They suggested a 60-day notice, but I don't think that is enforceable. 

The thing is, WI law says a landlord must provide 60 days notice if a 12 month is going to be renewed or not - the lease says nothing about this either way.

I agreed and she has been on a M2M lease for the past 13 months.I continue to notice very similar SFRs in my community pop up on Zillow for rent well above $2,300.

It should not take a month and a half to get into the unit. all that is required is 24/48 hour notice. tenant permission is not.

I called a friend who is a private lender and he said he can try to salvage the deal so we tried to move this deal over to his bank before The Bank’s underwriting could officially decline it.Thankfully everything went well and the deal was officially transferred over to the private lender without an official decline notice from The Bank.

Have you noticed flood insurance is this expensive?

I believe you have missed a crucial step here that possibly puts you in a bad position where it might not be possible to deny the wife accessDid either party give the 30 days notice required to terminate the existing lease?

If you notice any new capital, make sure you request the Seller to transfer the warranties at closing. 

What I've noticed helps prevent them are 1.

You would just need to ask them to not renew the lease or give notice to a month to month lease.
