A spider outside my home builds in the same spot everynight but the web is always fully gone by the morning.

That's fairly common - I suspect that some orb-web spinners do that normally, but for some, at least, the web is left up until it's been so damaged by the things it snares that it has to be replaced. Each web is a huge investment on protein, so the spider will eat and 'reprocess' the web to recover some of the protein it's made of, but that's a fairly big job, so it's pretty common to see the larger webs of older spiders left up even after they're pretty tattered. One possible reason to take the web down at dawn is that it marks the location of the spider for day-hunting predators. I'm not sure how significant a factor this is in the spider's decision, though. Be interesting to explore further (if it hasn't been looked at already).

The average life-span of a spider's web is only a day, so it will be fairly common.
