Find someone with an IRA that would like a nice return.

In this case you'd work with someone who has available capital that is perhaps sitting in a bank account, CD, IRA or 401K and who wants to earn a higher rate of return on their money.

use a bank statement, IRA or brokerage statement if you can, you are not showing where the $$ is coming from, just showing you can close.

I herd a little some thing about taking and putting it in to an IRA account.

Hi, if you have a solid deal, try PENSCO TRUST, they make loans from self directed IRAs, not an endorsement, just a suggestion.

My business model and history don't coincide with wholesaling, but I'm thinking of doing some wholesale deals with my self directed IRA.

I’m not an expert on markets, trends, etc. and my investments are pretty basic (rentals, ira’s at Vanguard).

Are the proceeds sitting in a bank ready to deploy OR is this part of a 1031 or IRA money etc.??

Whether that looks like a self-directed IRA, 401K loan, straight up cashing out retirement funds and paying taxes & penalties, or any other way to use retirement funds. 

The funds I have to invest in RE are "post tax", but I suppose I could allocate differently and use IRA funds, but I would be more limited how much I could invested vs post tax $,
