For home buyers and sellers, access to timely, detailed information about recently sold properties is critical for making informed decisions. Redfin's significant upgrade now provides near-real-time photos, prices, and details on millions of sold homes, directly empowering consumers. This data is fundamental for conducting a Comparative Market Analysis (CMA), a professional method for determining a property's value, and is enhanced by new features that integrate online property discussions. This article explains how to leverage these tools effectively.
The platform has expanded to include photos and comprehensive details for approximately 1.4 million properties sold within the last two years. This represents a major increase in data depth and freshness. Whereas public records often take weeks or even months to update with only basic facts, this new system aims to display a property's sale photos and details within 15 minutes of the sale being recorded by the agent. This near-real-time access provides a more accurate and immediate view of the market than was previously available to the public. The data is sourced directly from Multiple Listing Services (MLS), which are regional databases used by real estate agents to share property information.
Outside of the Seattle and Washington, D.C. areas, registration is required to view the full details of sold properties. This step, based on our experience assessment, is typically a requirement from the local MLS to ensure data is shared responsibly with serious users. Once registered, you can find this data by visiting the search page and clicking the "More Options" link. Within the expanded search dialog, options for searching past-sales records are located in the bottom left corner. Search results are displayed on a map with light blue icons, and clicking a property reveals extensive details, including original listing information, parcel data, and tax records.
A Comparative Market Analysis (CMA) is a standard method used to estimate a property's value by comparing it to similar homes recently sold in the area. You can perform a basic CMA yourself using the newly available data. Follow these steps:
| Sample CMA for a 2,200 sq ft Home | ||
|---|---|---|
| Comparable Property | Sale Price / Sq Ft | Estimated Value |
| 2,000 sq ft home sold for $800,000 | $400 | $880,000 |
| 2,300 sq ft home sold for $920,000 | $400 | $880,000 |
| 2,100 sq ft home sold for $840,000 | $400 | $880,000 |
This is a simplified example; a full CMA would consider many other factors.
A new feature called blog trackbacks automatically links online commentary back to a property's listing. When a real estate blogger or agent writes about a property and links to its Redfin listing, a reciprocal link is created from the listing page back to the blog post, along with a brief excerpt. This socializes the home buying process by centralizing diverse opinions and can provide valuable insights from local experts. While sellers typically have the option to opt out of this feature, integrating social media can significantly increase a listing's online visibility.
Access to comprehensive, timely sold property data allows consumers to research the market with a level of detail once reserved for real estate agents. By learning to perform a basic CMA, you can establish a realistic price range for a home you wish to buy or sell. This foundational knowledge, combined with insights from blog trackbacks, creates a more transparent and informed real estate experience.
