What Is a Good Occupancy Rate for an Apartment Building?

Read Time: 7 min

Occupancy is one of the first numbers anyone looks at when evaluating an apartment building, and one of the most commonly misread. A property that is 98% occupied sounds better than one that is 92% occupied, but that headline figure can hide below-market rents, heavy concessions, or tenants who are not actually paying. For passive investors reviewing a syndication, knowing what a healthy occupancy rate looks like, and which version of the number you are being shown, is basic but essential diligence.

Physical Occupancy vs. Economic Occupancy

Physical Occupancy

Physical occupancy is the simple version: the share of units with a tenant living in them. A 50-unit building with 48 occupied units is 96% physically occupied. It tells you how full the building is, but nothing about whether those tenants are paying full rent, or paying at all.

Economic Occupancy

Economic occupancy measures the rent a property actually collects as a share of the rent it would collect if every unit were leased at market rate and every tenant paid in full. It captures the gaps physical occupancy misses: vacant units, rents below market (often called loss-to-lease), move-in concessions, and bad debt from tenants who are behind. Economic occupancy is almost always lower than physical occupancy, and it is the number that actually drives net operating income.

Illustrative 50-Unit Building	Monthly Amount
Gross potential rent (50 units at $1,400 market rent)	$70,000
Vacancy (2 empty units)	($2,800)
Loss-to-lease (in-place rents below market)	($2,100)
Concessions and bad debt	($1,400)
Rent actually collected	$63,700
Physical occupancy	96%
Economic occupancy	91%

The figures above are an illustration, not data from a specific property, but the gap between the two percentages is typical. A sponsor who only reports physical occupancy is giving you the more flattering half of the picture.

What the Current Market Data Shows

Context matters, because "good" depends on what the surrounding market is doing. According to Yardi Matrix's August 2026 Multifamily National Report, national multifamily occupancy held at 94.2% in July, down 0.5% from a year earlier. Chicago, by comparison, posted occupancy of 96.0%, with only 2.5% of its housing stock in the lease-up phase.

The same report shows how new supply pulls occupancy down in specific markets. Charlotte had 11.6% of its inventory in lease-up, Austin 10.9%, Phoenix 9.8%, and Nashville 8.9%, and those markets were among the ones still posting negative rent growth. When a large share of a market's apartments are brand-new buildings competing for tenants with concessions, older properties nearby feel that pressure in both occupancy and rent. A 93% occupied building in a heavily supplied Sun Belt market and a 93% occupied building in a supply-constrained Midwest market are telling you different things.

General Benchmarks for Physical Occupancy

There is no single correct number, but the ranges below reflect how many operators and lenders tend to think about a stabilized apartment building. Treat them as rules of thumb, not hard standards.

Physical Occupancy	What It Usually Signals
97% to 100%	Strong demand, but rents may be below market and worth testing
93% to 96%	A healthy range for most stabilized properties
90% to 92%	Worth a closer look at the market, management, or unit condition
Below 90%	A problem to explain, or a renovation or lease-up underway

Why Higher Isn't Always Better

A building that has sat at 99% or 100% occupancy for years is not necessarily well run. Sustained full occupancy can mean rents have fallen behind the market, which is good for tenants and bad for the property's income. Some vacancy is normal and even healthy, since units turn over, get cleaned and repaired, and re-lease at current rates. For a value-add investor, a property with persistently full occupancy and below-market rents can be an opportunity, because there is room to bring rents up as leases roll and units are renovated. The relevant question is never just how full a building is, but how full it is at what rent.

How Property Class Affects the Picture

Newer Class A buildings often run slightly lower physical occupancy because they compete directly with new construction and tend to lean on concessions during lease-up. Class B properties, the workforce housing that sits in the middle of the market, frequently run steady occupancy because they serve a large pool of renters priced out of new construction but looking for a well-maintained home. Class C properties can show high physical occupancy alongside weaker economic occupancy, since collections and bad debt tend to be the bigger challenge at that end of the market. This is one reason economic occupancy matters more as you move down the quality spectrum.

How Occupancy Shows Up in Underwriting

In a pro forma, occupancy appears as a vacancy and credit loss assumption, usually a percentage deducted from gross potential rent. A careful sponsor bases that assumption on the property's own trailing performance and on what comparable buildings in the same submarket actually achieve, not on the best month in the property's recent history. Lenders care about this too. Many agency lenders expect a property to show sustained occupancy around 90% before they will treat it as stabilized for permanent financing, and debt service coverage ratios are calculated on income that depends directly on occupancy and collections.

Occupancy During a Value-Add Business Plan

A temporary dip in occupancy is a normal part of most value-add plans. When units are taken offline for renovation, or when a new owner replaces non-paying tenants, physical occupancy can fall for a period before recovering at higher rents. What matters for an investor is whether the business plan anticipated that dip, whether the reserves and timeline account for it, and whether the property is tracking back toward stabilization on schedule. An occupancy decline that was planned and budgeted for is very different from one that was not.

Look at the Trend, Not a Single Month

A single occupancy figure is a snapshot, and snapshots can be timed. A seller can push occupancy up in the months before a sale with aggressive concessions or looser tenant screening, and the trailing collections will tell a different story than the rent roll. When you review a deal, ask for occupancy and collections over at least the trailing twelve months, and look at whether the trend is stable, improving, or slipping. A building that has held steady at 94% for a year is often a more reliable starting point than one that jumped to 98% in the last quarter before listing.

How Red Brick Equity Thinks About Occupancy

We look at both physical and economic occupancy on every acquisition, and we pay close attention to the gap between them, since that gap usually tells us more about a building's real condition and management than the headline number does. Our focus on supply-constrained Chicago and Midwest submarkets is partly about occupancy stability: markets with limited new construction tend to see less concession pressure and steadier demand from workforce renters. We underwrite vacancy and credit loss from the property's actual trailing performance and local comparables, and we report occupancy and collections to our investors in the quarterly performance presentation that accompanies each distribution, so they can see how a property is tracking against the plan.

Frequently Asked Questions

What is a good occupancy rate for an apartment building?

For a stabilized property, physical occupancy in the range of roughly 93% to 96% is generally considered healthy, though the right number depends on the local market, the property class, and how rents compare to market.

What is the difference between physical and economic occupancy?

Physical occupancy is the share of units with tenants in them. Economic occupancy is the share of potential rent actually collected, after accounting for vacancy, below-market rents, concessions, and unpaid rent. Economic occupancy is the better measure of how a property is performing financially.

Is 100% occupancy a good sign?

Not always. Sustained full occupancy can indicate rents that are below market. A small amount of vacancy from normal turnover is expected, and it gives an owner the chance to re-lease units at current rates.

Why does occupancy drop during a value-add renovation?

Units taken offline for renovation, and turnover as leases end, temporarily reduce the number of occupied units. A well-planned business plan accounts for this dip with reserves and a realistic timeline for re-leasing renovated units at higher rents.

What occupancy number should I ask a sponsor for?

Ask for both physical and economic occupancy, ideally on a trailing basis, along with how the property compares to similar buildings in its submarket. Asking for both tells you more than either number alone.
