The average lot size for a single-family home in California is roughly 1/5 acre, so 80 acres would be somewhere around 400 homes. Probably more like 300 after accounting for streets and stuff. Three-story apartment building are around 25 units per acre.

1/10 of an acre is a perfectly good size for a home, especially if you build several stories and a basement.

To say nothing of building 1+5 condos or even more dense highrise stuff.

It will probably end up just being one of the two founding dweebs latest mansion/estate or squatted on for eventual sale.
