How Much Should I Offer on a House? Is the Asking Price Fair?
Published 25 October 2026
There is no fixed percentage to offer below asking. Judge whether the asking price is fair using recent sold prices, the property's own history, its condition and your budget.
"How much below asking price should I offer?" Sounds like a question that ought to have a simple percentage answer. It does not. The asking price, recent comparable sales, the property's own history and the buyer's financial limit can point in different directions. A fixed discount ignores most of that information.
The useful question is not "What percentage should come off?" It is "What price can the available evidence support?"
Short answer: to judge whether an asking price is fair, compare it with recent sold prices of genuinely similar homes nearby, check the property's own sale history, allow for its condition, tenure and size, and then test the price against what you can afford. If the asking price sits well above that evidence, the gap is something to question before you offer.
Use the free checklist before making an offer to keep track of these checks.
Thinking about buying a property?
BeforeYouBuy.house brings together property, price, energy, environmental and local information in one property report, helping you research a property before making an offer.
How to judge whether an asking price is fair
Work through these questions in order. None of them settles the price on its own, but together they show whether the asking price is supported by evidence.
- What have similar homes sold for recently? Find completed sales of comparable properties on the same or nearby streets. Asking prices of other listings are not sold prices.
- What did this property last sell for, and when? See how to find a house's sold-price history. Allow for the time since that sale and any changes to the property.
- Is the home really like the comparables? Size, number of bedrooms, garden, parking, condition and tenure all matter. A leasehold flat with ongoing charges is not directly comparable with a freehold house.
- Has the asking price already changed? A reduction or a long time on the market can tell you how buyers have responded so far, though not the reason.
- What work does the property need? Repairs, upgrades or a low energy rating can affect what the home is worth to you. A survey can help confirm condition.
- What does the price mean for your finances? Check the deposit, mortgage, monthly payment and purchase tax at the price you are considering.
If several answers point below the asking price, that is a reason to ask the agent how the price was set and to base your offer on the evidence you have gathered.
1. Treat the asking price as a starting point
The asking price is the seller's marketed price. It is not a completed transaction.
GOV.UK's home-buying guidance says buyers can make an offer once they have decided on a property, usually through the estate agent, and identifies the property's value as something to check before offering.
That distinction matters. Researching the property before deciding on an offer avoids starting with the asking price and working backwards by an arbitrary percentage.
2. Build a range from comparable sold prices
Recent sold prices are usually a stronger reference point than a general national headline. For properties in England and Wales, HM Land Registry provides registered sold-price information.
A useful comparable usually matches the property on several dimensions:
- Location
- Property type
- Approximate size
- Tenure
- Sale date
There will rarely be an identical transaction. The aim is to build a reasonable evidence range and understand why the property being considered might sit towards the top, middle or bottom of it.
3. Check the property's own sale history
The property's previous transaction history can provide another anchor. An older sale is not today's value, but it can show how much the current asking price differs from the last registered transaction.
The UK House Price Index can add broader market context because it tracks changes in residential property values using completed transaction data.
That still does not justify simply applying a regional growth percentage to an old sale and declaring the result to be the property's current value. Comparables remain important.
4. Separate "fair price" from "maximum affordable price"
Two numbers can easily become confused. One is the price that appears supportable from the property evidence. The other is the highest price that fits the buyer's finances. They are not necessarily the same. Mortgage size, deposit, transaction tax and monthly repayment can all move when the offer price moves.
BeforeYouBuy.house includes a stamp duty estimator and mortgage comparison so an offer can be tested against the financing assumptions being considered. That helps prevent an offer decision becoming detached from the monthly cost it creates.
5. Do not let one data point decide the offer
A low previous sale price does not prove the current asking price is excessive. A high nearby sale does not prove it is justified. A favourable automated estimate does not guarantee a lender, surveyor or future buyer will agree.
A stronger view combines several pieces of evidence:
- Previous sold price
- Recent comparable sales
- Property characteristics
- Local market movement
- Financial affordability
The aim is not false precision. It is a price decision with a clearer factual basis.
6. The offer process differs across the UK
The legal significance of an offer depends on where the property is. In England and Wales, GOV.UK states that an offer is not legally binding until contracts are exchanged. Scotland uses a different process. mygov.scot explains that formal offers are sent through a solicitor and that a binding contract is formed when the missives are concluded.
The legal process and any conditions attached to an offer are therefore separate from the question of what price the evidence supports.
Before you make an offer, know what you're buying.
Don't spend hours jumping between different websites trying to piece together the information yourself. Search for a property and get the information in one report.
Turn the asking price into an evidence-based decision
Start with comparable transactions
Look for a range of similar properties rather than searching for one perfect match.
Add the property's own history
Previous transactions and broader local market movement can explain where today's asking price sits.
Financial planning, built in
BeforeYouBuy.house places the mortgage, stamp duty and value scenarios alongside the property research, so the potential offer and the financial consequences can be considered together.
This article is for general information only and is not financial, valuation or legal advice. The legal effect of an offer and the property-buying process vary across the UK, and individual circumstances may require professional advice.
Before you buy, do your research
An offer is a number. The reasoning behind it matters more.
What have similar properties actually sold for?
How does the asking price compare with the property's own history?
What happens to the mortgage and purchase costs at the price being considered?
These are questions worth answering before you commit to one of the biggest purchases you'll ever make.
