Cost of rewiring 950 sf home

[Alejandro Patino]

Hello, I am currently in the prices of closing on a fixer upper in the St.Louis,MO area.The home is approximately 2 story 950 sf and currently has knob and tube wiring  throughout.I spoke to a electrician who said he would charge me 11k for replacing all the electrical.I’ve never dealt with something like this before, is this a normal cost?.I plan on getting other bids from some more electricians.I’m simple trying to get an idea of what the cost should be.Thanks.
