Sometimes, working in real estate can be all about crunching numbers and analyzing data. But there’s an emotional and creative side, too, and Redfin’s new photo-sharing service hopes to tap into that.

It’s called Collections, a new social feature that allows users to create and share sets of listing photos. People can create Collections on any topic, such as “City Views,” or “Great Escapes,” and share them through social media or email.

The service is integrated with Redfin’s business. Each photo of a home in a Collection links to the home’s listing details page on Redfin, including the price of the home and the location on Google Maps.

“After years of building the nerdiest real estate site on the web, Redfin got all gushy about pretty houses,” Glenn Kelman, Redfin CEO, said in a press release. “Along the way, we discovered how much fun it is to compare pictures of oceanic pools, bizarre bathrooms, palatial tree-houses and overstuffed libraries. As website creators and as real estate agents, the conversations we want with our customers aren’t just about the price-per-square-foot but also about the lusted-after and the wacky, the homes like this but not like that, and the design ideas we want to steal.”

Seattle-based Redfin couldn’t simply use another photo-sharing site for something like this because, as a broker, the company must give attribution to the listing agent and respect the seller’s wishes around whether the property can be discussed.

Users can “follow” individual Collections, and be notified by email whenever a new photo of a gorgeous kitchen or a cute kids’ room is added.

This is similar to a new real estate photo-sharing service that we just wrote about called Abodograph. The main difference is that Abodograph is for realtors to share their own photos, while Collections was built for consumers from the ground up.

Redfin is celebrating its 10th anniversary this year. The company announced last month that it has saved customers more than $100 million in real estate fees since it was founded (and topped $8 billion in home sales). Interestingly, more than $25 million of the real estate savings have come this year.

The company also is growing at its Seattle headquarters and is prepping to double its office space. Redfin now boasts more than 500 agents in 19 markets.
