The details of your mortgage may be relevant to the lender evaluating a "repayment holiday" request even if they don't normally facilitate of advertise these. For example what was the original loan amount, how much is outstanding, how long are you into the mortgage term and what is the value of the property? I would imagine that if you have a low LTV and/or are well into the original term and/or have reduced the original capital balance significantly then they might be more inclined to consider this request than if you only recently mortgaged at a high LTV. Maybe ask a good broker for advice?
