Hi,

Each factor depends on what mortgage company you go through.

Not sure whether there are any mortgages specific to working towards a qualification but if you have graduated through university there are companys who provide graduate mortgages.

Your last 2 questions vary widley fom lender to lender, I'm not sure to max you will be able to borrow will be but i do know some companies will go up to 130% LTV ( i wouldnt advise this as if finances get difficult you dont leave yourself many options).

The best thing you would do would be to talk to an IFA as this is the type of thing specialise in
