My latest opinion is nope not worth it. Find an FBO with good planes/CFIs and a Twin.. Knock out your time build hours with a safety pilot splitting the cost.. Joining a flying club is a great option too and you can make the rental worth it (keep the plane for a weekend getaway etc. They are more flexible than schools). Get the Jepp books and study on your down time.. No need to make this more expensive than it already is. Also fly at night and make every flight a Cross Country.. Then you can have most of the ATP R requirements met before you even start working as a CFI (then you can fly for the needs of your students and not yourself). Practice stalls all the way to an airport 50 NM away, land there, then fly back.. Do a few steep turns etc on the way (avoid doing this near VORs etc.) Log the XC time. (Do this stuff during the day of course but straight and level on the nights)

You can probably nail this for under 35 grand.
Work a day job and ENJOY your training.. Don't make it stressful.. Come out debt free and only accept flying jobs that pay at least an OK amount.

Now you also have the benefit of a backup career..
