I'm trying to use what I recall from database management, to manage my units in Microsoft Access.

If I am going to be dealing with the same agent or many more agents over the course of the year, what would be the best way to organize a database to store this information.

Most of these search companies all pull info from the same 2 or 3 databases. 

@Colleen FerrariMost self directed custodians /administrators do not give any investment, tax, or legal advice.

Is there a database?

You will want to check with your 457 administrator to confirm. 

Proof of Ownership - In CRE, after all the shares of a certain project have been issued, there is a lot of administrative costs around ownership reconciliation.

Does anybody know how to get connected to BP administration?

He will want an administrator/custodian that is 1) Reputable2) Responsive & helpful regarding organizational structure and allowable transactions.3) Reasonable feesI have searched the internet, and it looks like the Gold investment shops have spent more money on SEO than the real estate folks.

The Solo 401k will likely be the better structure for you if you're eligible, which requires self-employment.A few Solo 401k benefits:Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You can take participant loans from the plan.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.
