Good morning, NREB readers.

As always, we’re here to keep real estate professionals informed while cutting out the fluff. Let’s get right into it.

There is a number that appears regularly in housing debates:

Millions of homes across America are vacant.

The implication usually follows quickly.

If that many properties are sitting empty, why is housing still scarce? Why do we need more construction? Why can’t those homes simply be placed on the market?

The latest Census Bureau report gives us the first number and, more importantly, the context around it.

During the second quarter of 2026, the United States had an estimated 15.6 million vacant housing units.

That sounds like an enormous pool of unused supply.

But only about 1 million were classified as vacant and for sale only.

More than six million were being held off the market. Millions more were rentals, seasonal properties, or units that had already been rented or sold but were waiting for the next occupant to move in.

The national vacancy count is real.

Treating all of it as available housing inventory is not.

The Census Bureau uses a broader definition of vacancy than most buyers, sellers, or agents use in everyday conversation.

A housing unit is generally considered vacant when nobody is living there at the time of the survey, unless the normal occupants are only temporarily absent.

A vacant unit could be:

It may be a detached house, apartment, condominium, manufactured home, or another type of separate living quarter.

The term tells us that the unit was not someone’s primary occupied residence at the time of the survey.

It does not tell us that a buyer could purchase it.

The Census Bureau estimated approximately 149.5 million total housing units in the country during the second quarter.

About 133.8 million were occupied and 15.6 million were vacant.

The vacant portion was divided into several very different groups:

Those categories are estimates, and they may not add perfectly because of rounding.

There is also an important technical detail: the “for sale only” category excludes properties offered for both rent and sale. Under the Census classification, a unit being offered through both channels is included in the rental category.

So the report is not a substitute for an MLS active-listing count.

It is a picture of how the country’s entire housing stock was being used—or not used—at one moment in time.

The most revealing number may be the 6.5 million vacant units being held off the market.

That category alone was more than six times the size of the for-sale-only category.

But “held off market” does not necessarily describe a neglected house that an owner could list tomorrow.

The Census category includes:

Approximately 2 million of the off-market units were held for occasional use.

Another 1 million were temporarily occupied by people with a usual residence elsewhere.

Roughly 3.5 million fell into the broader “other” category.

The broad “other vacant” category is where the discussion becomes more complicated.

Census materials have identified common examples such as:

Some of those properties may eventually return to the market.

Others may remain outside the active housing supply for years.

A physically existing home is not automatically an economically usable home.

There may be no willing seller.

The property may need more work than its value supports.

Ownership may be unclear.

The home may be in the wrong location for current demand.

The owner may be holding it for a family member.

The property may have liens, title defects, insurance problems, code violations, or unresolved estate issues.

The distance between “vacant” and “available” can be much larger than the word suggests.

The report counted approximately 3.4 million seasonal vacant units.

That group includes housing intended for use during only part of the year, along with properties held for seasonal, recreational, or occasional occupancy.

A beach house may be empty when the Census interview occurs.

So may a cabin, ski property, desert winter home, vacation condominium, or seasonal worker unit.

That does not mean the property has been abandoned.

It may be doing exactly what the owner intends it to do.

Seasonal housing can still affect local affordability. A market with a large second-home or short-term-use population may have fewer properties available to year-round residents.

But that is a different issue from claiming that every vacant seasonal unit could immediately solve the inventory shortage.

The owner may have no intention of selling.

Even if the property entered the market, its price, location, condition, or type may not match the households most in need of housing.

National totals hide those mismatches.

Approximately 1 million vacant units had already been rented or sold but were waiting for their next occupants.

That is normal turnover.

A buyer may have closed but not moved in.

A tenant may have signed a lease that begins the following month.

A newly completed property may be waiting for occupancy.

An owner may be making final repairs between residents.

Those units appear vacant in the survey because nobody was occupying them at that moment.

They are not unused inventory waiting for a buyer.

The next resident has already been determined.

This is one reason a vacancy count can rise without producing an equal increase in homes available for purchase.

The second-quarter national rental vacancy rate was 7.3%.

The homeowner vacancy rate was only 1.2%.

The homeownership rate stood at 65%.

None of those rates was statistically different from the comparable rate one year earlier.

In other words, the new report did not show a sudden national flood of unclaimed owner-occupied housing.

