I started out the route of aviation degree with ratings and big loans. Even with scholarships, I amassed $60k plus In students loans and was about 2/3 the way to commercial after two years. I was working 2 or 3 part-time jobs so that cut into my time to fly. I left the program in 2006 and transferred to mechanical engineering thinking that after a few years of an engineering career and hopefully a recovery in the airline industry that I would go back. Here I am, 13 years later still paying the loans. My brother in law just finished an accelerated program, ATP, and amassed about $70k in loans for aviation and another $20k in loans to finish his bachelor degree. It paid off in that he now has a job with a regional. It will be a grind paying back those loans AND starting a family, wedding, house, etc. (Ask me how I know) I stopped flying for about 12 years and picked it back up recently to get back on course for the dream, this time paying for it cash from a second job.
I bought a share of a plane to time build and build proficiency back up. You can look into that. Less upfront overhead than buying a plane outright. Usually clubs have a member or two that give free or discounted instruction.
The allure of a one stop shop is really strong and has worked for a lot of people. No matter how you slice it, it will be a grind.
