It all depends on the what is the shortest path to ground.

Ground is also a relative term for a lightning strike.

When lightning hits the ground, a potential field emanates from that point. The further out the closer to 0V the potential difference is.

As such it depends on where the strike is in comparison to the house, your wiring, where your house is grounded etc.

For example, if the grounding point on your house is very close to the strike, your house ground will be raised to the voltage of that point away from the stike.

The path to 0V may be through your active wiring, your powesupply, the house frame or the water pipes.

So yeah, hope that helps
