Short answer: In 2025 Mark looked at analysis suggesting tariffs act like a consumption tax that weighs most on lower- and middle-income households. Those customers already tend to have shorter storage stays, which means more turnover and marketing cost. The lasting lesson for him: pay closer attention to income levels and stability in a trade area.
The chain Mark describes #
- Price increases on everyday goods cut into discretionary spending, especially for lower- and middle-income households.
- In Mark’s experience those households already have shorter average stays.
- Shorter stays mean more turnover and higher marketing costs to re-rent units.
- In lease-up, a facility may rent the same unit two or three times before stabilizing, stretching the timeline into the loan’s interest-only period.
How it changed his trade-area analysis #
- He looks for trade areas with higher rent levels and higher median income than before.
- Median income by zip code or county can be too broad, so he and Inner Circle members use a subscription data tool’s neighborhood-level income index to check whether most of a trade area sits in the upper income tiers.
The wider lesson #
Mark’s takeaway from studying investors who saw the 2008 crisis coming: follow where money is actually moving, not media narratives. He also notes that how foreign investors view U.S. economic stability can influence long-term interest rates, which matter to every leveraged storage deal.
Trade policy changes often. This answer reflects Mark’s 2025 analysis, not a current forecast.
