I am curious to know if any experienced investors or contractors could give me a ballpark number on how much it would cost me to build a 500sqft guest house in my back yard in San Jose. Basically a small studio with a small bathroom.

Ballpark estimate is $170 per sf, but it varies a lot. It can be much cheaper if you find the right contractor. I have a friend who built one for $20K, around 600 sf, no permit.
