Your IRA is allowed to own real estate, private mortgage notes, and private loans. Stocks, bonds, and funds are not the whole list. The IRS never said the account had to hold a fund menu, your brokerage decided that. The account itself is a tax wrapper, and the same traditional or Roth IRA can point at real income-producing assets the moment it sits with the right type of custodian. That's what self directed IRA real estate actually means, and after 59½, when you can move that money penalty-free, is when it starts to matter.
What the account is allowed to hold
A self-directed IRA can hold real estate: residential, commercial, raw land, even a piece of property overseas. It can hold private mortgage notes, where your account becomes the lender and someone pays it back with interest. It can make private loans, buy tax liens, and hold physical gold and silver.
There's a short list of things it can't hold. Life insurance is out. Collectibles are out, so no art, antiques, rare coins, or fine wine. You also can't hold stock in an S corporation. Outside of those, the doors are wide open.
Self-directed sounds exotic, and it isn't. It's the same traditional or Roth IRA you already know, with the same contribution limits and the same withdrawal rules you already follow. The only thing that changes is what you're allowed to put inside it. Same wrapper, different menu.
How the money gets there, and why 59½ matters
You move the account to what's called a self-directed custodian. A few of the big names are Equity Trust, Directed IRA, and IRA Financial. Every IRA has a custodian by law, and your brokerage is one too. It just limits what it sells, which is stocks, bonds, and funds. A self-directed custodian is approved to hold the other stuff.
Understand the catch going in. These custodians are passive. They don't vet your deals and they don't give investment advice. They hold title for your IRA, move money when you tell them to, and file the paperwork. The decisions are all yours. The account owns the assets, not you personally, so the title literally reads "the custodian for the benefit of your IRA." That detail is where a lot of the rules come from.
Getting the money over is simpler than it sounds. The cleanest way is a direct transfer, custodian to custodian. The money moves from your current account straight into the new one and you never touch it. No taxable event, no withholding, no penalty, and no limit on how often you can do it. An old 401(k) sitting at a former employer rolls over the same way, straight from the plan to the new custodian. One warning: if the check gets made out to you instead of the custodian, the plan has to hold back 20% for taxes and you're on a 60-day clock to put it all back.
The age matters for one reason. A lot of 401(k) plans won't let you move money out while you're still working there, and once you hit 59½, many of them will. At that age you can reposition retirement money without a penalty even if you haven't retired yet. If your money is already in an IRA or in an account from a former employer, you can do this at any age.
The fee only looks expensive next to free
Self-directed custodians charge somewhere around $200 to $2,000 per year, and you pay it directly. Your gut says no thanks, my regular IRA is free. Your regular IRA is not free. It isn't even close. You just don't see what you're paying.
Say you have $500,000 in a managed account and you're paying a 1% advisory fee. That's about $5,000 a year. You never write a check for it. It comes out of your returns before you ever see a statement, so it doesn't feel like a fee, and it is one, every single year. The self-directed custodian flips that around. You pay a flat fee directly and you keep every dollar your investments earn. Compare the $2,000 to the right number.
If you run your own money in a couple of low-cost index funds, you're already paying close to nothing, and that's fine. This comparison is for money sitting in managed accounts or pricier funds.
The rules that decide whether this works
The rules are strict and they aren't a trap. They exist to stop you from using the account to benefit yourself today instead of in retirement. The IRS calls a certain group disqualified persons, and your IRA can't do business with any of them. That group includes you, your spouse, your parents, your grandparents, your kids and grandkids, and their spouses. Your IRA can't buy from them, sell to them, or lend to them.
If your IRA owns real estate, it gets specific. Every expense gets paid by the IRA and every dollar of income goes back into the IRA. You can't live in the property or stay there for a night, your family can't use it, and you can't do the work yourself. If the sink breaks, you can't go fix it, even if you're a plumber. Your own labor counts as putting value into the account in a way the rules don't allow, so you hire it out. You own the place and you keep your hands off it. That's the trade for the tax shelter.
One more rule matters. If you borrow money to buy property inside your IRA, the part you bought with the loan still gets taxed, right inside the account that's supposed to be tax-free. Leverage, the thing that makes real estate work outside a tax shelter, works against you here.
Breaking a rule is serious. Genuine self-dealing can cost the account its tax shelter, and that's a tax bill you don't want. It isn't a hair trigger that punishes honest mistakes, and administrative errors caught fast sometimes have a short window to unwind. Know the rules, and hire a custodian and a good CPA who know them too. This is not the place to wing it.
Why a rental usually belongs outside the account
The obvious move is to buy a rental property inside the IRA, and for most people that's the wrong asset to put in there. The rules fight a hands-on landlord at every turn. You can't manage it, you can't fix it, you can't pay for anything out of your own pocket. I own a couple dozen rentals personally and run them all myself, so a place I'm not even allowed to fix would drive me crazy. You also need cash sitting idle in the IRA for vacancies and repairs, and if you financed it, you're paying that tax.
The bigger reason is tax. A rental is already one of the most tax-advantaged things you can own when you hold it outside a retirement account. Depreciation shelters the income. A 1031 exchange lets you roll gains into the next property and put off the tax. You get the mortgage interest write-off, long-term capital gain rates when you sell, and a stepped-up basis that can wipe out the gain entirely if you leave it to your kids.
Put that same rental inside a traditional IRA and you lose every one of those. The IRA doesn't file a tax return, so there's nothing to depreciate against. Money that would have been taxed at a low capital gains rate on the outside comes out of a traditional IRA as ordinary income. You take one of the best tax breaks in the whole code and turn it into a tax hike. It's a bad trade.
Lending on the building instead of owning it
Real estate isn't off the table inside your IRA. You just don't want to own and operate the building. The move that works in these accounts is loaning on the building. Your IRA acts as the lender and puts up the money, a borrower buys the property with that cash, and they pay the IRA back over time with interest. This is a secured mortgage note, also called private lending. You stop being the landlord and start being the bank. I've lent on mortgage notes myself for years.
Look at how cleanly it fits the rules. The income is interest, so the leverage tax problem doesn't apply, because your IRA is the lender rather than the borrower. There's nothing for you to repair, so the sweat equity rule never comes up. There's no property for you or your family to accidentally use. The only things moving are money going out and payments coming back in, which means fewer transactions and lower custodian fees.
It's also secured. A first position lien on real property sits behind the loan, so if the borrower stops paying, the property stands behind the money. That's why, when someone asks me how to do real estate inside a retirement account, I point them at being the bank.
