All well and good taking into account the costs of your training (take heed of the advice offered here on cost overruns - it is bound to happen), but have you accounted for your actual living expenses?
I see figures for accomodation (add extra for any course delays), but nothing for food, bills (gas, electric, water, tv licence, council tax etc), insurance, beer, transport, entertainment (you've still got to wind down and have fun) and so on. Unless you're going to be working part-time during the training (or doing a full-on modular course and continue in your present job) you'll still need money to cover it all. I presume you won't be living at home with the oldies.
It's good to see someone taking advantage of the low cost of borrowing on a mortgage, and rising equity in house values, rather than running off to the robbers at HSBC. Nice one.
