Negotiating purchase before owner had to foreclose!

[Philip Murphy]

I have a question about a property that is possibly soon to be foreclosed. The owner has a mortgage on it still and is behind on property taxes. My assumption is that when negotiating the purchase of the property I would have to pay off the mortgage, or would I be able to Pay off the taxes and maybe provide the current owner with some cash and then work with the bank on the mortgage?

How does that process work?
