214k in a Roth SDIRA and the UBIT drag won't pencil

The number you want off a K-1 is box 20 code V, unrelated business taxable income. That's the line a partnership reports for tax-exempt partners, and it's what your custodian or your CPA works from when deciding whether a 990-T gets filed for the account. Ask the sponsor for a redacted prior-year K-1 showing that box, not a verbal characterization. If they won't produce one, that itself is information about the reporting they do.

The mechanism on debt-financed property: when a partnership holds property with acquisition debt, a proportional share of the income is treated as debt-financed and flows to tax-exempt partners as UBTI. Depreciation is allocated against it, which is why early-year figures on a heavily depreciated multifamily deal often come back small or negative. The exposure tends to show up on sale, when a share of the gain is also debt-financed. The averaged-debt rules for the twelve months before disposition matter there, and how they apply to a specific deal is a question for a CPA who does 990-T work.

Filings start at 1,000 dollars or more of gross UBTI in a year, and trust rates compress fast, hitting the top 37 percent bracket at roughly 16,000 dollars of taxable income for 2026. That threshold is inflation-indexed and moves every year, so pull the current figure before you model anything. Confirm current thresholds and rates with your tax professional before you model anything.

One thing your framing leaves out: your notes carry no UBIT and no filing, but they carry full credit exposure to one originator's underwriting. The syndication carries a tax cost you can compute and a sponsor risk you can't. You're choosing which of those you'd rather be wrong about, and the note concentration is the one I'd size down first.

Before the tax math, read the note documents. In an IRA the vesting has to be the custodian for the benefit of your account, and I've seen originators produce a deed of trust naming the individual because that's what their template does. Fixing that after recording is a mess, and recording practice differs by state so your custodian's boilerplate may or may not match what the county will accept.

The other document is the syndication's operating agreement. Look for whether the sponsor commits to delivering K-1s by any date, whether they'll reimburse for the 990-T prep, and whether they can add debt mid-hold without a vote. A deal at 65 percent that refinances to 75 in year three changes your UBTI profile and nobody sends you a letter about it.

sable, on the idle cash between note payoffs, ask the custodian what they pay on uninvested balances. Some pay nothing at all.
