Chuck, Generally in Ventura County taxes are based an average of .0125% of the roll value, some areas are much higher and some are lower. Each area is slightly different and there is no accurate figure to give but this average is what is quoted by the Assessor's office. Currently homes on Lehigh and Brookshire Sts are assessed an annual property tax based on approximately .10057% of the assessed value. This factor of .10057% is subject to change. In addition to your annual taxes, if you purchase a home, will be subject to a one time supplemental tax as well. This is based on the difference of the price paid (or market value) and the current assessment. The supplemental taxes are then allocated by the number of days you owned it in the fiscal year. This is a confusing calculation for most people. But remember, the supplemental tax is a one time tax for purchases (and assessable new construction). Under Proposition 13 the value of your home will be automatically increased for property taxes by no more than 2% per year. This increase is based on the Consumer Price Index. If the CPI does not go up 2% then the increase is less. For instance the 2010 value is basically going to stay the same or slightly less. Check the Assessor's website for more information.
