WELLFLEET, Mass. — A Cape Cod homeowner is taking JP Morgan Chase to court, arguing the bank should have known better than to finance a $5.5 million mortgage on a mansion teetering on the edge of an eroding bluff. John Bonomi Jr., who purchased the 5,817-square-foot estate in 2021, now says he was in the throes of a manic episode when he signed the loan papers, and the bank is partly to blame for his financial predicament.
The property, located just 12 to 14 feet from the edge of a rapidly receding escarpment overlooking Cape Cod Bay, was flagged by local conservationists years before the purchase. They warned that the shoreline was eroding at a rate of six feet per year, a pace accelerated by rising sea levels. Despite those warnings, the mortgage was approved, and Bonomi closed on the deal.
Fast forward to today, and the situation has only worsened. The relentless pounding of ocean waves has further undermined the foundation, and the mansion's long-term viability is in serious doubt. Bonomi's lawsuit, filed in a Massachusetts court, seeks to recoup his losses, arguing that Chase should have recognized the property's perilous condition and the buyer's impaired judgment.
According to the Boston Globe, Bonomi's legal strategy centers on his mental health. The lawsuit states that he was “acting under an uncontrollable manic psychosis at the time” he agreed to the mortgage terms. Bonomi has a documented diagnosis of bipolar disorder, a condition that the suit says is characterized by “irrational risk-taking and impulsive behavior, including reckless spending.”
“No rational person… would have considered purchasing the Property, and certainly not at the full asking price,” the complaint reads. The argument raises a pointed question: why would a major financial institution green-light a loan on a property that experts had publicly warned was at risk of falling into the ocean?
Chase, for its part, initially sought to have the case dismissed. In May, the bank filed a response denying the allegations, stating that “to the extent a response is required, Chase denies the allegations contained therein and leaves Plaintiff to his proofs.” The bank has not commented further on the specifics of the case.
Legal experts following the case note that lawsuits challenging mortgage approvals on the basis of mental incapacity are rare and face a high bar. Courts typically require substantial evidence that the borrower was unable to understand the transaction at the time it was made, and that the lender was aware of or should have been aware of the borrower's condition.
For Bonomi, the stakes are high. If the court rules in his favor, he could be relieved of the mortgage obligation, but he would still face the loss of the property. If the court sides with Chase, he remains on the hook for a loan on a home that may soon be uninhabitable.
The case also highlights a broader issue along the Massachusetts coast, where erosion and sea-level rise are forcing homeowners and lenders to confront the long-term viability of coastal properties. While this lawsuit is unusual in its focus on the borrower's mental state, it underscores the growing tension between real estate development and environmental reality.
As the legal battle unfolds, the mansion itself remains perched on the bluff, a stark reminder of the forces that are reshaping the Cape Cod shoreline. For now, the courts will decide who bears the financial burden of a decision that many saw as doomed from the start.
