Have I achieved the ultimate SDIRA structure for myself? Critiques?

[Tom Russell]

First I set up a passive SDIRA (recommendations?)

Then I fund the SDIRA by transfering money from my existing IRA

Then I set up an S Corp (Object of S Corp is to flip houses and occasional buy and hold, I will be taking a reasonable salary and the flow through goes to dividends thereby reducing some of the taxes vs an LLC.)

The SDIRA will purchase the majority of shares of the SCorp thereby funding it's operations.

Aside from being careful of the Corporate requirements (register dba name, holding shareholder meetings, annual reports, filings ect.)  Is there any thing wrong with this structure or something that I have missed?
