I think you're chances are good - it seems from reading your post that you want to borrow €225k on a salary of almost €80k. You have good savings and an extra in your favour is the fact that one of you has a govt. position. Therefore, you are going into this with a strong hand.
Just make sure to keep your savings up between now and the time you apply and also make sure that you keep your credit history clear as Liam says don't exceed your overdraft or miss a loan payment, direct debit etc.
Also keep your paperwork in order eg copies of bank statements, your P60 etc. You will be asked for loads of this during the application process.
Try to relax, you are in a very strong position, your chances are better than most. You have covered everything that's in your control, you can't see the future or know how your application is going to be viewed, so don't worry about it.
