Its a tracker variable 2.4% mortgage of 114000. I know its a great rate but am not keen to invest money.Talked to a BOI guy and he reckoned i should put it in a 4-5 year lump investment he couldnt give exact rate on this all he could say was that the inital investment was garaunteed and things can only improve with equities etc and it would be a good move. Any advice?
