You can buy a Whole life insurance polity, a big one, pay on it for a period of time. Then you can borrow against half the amount of the life policy, paid back when you die. Find an insurance company that does this, rather than getting a bank loan - which works too.
Anyone that is a single owner (no employees nobody else on payroll) you can invest up to $45k a year (rather than just $15k a year in 401k). Taxes split up a bit different, but you can still get some serious benefits. Like dividend payments, rolling over to IRA for Gold.
I'm for sure no expert, I pay someone for that knowledge.
