I found this in my house today. I thought it was a wolf spider because it was hairy like a wolf spider and sort of the same color, the legs were thick and hairy and had a design on then, but not the normal wolf spider stripes. Overall it just didn't quite seem to have the same markings of the wolf spiders I usually see around here and its abdomen was a little reddish-brown, as you can see in the pic instead of the same color as its body. By its size I'd bet it was an adult, I would guess about quarter sized. It was indoors and was pretty docile, not aggressive or anything.
