I have inherited a lump sum from my parents who sadly died this summer. Should I pay off (most of) my mortgage, put it in an all-in-one account to offset my mortgage (and keep the capital in case I need it) or just carry on with the mortgage and invest it in savings? I don't know what to do for the best and it's my whole inheritance (I'm only 38 and I won't have anyone to turn to for any money ever again). The pros and cons of each are going round and round in my head but I'm interested in what other people would do in my situation.
