One last hurdle to clear - rehab draw schedule 

Even if he wanted to seller finance the properties to you, he couldn't because the $100k first lien loan is still there and needs to be paid off (unless he is doing a wrap around structure which has its own hurdles).

Again, I think that plays into my theory of getting money is going to be the hurdle in the future, not necessarily the asset class. 

Being an agent comes with its own set of hurdles and if you don't want to be an agent as a career it probably isn't worth the time and cost to get a license. 

I don't have any interest in speaking to these people again as they were rude and unreasonable.

There's a 2.5-3% in commission that they can syphon from traditional brokerage listings until they're all gone and everything is listed through Amazon, fulfilling Bezsos' master plan of selling absolutely everything.This perspective may seem a bit far-fetched, or that it doesn't appreciate the regulatory hurdles, and these are good points.

Would you explain what a stream line refinance is and what hurdles came with the process?

An unreasonably low late fee - let's say $1 - will encourage more people to be on that side of the line, but you could have a late fee of $1000 and you'd still have people paying late (and some that would pay the fee).

Plenty of hurdles to be aware of.

Getting people to 180 their norms and thinking by explaining the benefits is not something they are going to reverse without major mental hurdles to jump .
