Partner With Your Own Self-Directed IRA on Real Estate? The 50/50 Rule

“Can I partner with my Roth IRA to invest in a flip or a rental?”

Can you partner with your IRA on a flip or rental? It’s allowed, and it’s also one of the easiest ways to blow up an IRA by accident. In our September live Q&A, guest John Bowens of Equity Trust Company called it “our favorite question,” and his answer was the honest one: it depends.

Quick answer: It depends, and it’s easy to get wrong. You’re a disqualified person to your own IRA, so the deal must be pro rata from day one: if you and your IRA each put in 50%, every profit and expense splits 50/50 for the life of the deal. The test most people miss: you shouldn’t need your IRA to make the deal happen. And on a flip, stick to desk work: hire a general contractor instead of doing the work yourself.

Can you partner with your IRA? Go in 50/50, stay 50/50

When you invest your personal money alongside your IRA, you’re a disqualified person with respect to that IRA, so the transaction has to follow the pro rata (“in proportion to”) rules. Buy a $200,000 property with $100,000 from your IRA and $100,000 of your own, and you’re 50/50, so every profit and every expense must flow 50/50 going forward. And you both have to buy in at the same time: your IRA can’t buy a share of a property you already own. Any disproportionate split creates a prohibited transaction.

The test most people miss: could you have done it without your IRA?

The code also prohibits your IRA from benefiting you personally in the here and now. So you want to be able to show you didn’t rely on your IRA to do the deal. John points to a Department of Labor advisory opinion, 2000-10A, that addresses this: if the only way you could fund your share was by partnering with your IRA, that can be a problem. He hasn’t seen it challenged, but it could be.

Part IRA, part cash: where deals break

Laura’s warning: what people hear is “you can partner,” and they miss the rules. On a flip, the trouble usually comes from services — you, or a company you own 50% or more of, doing work on the property. That’s where deals fall through the cracks. And as John added, if you co-own through an LLC, it’s a partnership for tax purposes, with an annual partnership return.

Desk work vs sweat equity on a flip

There’s no clear definition, so think in examples. Hiring a general contractor (or, on a light rehab, a few separate contractors) can look like desk work. Being at the property every day, cleaning it out and directing 1099 workers looks very different. The conservative approach: hire a general contractor under a written agreement that spells out exactly what they’re doing. If you’re ever audited, you can hand over the agreement, and the contractor can confirm you set foot on the property once, at the end.

A real example: $100K cash + $100K Roth

A listener’s plan: $100,000 of his own money plus $100,000 from his Roth IRA, buying a $150,000 property with a $50,000 rehab done entirely by a general contractor, making it 50/50 on the $200,000 total. John’s answer, with his usual hedge: it should be OK, assuming there are no other prohibited transactions and he didn’t need the IRA’s $100,000 to make the deal happen.
