Seller costs for LA county

[Susan Rauch]

We are currently in escrow on the sale of our home located in the unincorporated area of LA county. On the grant deed a “City Tax” of $6975 is indicated, then the line indicated “unincorporated area” is checked. Is this correct? Sale price of home is between 1.5 & 1.6 mil. I’ve tried to research how this “city tax” fee is calculated for LA county with no luck, and why do they charge a “city tax” when I don’t live in a city? Thanks for looking!
