For a 250 FT roll of 12-2 copper romex house wiring it costs right now $65.00 at my local hardware store.
The price can change when copper prices go up or down.
You might need 3 or 4 rolls of the 12-2 romex to complete the wiring in the home. So estimate of 4 rolls of romex at $65.00 each is $260.00 for the romex wiring.
Then add in the outlets that you'll need to update and you might be looking at $300.00 for everything.
If you plan to update the service entrance and distribution panel as well then you might be spending $600.00 to complete the rewiring of the house yourself.
It's much cheaper to complete a rewire of a house yourself if you know how as it can cost $3,000.00 or more to have an electrician do the job.
