An action to foreclose a mortgage is governed by a six-year statute of limitations, pursuant to CPLR 213[4]. Even if a mortgage is payable in installments, once a mortgage debt is accelerated, the entire amount is due and the statute of limitations begins to run on the entire debt. Acceleration occurs by the commencement of a foreclosure action wherein the holder of the note elects in the complaint to call due the entire amount secured by the mortgage.
