then u must have an established relationship with them bc most would just cut you out.  

Most likely you will establish a Solo 401(k), due to the additional benefits, some of which were already mentioned.

As a property manager, creating a standard that establishes the trifecta of benefits and tension is good. 

But will just depend on what you are trying to establish.

Of course establishing what the assessed value was 20 years ago is less obvious.

The majority of my properties are in a very established neighborhood/area that would wage an all out war for a developer looking to build property that would compete with me.  

I am hoping to find an opportunity to help an established Investor with any administrative tasks, social media, or marketing in exchange for a chance to learn.

I teach how to establish credibility through my concept, The 3 Pillars of Conversion, which I’ve developed to help clients succeed regardless of location or age—as long as they target the right audience.Lastly: You’ve accused me of “selling SEO.”

Establishing a great relationship with a mentor or group that is actively doing this would be great!

Furthermore unless you have a Roth IRA (can't move into Solo 401k) there really isn't a good reason to establish an SDIRA and a Solo 401k since you can do everything in the Solo 401k.
