To be honest with that kind of cash not needing to borrow it would be worth seeing if you could pass selection for the CTC course which gets you placed.
Also with your back ground I suspect that you will have a pretty good chance with the mentored courses with some tax free pay back periods.
You have a fair bit of time so don't commit until the fat bird sings and you have to. Because you have a bit of life experience your way ahead of a lot of the guys of the same age.
