It's fine to make mistakes on the first one as long as you learn from them and don't make them again. 

That's fine as long as all the payments go directly into your SDIRA. 

Look, I have no idea who Eric is, what type of person he is but I will say after a quick search I saw that he did in fact sell his company for MAJOR $$$ and that he is active in Section 8, no idea if his course is good or garbage but still felt the urge to respond because I am so tired of hearing SCAMMER, find it online to EVERY SINGLE post asking about any course. anyone who actually sells their business and nets 110 mil is NOT going to dive into Section 8 or any real estate for that matter other than fine personal residences etc.. they retire and spend it.. so I dont think so.Plus section 8 is simply not complicated its run by the Sec 8 folks in each city.. nothing magical about that.. its a tough way to go being a section 8 landlord lots of drama.

You feel you have to rebut my comment to bolster/protect your business that’s fine, but I would suggest you steer clear of exposing client financials unless your in the business of fighting legal suites rather than real estate. 

Fine - use what ever suits you.Mortgage acceleration is a choice, not a requirement.

Dollar Tree trash cans are absolutely fine!

I’m still reading the fine print of this bill to see how costs are affected.

One has paused distributions but seems like it'll be fine in the long run.

All the other houses on the street seem to be fine.   

A HELOC on your primary residence can be fine to use, but unlike a loan against an investment property the interest isn't tax deductible.
