Slipping into the ocean sounds like a landslide, certainly possible but only affecting a small stretch of coast.
The greatest earthquake slip seen is about 40m, usually it is much less. So that is one limit on how much land might submerge.
Further, the big faults along the San Andreas Fault Zone (CA-Mexico border up to Cape Mendocino) are strike slip, moving sideways rather than
vertically, so the coastline would NOT submerge much along that stretch.
Cascadia, the stretch of coast from Cape Mendocino to Vancouver Island, is a subduction, and prone to M9 earthquakes, and might see 20-40m of fault
motion in the worst case. However, most of the motion would consist of the shoreline moving laterally outward, with vertical uplift or down drop of
only a few meters.
So there will not be a big change in the location of the beachfront property.
