Sold a condo in south Denver and used those proceeds along with $2,000 borrowed from my Roth IRA account.

I can't directly contribute to a ROTH IRA, I didn't get any stimulus checks, my income phases me out for many losses (they have to be passed forward or simply forgone), the list goes on.

I have seen options where you can invest as little as $500 and target an 8% return which for those with low dollar IRA's or money sitting on the sidelines is another way to put it to work. 

We took a risk given the potential reward of the business and have been living off of our savings and IRA.

House, 401k, IRA etc.

C) Have a Roth IRA with $80k D) Have a 401k with $200k in it.

Get your systems in place and learn MORE ways to purchase deals like sub to, seller financing, getting owner to take back a 2nd and using friends and family's self directed IRA. 

These are my top 7 reasons for investing in notes:• Generate interest income• Purchase at a discount for increased yield• Backed by real estate as security• Less hands-on than owning property• Licensed third party servicers can manage payments and collections • Ability to re-work the note, take a deed in lieu, or take the property back through foreclosure in the event of non-payment• Profits are tax-deferred (or even tax-free with a Roth IRA).

Investor and my IRA(or SDIRA/LLC)  would be on the deed, and only make interest on the money loaned. 

If you have funds in SD IRA - you have to invest inside of a tax-deferred vehicle, and that really has nothing to do with using a HELOC.
