Matt Daimler, a technology wiz with little background in real estate, thinks he can solve some of the most vexing problems in New York City residential sales today.

His new site, Buyfolio.com, which launched Tuesday, allows buyers and brokers to communicate through a single Web page. After seeing listings on sites like Streeteasy.com and the NYTimes.com — or even brokerage sites like Corcoran.com and PrudentialElliman.com — users can save the listing to their personalized Buyfolio.com page and evaluate, compare, and organize them.

Both brokers and clients are welcome to launch pages — for free, for now — and no registration is required. When a listing changes in price or status, or it will be having an open house, the user is notified via e-mail, something Daimler said could eliminate the need to incessantly check listings on their home sites. Also, a broker can use the site to monitor his or her clients. Although the site is exclusively for residential sales in the five boroughs right now, Daimler said he’d be open to other listings, like commercial properties, in the future. [more]
