Second Porch, which lets users find and list available vacation homes via a Facebook app, has raised $1 million in a first round of funding. The company’s pitch: Because all of its vacation home listings are on Facebook, users are able to rent or trade with people they “know and trust” (ie their friends or friends of friends). Basic listings are free, while premium listings cost $99 a year. The biggest competitor in the online vacation home market is HomeAway, which has raised more than $410 million in funding, and has been buying up a string of smaller vacation rental sites.

And, indeed, Second Porch is careful to note in its announcement that it can “compliment” that site “by giving homeowners the controls to integrate their existing calendars and even link back to their listings (there).” The cash is coming from Oregon Angel Fund.
