Looking for a found footage film I've seen, probably within the last 10 or 12 years

So this has been driving me nuts!

There is a low budget found footage film that recently popped back into memory but the only problem is, I remember a few bits and peices, nothing more.

So, from what I remember there is a man in a white house that is across the road from a forest, and he is either investigating the death of a family member, or some kind of cult or urban legend.

At some point he meets up with another man and they go into this forest and find a clearing. One night he goes out into that clearing and there is a church or building there.

As far as I remember it ends in the building with him held at gun-point being force onto the floor.

Anyone know which movie this is?! Thanks!
