Where can I find a Mortgage calculator that will also estimate property tax?
You can’t, because property tax varies widely on similarly priced houses depending on many factors, mainly where the house is.
Many counties have their assessments online, so you might be able to find out what taxes are on similar houses in the area where you are looking.
