Key facts: Wisconsin requires a mandatory 30-day waiting period before estate asset distribution under probate rules; estates valued under $50,000 may qualify for simplified probate procedures; inheritors do not assume personal mortgage liability but the debt remains secured against the property; the federal Garn-St. Germain Act protects heirs from due-on-sale clause enforcement upon inheritance; and proper mortgage documentation must be maintained throughout estate administration to ensure tax deductions, insurance coverage, and lender communications remain intact.
