But, if you know the homeowner's name or the legal description, you might be able to google it because some of the local newspapers put their public notices online. The address will NOT be in the public announcement of the foreclosure. So here is what you can try...
1) Counties in Minnesota follow the same basic format for their website URLs: http://www.co._____.mn.us
where the _____ is the name of the county. For example, Anoka County's website is: http://www.co.anoka.mn.us. Go to the county website where the property is located and they will have a property information or property tax link somewhere. All counties are different so you may have to look around a little bit, but you should be able to find a place where you can put in an address and get the basic information on the property.
2) Use the information from the county website and find the legal description - write it down. Most homes in developed neighborhoods are going to be something like: "Lot 7, Block 3, Happy Acres Estates" or something along those lines (Happy Acres Estates is just something I made up for this example).
3) The owners name will also be in the basic information on the county website. Write that down, unless it is a bank. If it is a bank, then just use the legal description.
Google the legal description and homeowners last name. You might also have to add the words "sheriff" or "mortgage" or "foreclosure", but in many cases, the public announcement will pop right up. That will tell you when the Sheriff's Sale is going to be.
I hope that helps!
