18M Starting Tech Apprenticeship - Advice for FIRE Journey?

I'm 18M, about to start a degree apprenticeship in tech with a salary for the first time.

My costs are quite low (living at home etc) so I can put away about half my salary for saving/investment.

Current Plan:

• Save up during my apprenticeship for a house deposit in a low COL area
• Use rental income to cover the mortgage (10 year)
• Eventually have that property generate passive income

Is anyone willing to share some advice on how I can best use these savings/investments to help me reach FIRE?

Any other suggestions or critiques of my current plan would be much appreciated!

Thanks!
