Wisconsin home sale before auction

[Nathan Letourneau]

I sent a letter to a western Wisconsin homeowner in foreclosure.  She contacted me tonight less than one week before auction (June 11th).  I am potentially interested and from the initial conversation looks like something I'd like to move forward with.  My question is.....do I have to buy/close on the property before the June 11th auction?  I have access to cash so that is a possibility if the title work can be expedited.  Or will they postpone the sale if there is a purchase agreement in place? I have bought at auction before, but never less than a week before one.  Thanks for any advice.
