No. 2 bank overcharged troops on mortgages - Business - Real estate - Mortgage Mess - msnbc.com One of the nation's biggest banks — JP Morgan Chase — admits it has overcharged several thousand military families for their mortgages, including families of troops fighting in Afghanistan. The bank also tells NBC News that it improperly foreclosed on more than a dozen military families. The admissions are an outgrowth of a lawsuit filed by Marine Capt. Jonathan Rowles. Rowles is the backseat pilot of an F/A 18 Delta fighter jet and has served the nation as a Marine for five years. He and his wife, Julia, say they’ve been battling Chase almost that long.
