Property Proof vs HouseSigma: Records vs Sold Data

HouseSigma is one of the most popular tools for Canadian buyers researching MLS sold prices and market trends. Property Proof answers a different question: not "what did it sell for?" but "what does the official record say about this property?" The two are complementary. HouseSigma helps you decide what to offer; Property Proof helps you decide whether to offer at all, and what conditions to attach.

Why Sold Prices Aren't in a Property History Report

In most Canadian provinces, historical residential sale prices are not fully public record, because access to MLS sold data is restricted to licensed real estate professionals and platforms with board agreements. Property Proof only reports publicly accessible records, so sale prices are out of scope by design.

What Sold Data Can't Tell You

A property can have a clean price history and still carry an open building permit from an uninspected renovation, sit inside a mapped flood hazard area, or have zoning that rules out the suite you're planning. Those findings live in municipal and provincial records, not in MLS data. Property Proof compiles a permit timeline with status classification, zoning with plain-language explanation, official flood mapping checks, infrastructure context, and a parcel-confirmed title summary for Alberta addresses, for residential properties in 14 Canadian markets, delivered in under a minute for $49 CAD.
