After your PPL, firmly and positivly apply the brakes! Sounds like you have a house and a full time time job. ie your doing well for yourself! Go fishing in the Tearms and Endearment section and Wannabees forum and you see why I have said the above!
Fly for fun or in the Military (if you want a flying career!)
Have a great time on your PPL (Oh and please please please do not deposit that 6k in to some flying schools pocket!)
Pay as you go! I say again
Pay as you go!!
Happy landings
