are 4-6% property taxes suppose to be normal??

[Jacob Song]

So it says my first home property tax will be 4% and 2nd 3nd or how many properties that I buy in South Carolina will be 6%. Isn't that very high? is this only in south carolina? which charges more property taxes on investment property?

Because my mom, who lives in columbia, SC had a house which was around 130,000 and bought 2nd house which was around 350,000. when she first moved to the 2nd house, the mortgage was only 1700/month. but later the home became 2nd mortgage the monthly payment, because of the taxes monthly escrow became 4000/month. which seemed crazy. is it suppose to be like this?

how about atlanta? florida or big cities are they similar?
