Buyer guide

Rightmove offer calculator

The short answer: the fastest way to know what to offer on a home you've found on Rightmove is to check the listing against what comparable properties have actually sold for — not against its asking price. Paste the link, and HouseOffer turns the listing into an independent view of value and a recommended opening offer.

From a listing you like to an offer you can defend

You've found the one. The asking price is right there, and it's already shaping what you think is reasonable. Before it does, it's worth seeing the home through the data instead of the agent's number: what similar properties nearby have sold for, how the market has moved since, and how long this one has been listed.

What the data adds to the listing

A Rightmove listing tells you the asking price, the photos, and — if you dig — the price history. What it can't tell you is what the home is worth. That comes from completed sales: the prices similar homes actually changed hands for, held by HM Land Registry, adjusted to today's value. Set the asking price against that, and you can see immediately whether it's ahead of the market, in line with it, or a genuine opportunity to move on quickly.

How it works

Paste the property link. HouseOffer pulls the comparable sold data, adjusts it for time using the House Price Index, factors in days on the market, and returns an independent view of value with a recommended opening offer — free to start. It's not affiliated with Rightmove; it's the buyer-side read the portals don't give you.
