Short leases, flood risk, poor EPC ratings, overpriced comparables, planning issues, stagnant listings. OfferHound surfaces data-visible risk across every key category in 60 seconds.
All derived from Land Registry, Environment Agency, EPC Register, planning portals, and listing metadata — no physical inspection required.
A lease under 85 years costs significantly more to extend and affects mortgage eligibility. Under 70 years, many lenders refuse entirely.
Doubling ground rent clauses — once common in new-builds — can make properties unmortgageable and almost unsaleable. OfferHound flags these from title data.
A restriction on the title register can limit your ability to sell or mortgage the property without third-party consent. Often unnoticed until conveyancing.
When asking price exceeds adjusted comparable evidence by more than 8%, OfferHound flags it. Overpricing often signals an optimistic vendor or a property with hidden issues.
A listing that has sat on Rightmove for 90+ days without price reduction warrants scrutiny. OfferHound surfaces this alongside comparable turnover rates.
Service charges that are disproportionate to the property size or age of building are a leasehold-specific risk flagged in the analysis narrative.
When fewer than three genuine comparables exist in a 12-month window, valuations become unreliable. OfferHound quantifies this uncertainty explicitly.
A property that was reduced, relisted, or previously sold and returned to market may have had a chain collapse or a failed survey — visible in price paid data.
OfferHound checks Environment Agency flood zone data for every property. Zone 2 or 3 designation affects insurance costs, mortgage eligibility, and long-term value — flagged with severity context.
A poor EPC rating (E, F, or G) means high running costs and potential future compliance issues. OfferHound estimates annual energy costs, calculates the retrofit cost to reach Band C, and applies this directly to the valuation.
Refused planning applications, live enforcement notices, or permitted development that was never regularised can affect re-sale and future renovation potential. All visible in local authority planning portal data.
Each analysis card covers one dimension of risk. Hover (or tap on mobile) any card to see a sample output.
Remaining term, extension cost estimate, and mortgage eligibility risk.
Asking price benchmarked against adjusted comparable sold prices.
Known restrictions and encumbrances visible from title data.
Days on market, price history, and comparable absorption rates.
Whether declared charges are proportionate for the property type.
OfferHound categorises risk by severity so you know what to act on and what to monitor.
Lease under 70 years / doubling ground rent. These directly affect mortgageability and resale. In most cases you should walk away, renegotiate heavily, or require the vendor to resolve before exchange.
Overpriced by 10%+ / extended days on market / title restriction. These warrant price negotiation and solicitor scrutiny but don't automatically kill the deal. Use the evidence to negotiate from a documented position.
Thin comparables / 60–85 year lease / slow local market. Worth monitoring and factoring into your offer, but not necessarily a reason to pull out. OfferHound quantifies the uncertainty so you can price it in.
No forms to fill, no waiting for a call-back.
OfferHound pulls the listing details, sold price data from Land Registry, and title information automatically.
Every risk dimension is checked against available data — leasehold, overpricing, flood risk, EPC, planning, and more. Each flag includes a severity rating and plain-English explanation.
Share with your solicitor, mortgage broker, or use as negotiation evidence directly with the agent.
"The lease flag alone was worth ten times the cost. 74 years — we had no idea. The agent hadn't mentioned it. We negotiated £18k off to cover the extension cost."— James R., buying in Manchester
"I'd been looking at this flat for three weeks. OfferHound flagged it as overpriced by 11% and noted 98 days on market. I offered £22,000 below asking and they accepted within a day."— Sophie M., buying in Bristol
