmove, Zoopla, or OnTheMarket without your knowledge or consent.
Here’s why that’s a disaster for you.
Your property sits on the portals for weeks with no strategy behind it. That leaves an electronic footprint. Estate agents and experienced buyers can see that the property has been listed, possibly at the wrong price, with poor photos, and with no viewings. The perception is that something’s wrong with the property. Its perceived value drops.
Even if you eventually take the property off those portals and sell through a genuine route, that digital history follows you. Buyers check. Agents check. A stale listing damages your price.
Meanwhile, the “cash buyer” was never buying. They were trying to flip your details to another buyer or take a cut as an introducer.
How to Vet a House Buying Company
Before you accept any offer, do your homework.
- Check for NAPB membership. The National Association of Property Buyers is the voluntary trade body for the quick house sale industry. Members agree to professional standards and sign up to The Property Ombudsman’s Code of Practice, giving you access to free dispute resolution. It’s not legally required (the sector isn’t formally regulated), but it’s one of the strongest trust signals available.
- Ask for proof of funds. A genuine cash buyer should be able to provide evidence that they have the money ready to purchase your property. If they can’t, or won’t, walk away.
- Verify their trading history. Look for companies that have been operating for years with a real office address, named directors, and a track record of completed purchases.
- Read independent reviews. Check Trustpilot, Google Reviews, and the Property Ombudsman for complaints. Look for detailed reviews from real sellers, not generic five-star entries.
- Ask the right questions. “Do you buy the property yourself, or do you pass my details to third parties?” “Will my property be marketed on any portals?” “Is your offer fixed, or could it change before completion?” The answers will tell you everything.
FCA Regulation: What You Need to Know
General house buying isn’t regulated by the FCA. However, Sale and Rent Back services (where you sell your home and then rent it back from the buyer) are FCA-regulated. If a company offers this service, check they’re on the FCA Register. If they’re not, they’re operating illegally.
When Does Selling Below Market Value Make Sense?
A quick cash sale isn’t right for everyone. I’ll be honest about that.
If you have time, your property is in good condition, and you’re not under pressure, you’ll almost certainly get more on the open market. List it with a good local estate agent and wait for the right buyer.
But there are situations where accepting 75-85% of market value is the smart move.
Facing Repossession
When your lender is threatening to repossess, every week matters. A repossession on your credit file can affect your ability to borrow for six years or more. A fast cash sale can clear the mortgage, stop the proceedings, and protect your credit rating.
Broken Chain
Your buyer pulls out two weeks before completion. Your onward purchase depends on the sale. Your sellers are threatening to walk. A cash buyer can step in and complete in weeks, saving the entire chain.
Divorce or Separation
When a relationship ends and both parties need to move on, a fast sale avoids months of shared financial entanglement. Clean. Final. Done.
Inherited Property
Inheriting a property you don’t want to keep means paying council tax, insurance, and maintenance on a second home while you try to sell it. If the property needs work, the costs pile up quickly. A cash sale stops the bleeding.
Problem Property
Structural issues. Non-standard construction. Japanese knotweed. Short lease. Subsidence history. These properties are often unmortgageable, meaning your buyer pool on the open market is limited to cash buyers anyway. Selling direct to a cash buying company removes the middleman.
Declining Market
This is the one people don’t think about.
With HM Land Registry showing London down 2.1% and England down 0.6% year-on-year (March 2026), waiting six months for a higher open-market offer is a gamble. If the market drops 3-4% during that period, you’ve lost more in value than the cash buyer’s discount.
A cash sale locks in today’s value. In a falling market, that certainty can be worth more than the extra percentage points you’re hoping for.
Relocation
A new job starts in four weeks. You need to move across the country. Selling through an estate agent takes 5-6 months on average. The maths writes itself.
A Real Case Study: When the Numbers Added Up
Let me share a real scenario where selling below market value turned out to be the right decision.
Case Study: Chain Break, Interest-Only Mortgage, Repossession Threat
We had a client who’d experienced a chain break. They owned a property on an interest-only mortgage that was about to end, and they couldn’t afford to remortgage. Repossession proceedings had already started.
The traditional route would have meant relisting, waiting months for a new buyer, paying ongoing mortgage arrears, and the real possibility of losing the property to the lender.
When we factored in the legal costs, ongoing mortgage payments, estate agent fees, and the time it would take to find another buyer on the open market, our cash offer was comparable to what the client would have netted from their previous open-market sale. The difference? We completed in 4 weeks and stopped the repossession.
Same net financial outcome. But one path avoided repossession, protected the seller’s credit rating, and removed months of uncertainty.
That’s when a cash sale makes sense. Not because it pays more, but because time and certainty have real financial value.
How to Maximise Your Cash Offer
If you’ve decided a cash sale is right for your situation, here’s how to get the best possible price.
Get Multiple Quotes
Don’t accept the first offer. Contact at least three NAPB-registered companies and compare. Make sure each one provides a formal written offer, not just a phone quote.
Know Your Property’s Value
Before you speak to any cash buyer, get your own valuation. Use two or three local estate agents for free market appraisals. Check recent sold prices on the Land Registry and Rightmove sold prices.
When you know the genuine market value, you’ll immediately spot any company offering an unrealistically high or low figure.
Be Honest About the Property
Disclose everything upfront. Structural issues, boundary disputes, planning restrictions, tenant situations. If the cash buyer discovers problems later during their survey, their offer will drop. Being transparent from the start means the initial quote is more likely to hold.
