Want to know what your home is worth? The most reliable starting point is what similar properties have actually sold for nearby — real prices straight from HM Land Registry, not estimates.
Search any street, town or postcode to see exactly what homes have sold for. Comparing recent sales of similar properties on your street — same type, same size, same area — is the best free guide there is to your own home's value, and it's the same evidence estate agents and surveyors use.
What about instant online valuation tools?
The free "instant valuation" tools offered by the major property portals estimate a figure using Land Registry data and market trends. They're handy for a quick ballpark, but they can't see inside your home — so they won't reflect its condition, an extension, a new kitchen, or anything that makes your property different from its neighbours.
For an accurate figure, combine the sold-price evidence above with a free valuation from a local estate agent, who can take your property's specific features into account.
