If your bank does not allow 1 skipped payment per year, then they may consider a mortgage payment skip as an exception. I don`t think that negative cashflow is typically a good reason for them to allow a skipped payment. They are usually looking for something along the lines of `hardship`.
If you`ve been making biweekly payments, thenyou could ask them to adjust the amortization back for the extra payments. THat could buy you some time.
