There is no such number as the correct discount. Buyers ask estate agents for one anyway — is it 5%? 10%? — because a single figure feels safer than judgement. It isn’t. Two buyers can offer the same 8% below asking on the same street and get completely different receptions, because the asking price itself was never a neutral starting point. On one house it was set carefully against recent sold prices. On the house next door it was set to see what the market would tolerate. Treating both the same way is how sensible buyers lose houses they could have had, and overpay for houses they didn’t need to.
The useful question isn’t “what percentage should I offer?” It’s “what does this asking price actually represent, and what does the seller need from a sale?” Answer those two things and the number tends to suggest itself.
Start with what the asking price is measuring
An asking price can be evidence-based or aspirational, and a buyer needs to work out which before doing anything else. Ask the agent what comparable sold prices — not other asking prices — support the figure. In England and Wales, HM Land Registry’s Price Paid Data is public and free to search and shows what properties actually changed hands for rather than what other sellers hoped to achieve.
Use it with some care. Very recent transactions may not yet appear because completed sales still have to reach the register, and a property on the same road isn’t automatically a useful comparable just because it has the same number of bedrooms. Plot size, extensions, parking, condition, tenure and even position within a street can materially change value. The strongest evidence comes from genuinely similar properties sold reasonably recently, with some allowance for anything that has happened in the local market since.
If three close comparables support a figure materially below the asking price on the house you’re viewing, that’s useful evidence that the asking price may be ambitious and a lower opening offer is entirely reasonable. If the asking price sits close to recent comparable sales, a large opening discount is more likely to be treated simply as a low offer rather than a reasoned valuation.
For Scotland and Northern Ireland, the official sold-price systems are different; GOV.UK’s house-price search service points buyers to the relevant national sources.
Two other clues matter alongside the comparables: how long the property has been listed, and whether the price has already been reduced. Time on the market doesn’t prove a seller is desperate, and a reduction doesn’t automatically mean another one is available, but both tell you something about how the original price has performed against actual buyer demand. A house that has attracted immediate serious interest at a well-supported price presents a very different negotiation from one that has sat unsold for months after already being reduced.
The seller’s position matters as much as the price
Sellers rarely respond only to the number. They respond to the number attached to a buyer they believe can actually get them to completion. This is where many buyers underestimate their own negotiating position, or overestimate it.
A seller who has already found somewhere to buy and needs their chain to move may value a proceedable buyer — one with a mortgage agreement in principle, no property to sell, or a sale already agreed — above a slightly higher offer from somebody whose own position is uncertain. A cash buyer, first-time buyer or genuinely chain-free buyer can therefore have a negotiating advantage, particularly where timing matters.
Government homebuying guidance specifically recommends making the buyer’s position clear when an offer is made, including whether finance is arranged in principle and whether there is a property to sell. GOV.UK guide to buying a home
That advantage shouldn’t be given an imaginary cash value. There is no sensible rule that being chain-free makes an offer worth £5,000 more or that a cash buyer can automatically demand another 3% off. Some sellers care primarily about price; others care deeply about certainty or timing.
The reverse is also true. A buyer who still needs to sell their own property and hasn’t arranged mortgage finance presents more uncertainty, however genuine their interest. Where that’s the position, a heavily discounted opening offer may simply give the seller little reason to take the buyer seriously unless there is strong evidence behind the number.
Property condition and marketability change the calculation
A well-presented, move-in-ready home in decent condition, priced sensibly against comparables and attracting several interested buyers is not an obvious place for an ambitious discount. Pushing too hard risks losing it to someone prepared to offer closer to what the evidence already supports.
A property requiring substantial work is different, but condition shouldn’t automatically be converted pound-for-pound into a discount. If a tired house is already listed materially below renovated examples nearby, the condition may already be reflected in the asking price. Replacing a £20,000 kitchen doesn’t automatically justify offering another £20,000 below a price that already allowed for the old one.
The more useful comparison is what similar homes in similar condition have sold for and what this particular property genuinely needs.
There is also an important distinction between work you knew about when making the offer and new information discovered afterwards. An obviously dated bathroom was visible at the viewing and belongs in the original judgement. Significant structural movement, roof problems or another material defect identified by a survey is new evidence and can legitimately reopen the discussion about price.
In England and Wales, an accepted offer is not legally binding before exchange of contracts, and official guidance recognises that significant survey findings can lead a buyer to renegotiate. GOV.UK guidance on making an offer
Unusual properties deserve particular care. A period conversion, non-standard construction, exceptionally large plot or anything genuinely unlike neighbouring homes will have thinner comparable evidence, which cuts both ways: the seller has less objective support for a precise asking price, and the buyer has less support for a precise discount. A first offer in that situation is more naturally an opening position in a conversation than a number supposedly produced by data that doesn’t really exist.
Properties marketed as “offers over” or “guide price”
These descriptions need reading in context rather than treated as formulas.
