Remember there's a big difference between Clark County and the other sixteen counties in the state.
Clark County (Las Vegas, Henderson, Mesquite, Laughlin -- and some bleedover into Pahrump, which is actually in Nye County) has seen the prices and such skyrocket. The rest of the state, not so much.
The actual property tax increases for the 2007-2008 tax year are capped at 3% or 8% or twice the CPI (whichever is greater) of the prior year's tax bill for most properties.
The assessed value of my home went up 10% -- but there's the cap on the taxes themselves, not the assessed values.
Of course, we're hitting our Tax Freedom Day something like fifth or sixth from last this year, so that's not exactly a ringing endorsement.
