THE MARKET · INDUSTRIAL WORKSPACES
Demand has outrun supply.
Traditional developers build for large logistics users, leaving small businesses with few places to grow. Small bay industrial (space under 50,000 square feet for trades, contractors, and light industrial users) has some of the lowest vacancy in the sector. Demand from these businesses keeps rising while new supply lags behind. That gap is where Mainstreet invests.
Estimated small bay industrial demand each year that current supply does not meet.

Mainstreet's investment opportunities are generally open to accredited investors, as defined by the SEC. However, eligibility can vary by offering, so each one's materials list its own requirements. Request investor information and our team will walk you through whether an opportunity fits.
-
Minimums and hold periods depend on the offering and are matched to the development and stabilization timeline of each property. The full terms for each investment are in its offering documents, which may be requested from our team.
-
Investments may generate distributions, subject to fund performance and management discretion. When distributions are made, they're paid [quarterly] to investors in proportion to their ownership, and each one comes with a report on property performance. Timing and amounts are not guaranteed and vary by investment.
-
Mainstreet's investment opportunities are sponsored by Spark Invests, LLC ("Spark" or the "Sponsor"), the capital formation and financing arm of Mainstreet. As sponsor, Spark may earn [an acquisition or development fee, an asset management fee, and a share of profits after investors receive their preferred return]. We also co-invest alongside our investors, so our interests are aligned from day one. Each offering's documents disclose its full fee structure.