On ordinary residential listings in England and Wales, “guide price”, “offers over” and similar wording signal the seller’s intended positioning but do not prevent a buyer from offering less. What matters is how the property has actually been priced against comparable evidence and how much competition exists.
Scotland is different enough that the same rule shouldn’t simply be carried across the border. Homes are commonly marketed using “offers over” language, while the Home Report provides a professional valuation and buyers may submit formal offers through solicitors, sometimes against a closing date where several parties have noted interest. The seller isn’t required simply to accept the highest offer, but the process is sufficiently different that asking “what percentage below the offers-over figure should I bid?” can start from the wrong reference point. mygov.scot guidance on buying a home
For a Scottish purchase, the Home Report valuation, level of competing interest, mortgage position and advice from the buyer’s solicitor are generally more useful than importing an England-style negotiating percentage.
When asking price, or slightly above, is the sensible offer
It runs against instinct, but offering the full asking price — or in a genuinely competitive situation, somewhat above it — can be the rational choice rather than a failure of negotiation. Where comparable evidence supports the price, where the property has attracted serious competition and where the buyer would genuinely regret losing it for a relatively small difference, chasing a discount for its own sake can become self-defeating.
Negotiation is a means to secure the right property on reasonable terms, not an end in itself.
The discipline that matters is deciding your own ceiling before the negotiation gathers momentum. Work out what the property is worth to you, taking account of the evidence, your finances and what else you could buy, and identify the point at which you would rather walk away. That makes it much harder for a considered opening offer to turn into a succession of small increases simply because each extra £2,000 feels insignificant compared with the total price of a house.
There is another practical limit for a mortgaged buyer. The seller accepting an offer doesn’t mean the mortgage lender will necessarily value the property at the same figure. The lender will carry out its own valuation before finalising the mortgage, and a lower valuation can reduce the amount it is prepared to lend. MoneyHelper guidance on mortgage valuations
That matters particularly when bidding substantially above strong comparable evidence. A buyer may be perfectly willing to pay the extra amount, but if the lender doesn’t share that valuation the difference may have to come from the buyer’s own funds or the price may need to be renegotiated.
Offering above asking is therefore not inherently wrong. It simply shouldn’t be confused with proof that the property is worth that amount to everybody else involved in the transaction.
A worked illustration
Say a house is listed at £340,000. Two genuinely comparable homes on the same street, similar in size and condition, sold within the previous eight months for £318,000 and £322,000. The wider local market hasn’t moved enough since those sales to make them obviously outdated. The property has been marketed for eleven weeks without a reduction, the seller has no onward chain, and the buyer is proceedable with a mortgage agreement in principle already arranged.
An opening offer somewhere around £310,000 to £315,000 could be a defensible starting position. It sits below the closest comparable evidence rather than plucking a percentage from the air; the period already spent on the market gives some reason to test the seller’s willingness to negotiate; and the buyer can make their proceedable position part of the offer.
That doesn’t make £315,000 the correct value. The seller may reject it immediately. Another buyer may appear at £330,000. The seller may simply have decided that less than £335,000 isn’t enough to move.
The purpose of the example is the reasoning, not the percentage. £315,000 happens to be about 7% below £340,000, but 7% isn’t why the offer makes sense. Change the comparable sales, condition, competition or seller’s position and exactly the same percentage could be completely wrong.
The strongest offer isn’t always the highest one
An offer is a package, not just a figure. A seller weighing two reasonably close offers may prefer the buyer with no chain, finance already organised and flexibility over timing to somebody offering slightly more but presenting considerably more uncertainty.
Official guidance to sellers makes the same point: when considering offers, the seller can take account of the buyer’s financing and chain position rather than looking at price alone. GOV.UK guidance for sellers
Where the buyer’s position is genuinely strong, make it clear alongside the number. The offer can state that the buyer is chain-free or has already sold, that a mortgage agreement in principle is in place, and that there is flexibility on completion if that genuinely helps the seller.
What isn’t useful is dressing uncertainty up as strength. A mortgage agreement in principle is not a final mortgage offer, and being a cash buyer doesn’t make an unreasonable price automatically attractive.
None of this replaces the mortgage valuation or survey, both of which can alter the picture after an offer has been accepted. The lender is deciding whether it is comfortable lending against the property; the surveyor is assessing condition for the buyer. Either can introduce information that wasn’t available when the opening offer was made.
Offer strategy is therefore about starting the negotiation credibly, knowing the evidence behind the number and knowing where your own limit sits.
The right offer isn’t the biggest discount you can persuade a seller to entertain.
It’s the lowest price that has a realistic chance of securing a property you would still be happy to own at the price you eventually agree.
This article provides general information about making and negotiating offers on residential property and is not valuation, mortgage or legal advice. The homebuying process differs across the UK, particularly in Scotland, and local market conditions can materially affect negotiation. Buyers should base offers on their own finances, comparable evidence and appropriate professional advice.
