I think the county Register of Deeds (Wisconsin) needs to be notified that the note has been satisfied, so they can remove the mortgage from the property, but what exactly do I need to send them?  

Were you to pay any of the back taxes listed on the sale notice or were those all satisfied by the winning bid price? 

That brings me to another question: Since I plan to have my wife on the LLC but the loan only on my name, do I have to have majority interest and my wife with minority interest in the LLC in order to satisfy that clause my lender mentioned? 

They got their asking price so they are usually satisfied with that.

@Nicholas Weckstein I just got my primary residence mortgage with WF and was incredibly satisfied and happy with them.

She may take the money and still sue you if she isn't satisfied or she may report you to some no-good government agency that will cause you trouble.

Another issue is your lease on residential properties won't really allow you to do repairs, other arrangements need to be made to keep your tenants satisfied and you may not have the authority to comply with ordinances since you aren't the owner.

You are satisfied with their service and recommend them?

People don't make contingencies for the sake of being able to back out,  it allows them to back out if for some reason they cant obtain a mortgage, or if they are not satisfied with the inspection report, or even if they are unable to find an end buyer to assign their rights to a contract.  

I realize that we need to come to a win win where we are both satisfied.
