Anyone know the name of this movie?

I saw this terrible movie a few years ago (less than 5), but I can't think of the name and it's making me crazy. Here's all I remember:

A man and his teen daughter move to a house in a semi-rural area. The daughter is sulky about it, and pissed with her dad. She meets a brooding dark-haired boy (he's got kind of a Nine Inch Nails look) in the new town, but he quickly becomes obsessed with her; at one point he tells her very firmly that she's his boyfriend. She's like, "ok? whatever..." but he gets more and more obsessed, and one night he and 2 friends show up at the house and start menacing her & her dad. The girl calls the sheriff, and when he drives up you think everything will be cool, but as he gets out of his truck, one of the boys just caps him in the head! Somehow they get into the house, and the girl barricades herself into a room. At one point the 3 boys are inside at the top of some stairs. One boy starts to argue with the ringleader– "should we be doing this?" They start to fight, and the ringleader ends up semi-accidentally throwing his friend over the balcony, which kills him. The other boy shuts the hell up. Later he gets killed somehow, too. Later still, the main boy finds the girl locked into a room with an interior window. He writes "BURN" on the glass with his finger, and sets the house on fire. I don't remember how she escapes, but in the end I think she kills him.

What's the name of the movie?

(And no, it's not "Fear" with Mark Wahlberg– it's much more recent.)
