interestingly - just called bank they said no way would they give a payment break unless payment of same was a problem. i explained that not a problem, but that i may require back surgery later in year and examining possibility of pmt break for few months... he said, no. but there was a tiny chance that original mortgage offer mite have a clause in it, would i look it up and send a copy of it to them.
so...... in reality its easier get off paying it if i said i was in difficulty rather than a genuine reason. i did say would be back to paying full thing immediately after the break........
