@Maria Jeanette Using a self-directed IRA (SDIRA) for real estate investment offers control over asset selection and tax advantages, such as tax-deferred growth (Traditional IRA) or tax-free growth (Roth IRA).

So it is really looking more at bank deposits, but most mom and pop owners won't share bank statements.  

So any asset that can be attached by a U.S. court; bank accounts (even most foreign bank accounts), stocks, bonds, real estate can be taken once the trust is declared as a sham or the transfer of assets to the trust is found to be fraudulent.Further, once this has occurred the defendant will be required to testify under oath about the assets in the trust.  

As of my last update in April 2023, the definition of an accredited investor includes, but is not limited to, the following:Income: Individuals who have had an income of more than $200,000 (or $300,000 together with a spouse) for the past two years and expect the same for the current year.Net Worth: Individuals with a net worth exceeding $1 million, either alone or together with a spouse, excluding the value of the person's primary residence.Insiders: Directors, executive officers, and general partners of the company selling the securities.Professional Experience: Certain professional certifications, designations, or credentials or other credentials issued by an accredited educational institution may allow an individual to be considered accredited.Knowledgeable Employees: In the case of private funds, "knowledgeable employees" of the fund are also considered accredited investors.Institutions: Banks, partnerships, corporations, nonprofits, and trusts with assets exceeding $5 million.By imposing these criteria, Regulation D is meant to ensure that all participants in such an offering are capable of fending for themselves or sustaining the risk of loss, thus requiring less regulatory protection.Under Rule 506(c), it is not enough for an investor to simply claim accredited status.

The best HELOC usually comes from the bank where you have the most money or the one you have the best relationship with.
