Buying Property
Things to Check Before Buying a Property
Published 17 August 2026 · Updated 13 September 2026
Buying a property is one of the biggest financial decisions you're likely to make. Before making an offer, there are a number of things worth checking — from previous sale prices and property value to EPC ratings, flood risk, location and ongoing costs.
Buying a property is a huge financial decision. Yet when you find a property you like, much of the information you need to decide whether it's actually a good purchase is scattered across different websites.
You might find the property's previous sale price on one website, its EPC somewhere else, flood information on another, and local property data somewhere else again. Before you make an offer, it's worth bringing all of this information together.
This guide explains the key information worth checking about a property before buying it — and how BeforeYouBuy.house can help.
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.
1. What did the property previously sell for?
One of the first things worth checking is the property's sale history. If a property is currently listed for £450,000, it is useful to know what someone previously paid for it. For example, a property that is currently asking £450,000 may have previously sold for £320,000 in 2019.
That doesn't necessarily mean the property is overpriced. It may have been renovated, extended or otherwise improved since then. But it gives you important context.
You can then ask: how much has the property increased in value? How long ago was the previous sale? How does that increase compare with other properties in the area? Does the current asking price make sense?
BeforeYouBuy.house makes this information easier to investigate as part of a property report.
2. How does the asking price compare with similar properties?
The asking price alone doesn't tell you whether you're getting a good deal.
One of the most useful things you can do is compare the property with recently sold properties nearby. For example, if you're considering a £500,000 house and similar properties nearby recently sold for £465,000, £475,000, £480,000 and £510,000, the asking price suddenly has much more context.
You can also look at factors such as property type, number of bedrooms, size, location, recent sale prices and price per square metre.
This is much more useful than simply looking at other properties currently listed for sale. Properties listed at £500,000 aren't necessarily worth £500,000 — the prices that buyers have actually paid can tell you much more.
BeforeYouBuy.house brings property and local price information together so you can assess the asking price in context.
3. How has the property's price changed?
A property's current asking price is only one point in its history.
Its previous transactions can help you understand how its value has changed over time. For example:
2017: £285,000 → 2021: £355,000 → 2026 asking price: £450,000
That immediately raises some questions. Is the latest increase consistent with the local market? Has the property been substantially improved? Is the asking price ambitious? You don't necessarily need to answer these questions with certainty. The important thing is having the information available before you decide what you're prepared to pay.
4. What is the property's energy efficiency like?
An EPC can tell you considerably more than simply whether a property has an A, B or C rating. You can look at the current EPC rating, potential rating, estimated energy costs, heating, insulation, windows and recommended improvements.
This can be particularly useful when comparing two otherwise similar properties. For example, one property might have an EPC rating of C with estimated energy costs of £1,500 per year, while another has an E rating and estimated costs of £2,300.
The difference isn't necessarily a reason to reject the second property, but it is something you should know before making an offer.
BeforeYouBuy.house includes EPC information in its property reports.
5. Is the property at risk of flooding?
Flood risk is another piece of information that isn't necessarily obvious from a property listing.
A property can look completely normal during a viewing while still being located in an area with potential flood risk. Depending on the location, relevant information can include river flooding, surface-water flooding, coastal flooding and other environmental information.
This is important because environmental risks can potentially affect insurance, future resale, your willingness to buy the property and the price you're prepared to pay. Environmental data also needs to be interpreted carefully. A risk indicator doesn't mean a property will definitely flood, and the absence of an indicator doesn't guarantee that it never will.
The point is simply to know about potential risks before committing to the purchase.
BeforeYouBuy.house brings environmental information into the same report as the property's other data.
6. What is the area around the property like?
You're not only buying the property. You're buying its location. The quality of the surrounding area can have a major impact on both your experience of living there and the property's future value. When researching an area, you might want to understand things such as local population, demographics, employment, deprivation, property prices and local market characteristics.
This can be particularly useful when you're considering a location you don't know well. A property might look like a bargain until you discover that comparable properties in nearby areas are selling for similar prices. Equally, you might discover that an area you've overlooked offers considerably better value than you expected.
BeforeYouBuy.house brings local information together with property and price data, giving you a broader picture of the area you're considering.
7. How does this property compare with the local market?
It's easy to become focused on a single property. You've seen it. You like it. You can imagine living there. And suddenly £450,000 feels like the price of the house, rather than simply the seller's asking price. That's why stepping back and looking at the wider market is useful.
You can investigate recent transactions, local property prices, property types, price trends and comparable properties. The aim isn't to produce a perfect valuation. It's to give you more information before deciding how much you're willing to pay.
A property report can help you look at the property in the context of the wider market rather than making a decision based purely on the estate agent's asking price.
8. The problem: property information is scattered
This is perhaps the biggest problem when researching a property yourself.
The information exists — but it is fragmented. You might start with the estate agent listing, then search for the property's previous sale, find its EPC, look up flood information, investigate the local area and search for nearby transactions.
By the time you've finished, you've potentially spent hours researching one property — and you still have to work out what all the information means.
That's the problem BeforeYouBuy.house is designed to solve.
Research a property in one place
Instead of jumping between different websites, BeforeYouBuy.house brings key property information together in one report.
Enter the property you're considering and get information covering areas such as:
Property
Key information about the property and address.
Property prices
Previous sale information and local property data to help put the asking price into context.
Energy
EPC information and energy-efficiency data.
Environmental
Relevant environmental and flood-risk information.
Location
Data about the area surrounding the property.
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.
What BeforeYouBuy.house doesn't replace
A property report isn't intended to replace a professional survey, conveyancing or other professional advice. Instead, it gives you useful information before you get to that stage.
The idea is simple: research the property first, decide whether it's worth pursuing, and then move forward with the next stage of the buying process.
Before you buy, do your research
A property can look perfect in a listing. The asking price can look reasonable. And you can fall in love with it after one viewing. But before making an offer, it's worth taking a step back and looking at the data.
What did it sell for? How does the price compare with similar properties? How energy efficient is it? Are there environmental risks? What does the surrounding area look like? Does the asking price make sense in context?
These are questions worth answering before you commit to one of the biggest purchases you'll ever make.
BeforeYouBuy.house brings the research together.
