I'll be closing a $345k 12 unit tomorrow and that will put me at just under $10k a month in total principal and interest payments on my 42 units.

I'll continue to build my portfolio, but that's a decent number to think about as far as a monthly income when they're all paid off in 20-25 years. I'm 37 and can definitely see myself having a $250k a year "draw" from my business in my late 50's if not sooner!
