I've tried getting in touch with him today but he blocked my phone number (my texts don't deliver and my call goes right to voicemail.

I bought a house last week and am selling a house next week, but I don't know how many doors I have today, unless I effort a count. 

Today it's called Power Flipper 3X.

Next goal is $250k in income through my real estate and stepping away from the day to day management of the properties.

Today is very different as it is all about the management (and not appreciation) compared to past where management could suck but you still had superior apprecation.This will not crash housing of course but all those "creative" deals where people are paying more than market value are going to realize they have no exit. 

Today, that building generates enough passive income to cover his annual retirement contributions.You mentioned taking the 10% penalty, which I’d only recommend as a last resort.

It’s a way to earn solid returns without the day-to-day work.

And probably in ways we can’t fathom today.  

Offset today’s income with depreciation.

I do relatively well in my day job by today's standards but my hourly rate for self managing is closer to that of a surgeon.
