Do I have the math right here? $600 million divided by 100,000 homeowners is $6,000 each on average, over 6 years' time is $1,000 per year overcharge on property taxes. I'm wondering specifically about the foreclosure rate. Were the foreclosures strictly due to not paying the extra $1K per year? Or were they due to not paying any amount of tax due (including the bulk of it which was not an overcharge). The article doesn't say. [edit]: now I re-read a bit, the article actually does not state how many total taxpayers were affected, only those that were foreclosed on. There is also one anecdote at the end about how one person was over-taxed $4,000.
