Pricing illiquidity when buying into a single asset storage LLC as a minority LP

A small syndication built around one self storage facility, say 310 units plus 22 outdoor RV and boat spaces, where the sponsor already owns the asset and is selling down 40 percent of the equity to fund a canopy build and a gate and access system replacement, is a useful case for thinking through illiquid preferred equity positions. Say the purchase basis was $4.1M in 2021, current appraisal $4.75M, debt $2.6M fixed through 2028. A $265,000 check for roughly 12 percent of the equity, with a 7 percent cumulative non-compounding pref and a 70/30 waterfall after pref, no lookback, no catch up, is a fairly standard structure on paper. What tends to look good: boring, stable occupancy in the high 80s to low 90s over several years, and outdoor RV or boat spaces that carry near zero maintenance cost. What tends to look worse on closer read is the operating agreement. Total transfer restrictions, a right of first refusal to the sponsor priced by the sponsor's own appraiser, a 60 day cure, and no put right ever, effectively mean the position has no defined exit. A sponsor's verbal estimate of a seven to ten year hold isn't the same as paper that says forever. The real question in a structure like this is whether the pref rate and asset quality compensate for a position that genuinely cannot be sold on the investor's own timeline. Pushing for a valuation formula in the ROFR instead of sponsor's-appraiser, or a two appraiser plus tiebreaker mechanism, improves the terms but still isn't a market. If distributions get suspended for a capex build and demand stays thin, the investor is holding an unsellable position with a growing accrued balance and no way out, and that scenario deserves as much weight as the base case before committing capital.
