Teen Haunted Mansion Movie from 80s or 90s

I really hope someone can figure out what the name of this movie is. I don't remember much about the movie except that I was at my aunts house when I was watching it. It was around 1994-1995.

A bunch of twenty-somethings went to this haunted house and there were vampires there and people getting killed, you know, the normal thing that happens in a horror movie. I would say that it is definitely a direct-to-video release and from what I remember and from my knowledge of horror films the movie was made in the late 1980s. I'm pretty sure it had the typical nudity in it as well.

I'm sorry I don't have any more details of the movie but I really hope someone knows this one.

THANKS!
