Hey Chris,
I would say you are definately not too young to start property investing!I started at age 21 and have just kept going with my goals slowly but surely.I am now 30 and have semi retired because of property.It all happens one step at a time.
I would suggest to just be wise with where you spend your money without being a mega-tighty(remember life is for living but just keep your goals in view).In saying this be a commited worker with honesty and integrity( no matter where you work to earn your deposit ).You will find yourself getting promoted or realise the faith to get a better job.
I really encourage you to go for it Chris!
