The 80% trade-off explained

What market value really means
The only true way to know a property’s market value is to place it on the open market and allow buyers to compete.
Until that happens:
valuations are opinions
asking prices are expectations
even comparables are estimates
Market value is not confirmed until a buyer commits and completes.
Cash buying companies understand this. They are not pricing against a guaranteed figure — they are pricing against what they hope the property might sell for, under normal market conditions, at a future point in time.
Where the 80% figure actually comes from
In practice, many genuine cash buyers aim to pay around 80% of their expected resale value, not 80% of an agent’s valuation.
This reflects a simple economic trade-off:
Instead of paying 1–2% to an estate agent for an uncertain outcome, the seller is effectively paying a higher premium for certainty, speed, and risk transfer.
Seen this way, the discount is not arbitrary. It is the price of removing market risk, buyer fall-through risk, time delays, and chain dependency.
The seller is not accepting less “because it is a cash offer” — they are paying for certainty.

Certainty carries a premium — for both sides
From the seller’s perspective, the trade-off is giving up upside potential in exchange for a fixed, predictable outcome.
From the buyer’s perspective, capital is deployed immediately, risk is absorbed upfront, and costs begin accruing from day one.
This is why the comparison with estate agency fees is misleading. The services — and the risks — are not the same.
What happens after a cash buyer completes
Once a genuine cash buyer has purchased a property, they carry the full exposure of resale.
From real transaction data, it is not uncommon for around 1 in 10 properties to sell for significantly less than expected. Some resell at the same price they were purchased for.
In those cases, the original seller effectively achieved 100% market value, while the buyer absorbs stamp duty, legal fees, holding costs, finance costs, and sales fees.
These losses can be substantial — and they are an unavoidable part of genuine cash buying. This is why realistic pricing matters.
Why 80% is not a rule — and often not accurate
Many completed fast sales do not sit neatly at 80%.
Some complete at higher percentages where condition is strong and urgency is low. Others complete at lower percentages where complexity, risk, or speed requirements are high.
The percentage reflects risk distribution, not a fixed deduction.
Why claims of “90% of value” should raise questions
From experience, no genuine cash buying company consistently pays 90% of market value.
When offers are presented this way, it is often because the company is not intending to complete itself. Instead, an option agreement may be used and the property may be marketed to find another buyer.
In effect, the seller is paying around 10% for an estate agency-style service — for a role that could typically cost 1–2% on the open market.
The risk profile — and the service being provided — is fundamentally different.

The key distinction sellers should understand
A genuine cash buyer:
prices in risk
uses its own capital
accepts that some deals will underperform
aims to complete at the agreed price
An option-led operator:
minimises its own risk
relies on onward buyers
uses the seller’s commitment as leverage
is more exposed to price changes
Understanding which model is being used matters more than the headline percentage.
Questions to ask if a percentage is mentioned
If a buyer references “80%” or “90%”, it is reasonable to ask:
What resale value is this based on?
Is this price conditional on finding another buyer?
Will I be asked to sign an option agreement?
What risks are you taking on directly?
What would cause the price to change?
Clear answers reveal the true nature of the offer.
Rule of thumb
Market value is only proven on the open market.
A genuine cash offer reflects the cost of certainty — not a shortcut to a higher price.
Your next step
You now know how the trade-off between price and certainty actually works. If you want to see your side of it in numbers, our offer tool shows a realistic range based on how genuine cash buyers actually price properties — typically 75–85% of open-market value — built on observed pricing behaviour, not marketing claims.
Step 1 is free and anonymous — no name, phone number or email, just basic property details. Step 2 is entirely optional — if the range works for you, you can ask to be introduced to a cash buyer we have vetted. Your details are never shared unless you ask, and never sold.
