decide when you want to retire
actually it looks as tho you will have to go on to 65.
then get a repayment mortage to end on the year you retire.
I allowed for technnical reasons to allow one mortgage to run into retirement
and something like £400/mo is quite a millstone when you are retired.
Finally - factor in your lump sum when you retire - a sort of useful wind-fall.
Special deals - none you are more likely to drop dead in the four or five years up to sixty so it is unlikely. Do increase life insurance if you can. (term life that is)
