The IOS land grab is on. Here's how to find what isn't listed.

The window

The numbers first. IOS is a roughly $218 billion asset class growing near 9% a year. Institutional capital now drives 35 to 45% of acquisitions, up from about 25 to 30% four years ago, and funds targeting the space are closing oversubscribed. Supply is frozen: most municipalities downzoned outdoor storage decades ago, so the parcels that carry the right zoning are grandfathered and irreplaceable. And more than half the inventory is still owned by local operators who have never thought of their lot as an institutional asset.

Capital flooding in, supply that cannot grow, ownership that has to turn over. Consolidation is not coming. It is underway, and the window where off-market sourcing beats auction pricing lasts exactly as long as it takes everyone else to get good at it.

Find what isn't listed

The problem: this asset class cannot be searched. The value is land, not building, and the best sites have never been listed because their owners are not selling yet. So the search starts from the land itself. In MAIA, it runs in minutes:

Zoning and size. Industrial or heavy-commercial, two to ten acres. Hundreds of thousands of parcels become a few thousand.

Yard ratio. The defining trait of IOS is open, unimproved yard relative to building coverage. Footprints give the improved area, the parcel gives the total, imagery confirms the rest is usable yard, not trees or slope. A few thousand becomes a few hundred.

Access. Distance to an interchange, freight-corridor proximity, and whether a truck can actually get in and turn around.

Ownership. Owner-occupied operating business versus passive investor. Mailing address versus site address, entity name, hold period. Together they rank the list. The sites everyone can see trade at auction; the sites only you can see trade at your basis.

Contacts. An LLC with a registered-agent address is not a phone call. No source resolves every entity; skip-trace waterfalls get the hit rate high enough that outreach is worth running.

Price it right

IOS comps quote in $/SF of yard, and the denominator is fiction: deed area includes the pond, the setbacks, the buffer. Everyone normalizes to usable area, and nobody agrees what usable means. Net out the truck circulation path or count it? Gravel at full rate or discounted? Two sophisticated buyers underwrite the same site and land 20% apart on basis because they disagree about where the drive aisle ends. MAIA measures yard the same way it built your list, applies your house rules as parameters, and re-normalizes every comp identically, with the polygon behind every number inspectable. Apples to apples in a market trading apples to fruit salad.

More like this

Two more searches open up from there. Hand MAIA your portfolio and ask what else looks like it; your best sites become the query. Or find aggregation: adjacent qualifying parcels under different owners, or scattered parcels under one LLC. A portfolio acquisition hiding in the assessor data, one conversation instead of five.

The filter is the asset

A list is a snapshot. The filter is the asset: your thesis, saved, re-running as ownership turns over and new parcels qualify. And every number in it opens to the imagery and records behind it, because a list you cannot check is a list you will not act on.

The institutions have the capital. The local owners have the land. Whoever holds the map in between is going to have a very good decade.
