A vacancy rate is the percentage of all available units in a rental property (for example, an apartment building, hotel, or office tower) that are vacant or unoccupied at a particular moment. It is the inverse of the occupancy rate; vacancy rate + occupancy rate = 100%. Vacancy rates are used as a micro measure of a single property’s performance and as a macroeconomic indicator of market health.
Why vacancy rates matter
– For property owners and managers: vacancy rate shows how well a property rents compared with competing properties and the local market; it directly affects rental income and net operating income (NOI).
– For investors: it helps evaluate risk, forecast cash flow, and set valuation inputs (e.g., expected NOI and cap rates).
– For markets and policymakers: aggregate vacancy rates signal supply/demand balance, construction pressure, and economic strength.
– For employers: a vacancy rate can apply to open job positions (proportion of unfilled roles) and indicates hiring success, turnover, or skill shortages.
Basic calculation and example
Formula:
Vacancy rate (%) = (Number of vacant units ÷ Total number of units) × 100
Example:
An apartment building has 300 units; 30 are empty.
Vacancy rate = (30 ÷ 300) × 100 = 10%
Occupancy rate = 100% − 10% = 90%
Types and nuances of vacancy
– Vacant and rentable: units immediately available for lease.
– Turnover/turning units: recently vacated units undergoing cleaning or rehab — often counted as vacant in short-term measures.
– Unrentable units: units out of service due to repairs or renovation — some analyses exclude these from the total rentable base (use “rentable units” as denominator).
– Economic vacancy: difference between potential rent (if fully leased at market rent) and actual collected rent, expressed as a percentage of potential rent — accounts for concessions and below-market leases.
– Structural/seasonal vacancy: relates to seasonality (e.g., vacation markets) or buildings in transition (conversion, retooling).
Data sources and benchmarks
– Residential: U.S. Census Bureau reports rental vacancy rate, homeowner vacancy rate, and homeownership rate quarterly; Census also reports rents and housing characteristics.
– Commercial: brokerage and research firms (JLL, CBRE, CoStar, Cushman & Wakefield) publish periodic vacancy, rental rate, and construction pipeline reports by market and asset class.
– Local MLS, municipal housing agencies, and property managers for hyperlocal benchmarking.
How to analyze vacancy rates — practical steps
1. Define the denominator consistently
• Decide whether “total units” includes only rentable units or all physical units. For apples-to-apples comparisons, use the same definition across properties.
2. Calculate the vacancy rate
• Use the formula above. Also compute occupancy rate and track change over time.
3. Benchmark to appropriate peers
• Compare to: same asset class (multifamily, office, retail), same submarket, similar building age/quality, and similar unit mix.
• Avoid comparing apartments to office buildings, or small-town markets to major metro cores.
4. Segment and decompose
• Break vacancy down by unit type (studio/1BR/2BR), floor, building, and reason for vacancy (marketable vs in-repair). Identify hotspots and patterns.
5. Track related metrics
• Average days vacant (turnover time), net absorption (units leased minus units vacated), rent growth, concessions (free rent), effective rent (after concessions), and new supply pipeline.
6. Interpret contextually
• Consider seasonality, recent rent increases, renovations, new supply deliveries, macroeconomic conditions, and employment trends.
How investors and owners use vacancy rates — practical steps
– Due diligence
1. Request historical vacancy and turnover data (12–36 months) for the property.
2. Compare with submarket and metro vacancy and rent trends.
3. Check pipeline of new construction that could increase future vacancy.
• Modeling impact
1. Convert vacancy assumptions into revenue reductions (Potential Gross Income × (1 − Vacancy Rate)).
2. Run sensitivity scenarios (e.g., vacancy ± 2–5%) to see effect on NOI and valuation (cap rate × NOI).
3. Factor in concessions and collection loss (use economic vacancy if available).
• Asset management actions to reduce vacancy
1. Market-rate pricing: align rents to comparable units; use dynamic pricing if appropriate.
2. Improve turnover process: streamline cleaning, make-ready repairs, and faster leasing.
3. Targeted upgrades: renovate unit types with higher vacancy or low rents-per-square-foot.
4. Marketing and leasing: invest in online listings, virtual tours, broker relationships, and incentives.
5. Flexible lease terms: offer short-term leases or furnished units in demand segments.
6. Tenant retention: maintain building amenities, responsive property management, and renewal incentives.
7. Repositioning: change unit mix or convert underused commercial space to residential (where allowed).
How employers should view and act on job vacancy rates
– Calculate employer vacancy rate = (Open positions ÷ Total budgeted positions) × 100.
– Analyze alongside turnover, time-to-fill, and applicant flow.
– Practical steps to reduce job vacancies:
1. Improve recruiting channels and employer branding.
2. Examine compensation and benefits competitiveness.
3. Streamline hiring processes (reduce time-to-hire).
4. Invest in training pipelines and internal mobility to convert vacancies into promotions rather than new hires.
5. Use contingent staff or temporary contractors while filling permanent roles.
Frequency of monitoring and KPIs
– Property-level: track vacancy and related KPIs monthly; review leases and turnover quarterly.
– Market-level: use quarterly brokerage and Census updates for broader trends.
– Investment modeling: stress-test projections annually or whenever market conditions change materially.
Limitations and cautions
– A single-point vacancy snapshot can be misleading; trends and seasonal patterns matter.
– Definitions vary: confirm how other sources define vacancy before comparing (rentable units vs physical units; inclusion of units in rehab).
– Vacancy doesn’t capture quality of tenants, lease terms, or rent levels — pair vacancy metrics with rent and concessions data.
– Market-level averages can mask submarket variation; neighborhood-level analysis is important.
Takeaway checklist — what to do next
– For property owners/managers: calculate your vacancy rate, segment causes, benchmark to local peers, and implement marketing/turnover improvements.
– For investors: verify historical vacancy trends, compare to submarket metrics, and stress-test cash flows for vacancy sensitivity.
– For employers: compute open-position vacancy rate, diagnose root causes (pay, process, attraction), and act to shorten time-to-fill and improve retention.
– Use authoritative data (U.S. Census Bureau for residential, brokerage reports for commercial) and keep definitions consistent.
