What market are you located in, OP?
Seems like there has been capitulation in lots of markets, though there are always individual outliers that are not just willing to accept reality and think their home is still worth what someone might have paid at top of bubble in say 2005 or 2006.
Canadians have commented on how expensive their real estate is, but I don't think their market ever popped (their banks were apparently conservative in mortgage lending, requiring the traditional 20% down). Sounds like they may still have a developing bubble, from comments I've seen posted by others.
Regarding property taxes, if your local government has gotten used to all that extra revenue and can't or isn't willing to cut spending, then they will just increase the rate to offset decreased assessments. You can probably just realistically hope that property taxes go up more slowly going forward.
If you are planning on buying with a mortgage, I think there is some sort of rule (forgot specific numbers, but I think it is something like 1% change in mortgage rates is equivalent to 5% effective change in price, when viewed from the point of affordability). Assuming no hyper-inflation down the road, seems like mortgage rates might creep up slowly to more normal 6% range (still low by historical standards), if economy starts to pick up speed in a few years.
