As to MLS fees, generally, those fees are rolled in with the fees to join NAR, California Association of Realtors, and local real estate association (although some associations offer MLS only subscriptions). 

It’s been a practical way to give my content the initial push it needed.

I watched YouTube videos on this topic where they say not to mention that the LLC is owned by an IRA when you're trying to set the checking account up, or else you'll receive the push back that I received.  

You're the fish.They often use a mix of fear, threat and urgency to push a target to act.It can be as simple as a 24 hours sale from your favorite shop that requires you to log in to your account first or your boss asking you to wire money right now or he/she/they will lose an important contract that will cost millions.So cybersecurity is important because without that, you might have an incident that can cost a lot of money, impact your reputation and might affect your credit score.

I have only been pushed back once or twice on the loan/origination fee, but I get push back on the interest rate every single time.

Newer investors will not understand that if they don't hit a few base hits and get the ball rolling. 

We were interested in rolling money from a sale of a triplex into a larger property.

I’ll push back on this. 

Like the push to get tiny houses accepted and zoning changed,   a "cleanly well run rooming house" business model has yet to get much muninicipal acceptance tracktion.  

They said that per California Revenue and Taxation code, they're asking me to provide them info such as the purchase agreement, rent rolls, etc. to assist them in doing the reappraisal of my property.
