The key insight: Working capital recycles every ~45 days (8x/year), but each DST stays under management for 2+ years. Every cycle ADDS to the cumulative AUM base. The 2% AUM fee applies to the entire growing portfolio, not just the current deployment. $25M of working capital builds a $200M+ AUM portfolio within one year, generating $4M+/yr in recurring management fees.
Each deployment cycle creates ~$25M in new DSTs that stay under management for 2+ years. Because the working capital recycles 8x/year but DSTs persist, the AUM base compounds rapidly.

Assumes earliest DSTs begin disposition at quarter 9 (start of Year 3), maintaining 2-year minimum hold. Steady state: new deployments replace dispositions, AUM plateaus at ~$400M.
$25M of working capital generates $8M/yr in recurring AUM fees at steady state. That's a 32% annual yield on the capital base, before any placement spread or disposition gains. The 8x velocity is the multiplier. No transfer fees, no acquisition fees needed. The AUM fee does all the work.
AUM grows linearly for 2 years, then plateaus as earliest DSTs begin disposition
| Period | AUM | AUM Fee Income | Less: OpEx | Net to LP | Annualized Return on $25M |
|---|---|---|---|---|---|
| Year 1 (avg AUM $125M) | $50M - $200M | $2,500K | ($500K) | $2,000K | 8.0% |
| Year 2 (avg AUM $300M) | $200M - $400M | $6,000K | ($750K) | $5,250K | 21.0%* |
| Year 3+ (steady state $400M) | $400M | $8,000K | ($1,000K) | $7,000K | 28.0%* |
*Gross to LP vehicle before promote/carry to sponsor. The 8-18% preferred return range reflects the ramp: capital providers earn ~8% in Year 1 as AUM builds, ramping toward the upper end as the fee base matures. Excess above preferred return is split per waterfall.
Unlike a traditional fund that deploys once and waits for returns, this structure has a built-in return ramp:
The 18% ceiling reflects the steady-state economics where the compounding AUM fee fully kicks in. This is not aspirational — it's the mathematical result of 8x velocity and 2% AUM.
| Fee Type | Rate | Basis | Status |
|---|---|---|---|
| AUM Management Fee | 2.0% | Total DST portfolio under management | Primary revenue driver |
| Acquisition Fee | ~0% | n/a | Virtually none |
| Transfer/Disposition Fee | 0% | n/a | None |
The 8x velocity multiplier transforms the 2% AUM fee into the equivalent of a 16% annual fee on working capital. No need for transaction fees when the AUM compounds this aggressively. Clean, simple fee structure that aligns interests: sponsor only earns when DSTs are successfully managed.
| Dimension | Traditional DST Sponsor | Optionality Capital |
|---|---|---|
| Capital Velocity | 1x | 8x annual |
| AUM per $25M Working Capital | $25M | $400M at steady state |
| Fee Income per $25M Capital | $500K/yr | $8M/yr at steady state |
| Capital Lock-up | 7 - 10 years | ~45 days per cycle |
| Transaction Fees | Heavy (acq, disp, transfer) | None. Pure AUM. |
| Exit Dependency | Market-dependent sale | Structural 1031 demand |
| LP Preferred Return | 6 - 8% | 8 - 18% (ramps with AUM) |
1031 exchange demand is structural, not cyclical. Investors MUST place capital within 180 days or face full tax liability. This creates a reliable, non-discretionary buyer pool that de-risks the exit for capital providers and ensures the recycling engine keeps turning.