Understand What’s Included
Ask specifically:
- Do they cover your legal fees?
- Are there any admin fees, withdrawal fees, or hidden charges?
- Is the offer price fixed, or could it change after the survey?
- What’s the expected completion timeline?
Get everything in writing. A genuine company will have no problem putting it on paper.
Don’t Confuse Speed With Desperation
Just because you need to sell quickly doesn’t mean you should accept a lowball offer. A legitimate cash buyer will offer a fair price within the 75-85% range. If the offer feels significantly below that, get a second opinion.

Cash Buyer vs Estate Agent vs Auction: A Side-by-Side Comparison
Here’s how the three main routes to selling a property stack up against each other.
| Factor | Cash Buying Company | Estate Agent | Auction |
|---|---|---|---|
| Typical sale price | 75-85% of market value | 90-100% of market value | Varies widely (can be below 75%) |
| Fees you pay | None (reputable companies) | 1.42% avg + solicitor (~£5,000-£6,000) | 1.5-3% commission + entry + legal |
| Timeline | 2-4 weeks | 5-6 months (average) | 6-10 weeks (including marketing) |
| Certainty | Guaranteed (if genuine buyer) | ~76% completion rate | High once hammer falls, but no guarantee it sells |
| Property condition | Bought as-is | May need repairs/staging | Sold as-is |
| Chain risk | None | High (most sales involve chains) | None (28-day completion) |
| Privacy | No public marketing | Listed on portals, viewings | Listed in auction catalogue |
| Best for | Speed, certainty, problem properties | Maximum price (if you have time) | Unusual properties, land, commercial |
The Bottom Line
“Fair” depends entirely on your situation.
If you’ve got six months and your property is in good condition, sell on the open market. You’ll likely net more, even after agent fees and costs.
But if you need speed, certainty, or you’re dealing with a problem property, a broken chain, or a declining market, then 75-85% of market value can absolutely be the right call.
Here’s the honest truth from someone who’s been buying houses for over 20 years. A cash buyer isn’t offering you less because they’re greedy. They’re offering less because they’re taking on all the risk, cost, and time that would otherwise sit with you.
The key is knowing your options and understanding the true net cost of each one.
Frequently Asked Questions
Is it legal to sell a house below market value?
Yes, completely legal. You can sell your property for whatever price you agree with a buyer. There are no legal restrictions on selling below market value. However, if you sell to a family member significantly below market value, HMRC may treat the discount as a gift for inheritance tax purposes. When selling to a commercial buyer like a house buying company, this isn’t a concern.
What is the lowest offer you should accept on a house?
There’s no universal rule. On the open market, offers below 90% of the asking price are generally considered low. From a cash buying company, anything below 70% of independently verified market value should raise concerns. Reputable companies offer 75-85%. If you’re offered less than 70%, get a second opinion.
Do cash buyers always offer below market value?
Yes. Every genuine cash buying company offers below market value because they need to cover stamp duty (with a 5% surcharge on additional properties), refurbishment, resale costs, capital gains tax, and holding costs. If someone claims to be a cash buyer offering 100% of market value, they are almost certainly not a genuine buyer.
How quickly can a house buying company complete?
Most reputable companies complete in 2-4 weeks. Some can complete in as little as 7 days in emergency situations (such as imminent repossession). The average is around 28 days. Compare that to the 5-6 month average for a traditional estate agent sale.
Do I have to pay any fees when selling to a house buying company?
Reputable companies charge no fees. Many also cover your solicitor’s fees if you use their recommended conveyancer. Watch out for companies that charge “admin fees”, “withdrawal fees”, or “marketing fees”. These are red flags. A genuine cash buyer makes their money on the resale, not by charging you.
Can I negotiate with a house buying company?
You can try, but the margins are genuinely tight. Most companies have already calculated their maximum offer based on market value, costs, and resale potential. There’s usually limited room for negotiation. Your best strategy is to get quotes from multiple companies and compare.
What happens if the cash buyer’s survey finds problems?
If the survey reveals issues that weren’t disclosed upfront (structural problems, damp, subsidence history), the buyer may adjust their offer. This is why transparency matters. Disclose everything from the start, and the formal offer is far more likely to match the initial quote.
Are house buying companies regulated?
The quick house sale industry is not formally regulated by the FCA (except for Sale and Rent Back services). However, the NAPB (National Association of Property Buyers) operates as a voluntary trade body with professional standards. All NAPB members must be registered with The Property Ombudsman, which gives sellers access to a free complaints and dispute resolution service. Always check for NAPB membership before proceeding.
Will selling below market value affect my mortgage?
You can sell at any price, but you must repay the full outstanding mortgage balance from the sale proceeds. If the sale price is less than the remaining mortgage (negative equity), you’ll need your lender’s consent to the sale and an agreement to handle the shortfall. Speak to your lender or a mortgage adviser before proceeding.
Is a house buying company better than an auction?
It depends on your priorities. Auctions can sometimes achieve higher prices, especially for unusual properties, but there’s no guarantee your property will sell. You also face auction fees (1.5-3% commission plus entry and legal costs), and the process takes 6-10 weeks including marketing. A cash buying company offers a guaranteed sale at a known price, typically within 2-4 weeks.
Ready for a No-Obligation Cash Offer?
