Plurchase offers shared real estate search

Sidebar allows users to compare notes

Silicon Valley tech startup Plurchase has launched a collaborative housing search website add-on, the company announced recently.

The Plurchase product is a sidebar that site owners can install to allow their users to shop for homes with whomever they like, whether it be their real estate agent, spouse, or a friend. Users invite friends through Facebook, Twitter, or e-mail from the site. They can then share listings, chat, see what friends are looking at, keep notes, and vote on listings in real time.