The homeowner vacancy rate specifically measures the share of the homeowner inventory that is vacant and available for sale. At 1.2%, that portion of the housing stock remained relatively small.

Rental vacancy was much higher, but it also varied significantly by location.

The South had a rental vacancy rate of 9.5%, compared with 5.3% in the West, 5.9% in the Northeast, and 6.9% in the Midwest.

Principal cities had a higher rental vacancy rate than suburbs, while areas outside metropolitan regions had the lowest reported rate.

A national vacancy figure therefore cannot tell an agent whether a particular local market has too many rentals, too few listings, or a mismatch between the two.

Housing supply is not interchangeable.

A vacant apartment in one state does not help a buyer searching for a three-bedroom house near work in another.

A damaged rural property does not substitute for an entry-level home in a growing suburb.

A seasonal condominium does not necessarily serve a family looking for a year-round residence.

A luxury second home does not solve a shortage of affordable housing.

A property trapped in probate is not active inventory.

A house requiring substantial rehabilitation may exist physically while remaining financially out of reach for an ordinary financed buyer.

For housing to function as available supply, several things generally have to line up:

When those conditions do not line up, the unit may remain vacant without relieving pressure on the usable market.

None of this means vacant housing should be ignored.

Some off-market properties will eventually become listings.

A renovation will finish.

An estate will settle.

An absentee owner will decide to sell.

A landlord will stop holding a unit empty.

A second-home owner will change plans.

A city may address a long-neglected property.

An investor may rehabilitate a unit that could not previously qualify for ordinary financing.

Vacancy can represent potential future supply.

But potential supply and active inventory are not the same thing.

Converting one into the other may require time, money, legal work, owner motivation, public policy, rehabilitation, or a change in market conditions.

Agents see this distinction constantly.

A homeowner saying, “We may sell next year,” is not an active listing.

A vacant inherited home with five heirs is not an active listing.

A property under renovation is not an active listing.

A landlord waiting for rents to improve is not an active listing.

The structure exists.

The transaction does not.

Housing statistics are often used to create sweeping market narratives.

“There are no homes.”

“There are millions of empty homes.”

“Inventory has recovered.”

“Nothing is available.”

Each statement can sound true depending on which number is being used.

For agents, the better question is always:

Available to whom, in what condition, at what price, and in which location?

The total housing stock describes what physically exists.

The vacancy count describes what was unoccupied.

Active inventory describes what is currently being offered.

Months of supply reflects inventory relative to the current sales pace.

Those measures answer different questions.

Using one as a substitute for another creates bad explanations for buyers and sellers.

A market may have a meaningful number of vacant units while still having very little purchase inventory in the price range where buyers are concentrated.

Another market may have plenty of listings overall but very few that are financeable, insurable, or move-in ready.

A third may have high rental vacancy because new apartments delivered faster than tenants absorbed them, while its single-family resale market remains tight.

The headline number is rarely the full market.

Although the national total should not be mistaken for listing inventory, unusual vacancy patterns can still signal local conditions worth understanding.

A high concentration of seasonal vacancies may reveal a second-home market.

A growing number of empty rentals may indicate recent apartment construction or weakening tenant demand.

Long-term vacant houses may point to population loss, deferred maintenance, title problems, or concentrated investor ownership.

Low homeowner vacancy alongside rising active listings may mean occupied owners are listing homes while truly vacant for-sale inventory remains scarce.

Vacancy becomes useful when it is connected to the reason, property type, and location.

Without that context, it is simply a large number.

The United States had an estimated 15.6 million vacant housing units in the second quarter of 2026.

Most were not ordinary homes sitting on the market waiting for buyers.

Millions were rentals.

Millions were seasonal.

About one million had already been sold or rented.

Roughly 6.5 million were being held off the market for occasional use, temporary occupancy, repairs, personal decisions, legal circumstances, or other reasons.

Only about one million were classified as vacant and for sale only, although the Census category does not include units simultaneously offered for both rent and sale.

The vacancy count tells us how much housing was unoccupied.

It does not tell us how much housing was realistically available.

That distinction explains how the country can contain millions of empty units while buyers in many markets still struggle to find a suitable home.

Housing does not become inventory simply because nobody is sleeping there tonight.

It becomes inventory when the property, owner, condition, location, price, and market all line up well enough for someone else to move in.
