Is This Property Good Value? How to Tell

Asking prices are aspirations, not valuations. Vendors and agents set them based on what they hope to achieve, not necessarily what the market will bear. Your job as a buyer is to separate realistic pricing from optimism.

Here's how to assess whether a property represents fair value, using the same methods professionals use. Combined with reading property listings carefully, this will give you confidence in your valuations.

How to Assess Value

Property valuation isn't precise. Two qualified surveyors can look at the same house and arrive at figures 10% apart. But there are objective indicators that help you understand whether an asking price is realistic.

Comparable Sales Approach

The most reliable method is comparing to recent sales of similar properties. What did comparable homes actually sell for, not what they asked?

Finding comparables:

1. Search the Land Registry Price Paid Data for your target postcode
2. Filter for sales in the last 12-18 months
3. Look for similar property types (flat vs house, beds, approximate size)
4. Adjust for obvious differences (garden vs no garden, condition, floor level)

The closer your comparables, the more useful they are. Same street is better than same postcode. Same building is ideal for flats.

Price Per Square Foot

Price per square foot (or square metre) allows comparison across different-sized properties. It's particularly useful when comparing properties that aren't direct matches.

Calculation: Asking price ÷ square footage = price per sqft

A £350,000 flat of 750 sqft = £467 per sqft A £400,000 flat of 900 sqft = £444 per sqft

The larger flat is better value per square foot, even though it costs more overall.

UK averages by area type:

• Prime London: £1,000-£2,000+ per sqft
• Greater London: £400-£800 per sqft
• Major cities: £250-£500 per sqft
• Suburbs and commuter towns: £200-£400 per sqft
• Rural areas: £150-£300 per sqft

These are rough ranges. Your specific area will have its own norms. Check sold prices with square footage in your target location to establish local benchmarks.

Time on Market Signals

How long a property has been listed tells you something about its pricing.

Fresh listings (0-4 weeks): No conclusions yet. The market hasn't had time to respond.

Standard duration (4-12 weeks): Normal timeline in most markets. Some properties take time to find the right buyer.

Extended listing (12+ weeks): Either overpriced, has issues, or both. Investigate which.

Asking vs Sold Prices

In most of the UK, properties sell below asking price. The gap varies by market conditions:

Hot markets: Properties might sell at or above asking Normal markets: 3-5% below asking is typical Slow markets: 5-10% or more below asking

Research your specific area. Some neighbourhoods are more competitive than others.

Finding Comparable Sales

Good comparables share key characteristics with your target property.

Same Street or Building

The gold standard. Properties on the same street share location factors. Flats in the same building share service charges, lease terms, and condition.

Similar Property Type

Compare flats to flats, terraced houses to terraced houses. A three-bed terraced house isn't comparable to a three-bed detached, even in the same postcode.

Recent Sales

Prioritise sales from the last 12 months. Property markets change. A sale from three years ago reflects different conditions.

Adjustment Factors

Perfect comparables rarely exist. Account for differences:

• Condition: Recently renovated vs needs work
• Size: Similar bed count but different sqft
• Features: Garden, parking, period details
• Floor level: Ground floor flat vs top floor (usually premium)
• Aspect: South-facing garden vs north-facing

A comparable that sold for £300,000 but was smaller and needed work might suggest your target (larger, renovated) is worth £330,000-£350,000.

Price Per Square Foot Analysis

How to Calculate

You need the square footage, which isn't always provided. If missing, request it from the agent or estimate from the floor plan.

The formula: Price ÷ Square feet = Price per sqft

When It's Useful

Price per sqft works well for:

• Comparing similar properties of different sizes
• Understanding area pricing norms
• Identifying outliers (very cheap or expensive for the sqft)
• Quick screening of listings

When It's Misleading

Price per sqft has limitations:

Premium features don't scale: A garden, parking space, or exceptional view adds value but not square footage. Two identical-size flats where one has a terrace shouldn't have the same price per sqft.

Usable vs total space: Awkward layouts reduce effective space. A 1,000 sqft flat with a long corridor is worth less than a 950 sqft flat with efficient layout.

Location within building: Top floor with views vs ground floor facing bins. Same sqft, different values.

Use price per sqft as one data point, not the definitive answer.

Time on Market Analysis

Fresh Listing

No discount expected. The vendor is testing the market at their asking price. If the property is fairly priced and desirable, it should attract interest.

