The listing says "Reduced on 3 September". The agent says the sellers are "keen to move". Both are true and neither is an explanation. A price cut is an event with a cause, and the cause decides whether the new price is a bargain, a fair correction, or the first step in a long slide. You cannot always find out. You can nearly always narrow it down.
What does the listing's own history tell you?
Start with the dates. Portals show when a listing was added and when the price last changed, and free tracking tools keep the versions between. A house listed in March at £425,000, cut in June to £399,950 and again in August to £385,000 has been through two rounds of "no one is offering at this", which is different from a house cut once, sharply, a fortnight after a sale was agreed.
Watch for the resets. "Back on the market" after weeks under offer usually means a sale fell through. A listing that vanishes and reappears with a different agent, new photos and "new to market" at the top has not become a new house; it has been relisted, and the added date has gone back to zero. Comparing the photos with the old listing (same sofa, different lens) is enough to catch it [check: house-history].
How does the price trail map to events?
Timing is the tell. A reduction two to six weeks after "sold subject to contract" appeared, with the house then back on the market, points to something the buyer found: a survey, a search result, a lender valuation that came in low. A reduction straight after a planning application went in next door is worth a look at the council's planning register. A steady drip of small cuts with no under offer period points to a price set by hope rather than the street's sold prices.
Then check the record. Land Registry price paid data shows what this house and its neighbours actually sold for and when, which is the number the lender's valuer works from. The EPC register shows when the last assessment was done, and a fresh EPC on a house "in the family for 40 years" tells you when the sellers started preparing. A house bought two years ago and back on at a higher price with no visible work is a question, not an accusation.
What should I ask the agent at each change?
Agents have to tell you material information they know about, including why a previous sale fell through [VERIFY current guidance]. So ask, plainly and in writing: "The listing shows a reduction on 3 September. What prompted it?" "The house was under offer in June. What happened to that sale?" "Was there a survey, and can I see it?" "Has the seller had any offers at the new price?" "Why did the seller change agents?" Vagueness is an answer of a kind. A survey the previous buyer paid for is sometimes available for the asking, the best £0 you will spend.
How do I negotiate with information rather than instinct?
An offer that says "I feel it is worth £370,000" goes nowhere. An offer that says "three sales in this road in the last year averaged £362,000, the house has been listed for 26 weeks, one sale has already fallen through, and the EPC is an F, so I am offering £372,000" is a different conversation, because the agent has to take it to the seller with the numbers attached. You are not pointing at flaws, you are pointing at the record. If the seller says no, you have learned where their floor is.
How Eavesdrop checks this
Eavesdrop's On the record tell reads Land Registry price paid data for the house and the street, the EPC register for assessment dates and ratings, Historic England's list for listed status, and the listing's own price and date changes, and lays them out in order with every fact cited [check: epc]. Before you offer. Before you sign. Eavesdrop.
Quick answers
Why do houses get reduced on Rightmove? Most often because the first price found no buyer, a sale fell through after a survey or search, or the seller's circumstances changed. The timing of the cut usually points to which.
How can I tell how long a house has been on the market? Check the listing's added date, but also look for earlier versions under other agents, since relisting resets the date. Free listing history tools and Land Registry data fill the gaps.
Does an estate agent have to tell me why a sale fell through? Agents must disclose material information they know that would affect a buyer's decision, so ask directly and in writing [VERIFY current guidance].
