Blue Grass Savings Bank v. Community Bank & Trust Company, 941 N.W.2d 20

Blue Grass Savings Bank (Blue Grass) took a mortgage on Stecher Farms in May 2014 containing a statutory § 654.12A notice: “THIS MORTGAGE SECURES CREDIT IN THE AMOUNT OF $148,000.00,” plus a dragnet clause purporting to secure “all present and future debts.”
Blue Grass made multiple loans to Stecher from 2011–2017; by March 2017 Stecher owed Blue Grass about $556,965.32 on various notes (not just the $148,000 purchase-money loan).
On March 18, 2017 Community Bank loaned Stecher ~$589,502 and took a junior mortgage on the same farm; Community Bank reviewed the recorded Blue Grass notice and treated Blue Grass’s priority as capped at $148,000 plus interest.
Blue Grass foreclosed in 2018 claiming first-priority lien for the full indebtedness to it; Community Bank defended, asserting the § 654.12A notice capped Blue Grass’s priority at $148,000.
The district court granted summary judgment to Blue Grass, giving priority to the full debt and allowing an 18% default interest rate; the Iowa Supreme Court reversed, holding priority is capped at $148,000 plus interest and disallowing Blue Grass’s retroactive 18% default interest increase.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the § 654.12A notice caps the first mortgagee’s priority at the stated amount ($148,000) or whether the first mortgagee’s priority extends to all advances made before the junior mortgage was recorded	Blue Grass: the statutory notice only protects advances up to $148,000 made after a junior mortgage is recorded; advances made before the junior mortgage retain common-law priority and are not capped	Community Bank: the statutory notice fixes the maximum priority at $148,000 (plus interest) regardless of when advances were made	Held: The priority is capped at $148,000 plus interest; § 654.12A’s notice establishes the maximum amount senior to subsequently recorded liens, irrespective of timing of advances
Whether Blue Grass may collect an 18% default interest rate retroactively as part of its first-priority claim	Blue Grass: notes permit an increased default rate on default; bank elected to increase rate to 18%	Community Bank: no valid written agreement or continuous charge of 18% prior to summary judgment; retroactive unilateral increase improper	Held: Blue Grass may not collect the retroactive 18% rate; limited to the interest rates it had continuously charged and alleged before the hearing