4-8 Weeks

Most sales happen within this window. If a property hasn't sold by 6-8 weeks, the vendor might start considering lower offers or price reductions.

8-12 Weeks

Concern territory. Either:

• Priced too high
• Has issues (disclosed or undiscovered)
• Very specific property that suits few buyers
• Poor marketing or unresponsive agent

12+ Weeks

Investigation required. Why hasn't this sold? Possible reasons:

• Significantly overpriced (most common)
• Problematic survey results on previous offers
• Difficult lease terms (leasehold)
• Known issues with the property
• Unrealistic vendor expectations

Extended listing creates opportunity. Vendors become more motivated with time. But understand why it hasn't sold before assuming you've found a bargain.

Price Reduction History

Check whether the price has been reduced. Rightmove and Zoopla show price history for listed properties.

Multiple reductions suggest the vendor is learning what the market will actually pay. The current price might still be too high if it's only come down 5% from an unrealistic starting point.

A single significant reduction (10%+) suggests the vendor has genuinely reassessed. These properties often represent better value than something freshly listed that hasn't been market-tested.

Red Flags in Pricing

Warning signs that a property may be overpriced:

Significantly above comparables - More than 10% above recent sold prices for similar properties, without exceptional features to justify it.

No reductions despite long listing - A property on market for 4+ months at the same price suggests a stubborn vendor. They may be unwilling to negotiate.

Missing square footage - If the listing doesn't include size and the agent is reluctant to provide it, the property may be small for its price point.

Recent purchase at lower price - Check Land Registry for the vendor's purchase price. If they bought two years ago for £280,000 and are now asking £350,000 without major improvements, be sceptical.

Inconsistent agent valuation - If three agents valued at £300-320,000 and this one is listed at £350,000, someone is being optimistic.

Green Flags in Pricing

Indicators of reasonable pricing:

In line with comparables - Asking price matches or sits slightly above recent sales of similar properties.

Good price per square foot - At or below area averages for the property type.

Price to sell signals - Recent reduction, "motivated seller" language, or vendor circumstances (relocation, divorce, estate sale) that prioritise speed over price.

Chain-free seller - Not buying another property, so less likely to demand full asking price to fund their next purchase.

Fresh to market at realistic price - Some agents price realistically from day one rather than starting high. These properties attract early interest and may sell quickly at asking price.

What to Do If Overpriced

Discovering a property you like is overpriced doesn't mean walking away. You have options.

Negotiate

Make an offer reflecting what you believe the property is worth, supported by comparable evidence. A reasonable vendor might accept less than asking rather than wait for a buyer who'll pay full price.

Wait for Reduction

If negotiation fails, you can wait. Properties that don't sell eventually reduce. Set an alert to notify you of price changes.

The risk: someone else might buy it, or the vendor might withdraw it from sale entirely.

Walk Away

Sometimes the best response to an overpriced property is finding a better-priced alternative. If the vendor won't negotiate and the price doesn't reduce, your money might be better spent elsewhere.

The Bottom Line

Property value is subjective, but it's not arbitrary. Comparable sales, price per square foot, and market duration provide objective benchmarks. Use them to assess whether an asking price is realistic.

Don't assume a property is worth its asking price simply because it's listed there. Equally, don't assume a long-listed property is bad. Do the research, understand the market, and make informed decisions about what you're willing to pay. When you're ready to act, understand how much to offer based on your valuation analysis.

The best deals often come from understanding value better than other buyers. Now you have the tools to do exactly that.

Where can I find sold prices for comparable properties?

The Land Registry Price Paid Data is freely available at gov.uk. Enter a postcode to see all recorded sales in that area. Property portals like Rightmove and Zoopla also show sold prices, often with the original listing photos and descriptions.

How accurate is price per square foot as a value measure?

It's useful for rough comparison but has limitations. Premium features (garden, parking, views) add value without adding square footage. Inefficient layouts reduce usable space. Use price per sqft alongside other measures, not as the sole determinant of value.

Should I avoid properties that have been on the market a long time?

Not necessarily. Long-listed properties create negotiation opportunities. But investigate why they haven't sold. Overpricing is the most common reason. If you can establish the property is sound and simply overpriced, a reasonable offer might be accepted by a motivated vendor.

How much below asking price should I offer?

There's no universal answer. In hot markets, asking price or above might be necessary. In normal markets, 3-5% below asking is common. For overpriced or long-listed properties, 10-15% below might be appropriate. Base your offer on comparable evidence, not percentage rules.
