This is a useful way to surface where to look, especially because vacancy is one of those numbers that can be both highly informative and dangerously persuasive depending on what sits underneath it.
The 2% in 28134 is obviously the headline, but the part I’d want to understand is whether we’re looking at a strong market condition, a temporary market state, or the visible result of several different forces arriving at the same number.
Vacancy by itself tells us that units are occupied. It doesn’t necessarily tell us why.
For example, I’d want to know how that 2% has moved over time. If the ZIP was at 7%, then 5%, then 3%, then 2%, that tightening trajectory matters. If it has bounced between 2% and 8% depending on seasonality, property type, or a relatively small rental denominator, that tells us something different.
Then I’d start separating the demand side from the supply side.
On the demand side: household formation, migration, employment growth, income growth, renter household growth, school-zone demand, commute patterns, and whether people are choosing the ZIP or simply accepting it because neighboring areas have become unaffordable.
On the supply side: permits, completions, multifamily deliveries, build-to-rent inventory, investor-owned single-family inventory, conversion of owner-occupied homes into rentals, and anything already entitled but not yet delivered.
That distinction matters because low vacancy created by durable demand is not the same thing as low vacancy created by temporarily constrained supply.
I’d also want to pair vacancy with rent behavior. If vacancy is compressing while effective rents are increasing, concessions are disappearing, and days-to-lease are falling, the signals reinforce one another. If vacancy is low but rent growth is flat and concessions are increasing, there may be something else happening beneath the surface.
Then comes the investor-specific layer, which is where I think these numbers become genuinely useful.
The question isn’t really “Which ZIP has the lowest vacancy?”
It’s closer to:
Where is the spread between market strength and acquisition cost still favorable?
A 2% vacancy market can still be a mediocre investment if everyone already knows it is a 2% vacancy market and that expectation has been fully capitalized into the purchase price.
Meanwhile, a 6% or 7% vacancy ZIP that is tightening, adding households, absorbing new supply well, and still trading at a materially better basis may actually offer the stronger forward return.
That’s why I tend to think of these metrics less as rankings and more as signals.
Vacancy tells you where something interesting may be happening.
Then you start asking whether the condition is durable, what is causing it, whether it is accelerating or decelerating, what the market has already priced in, and whether the property-level economics allow you to capture any of that advantage.
Taxes, insurance, maintenance, financing, management and purchase price obviously matter, as you pointed out. I’d add one more variable to that list: direction.
Two properties can have identical economics today and very different economics three years from now because one sits inside a market whose underlying conditions are strengthening while the other sits inside one whose current numbers simply happen to look good.
That’s what would make 28134 interesting to me.
Not just the 2%.
The question is whether the 2% is the beginning, middle, or end of the story.
