Notes: Long-term capital gains (LTCG) taxes use simplified 2025 MFJ brackets in isolation (0%/15%/20%). NIIT (3.8%) and state taxes are excluded. The 5% return is treated as a pre-tax effective return in both scenarios for apples-to-apples comparison. In reality, DST cash flows and tax character can differ; this is a planning aid, not tax advice.
