Why would neighbors property taxes be so much lower?

So, in the endless joy of January coming and owing $8200+ in property taxes with homestead, I looked around at the neighbors bills and a substantial portion of them around our neighborhood have significantly, and I mean significantly lower tax bills. They all have the same homestead exemption, some of the homes are worth a little less but in general they are all within $20k to $40k the value of my home yet their bills are half or less. Hell, some of them are sub $3000.

How is that possible? We got one year of "reprieve" last year, yet this year is $1000 more than the year before the property tax help last year so it's a wash.

Thank you
