Rental Property Vacancy Rate: How to Calculate & Reduce Vacancy

Last reviewed October 3, 2026 · U.S. statistics verified October 2026 (Census Bureau, second-quarter 2026 release)

A rental advertised at $1,650 a month looks like a $19,800-a-year asset. Then a tenant leaves, the unit takes about six weeks to clean, list and re-rent, and roughly $2,475 of that scheduled rent never arrives. Property taxes, insurance and the mortgage keep arriving anyway.

That gap between scheduled rent and collected rent is vacancy, and it belongs in every realistic rental budget. This guide shows landlords how to measure it, put a dollar figure on it, plan for it without guessing, and shorten it where the cause is within your control. It deliberately leaves the neighboring topics to their own pages: cash flow, ROI, expenses and pricing. Where vacancy touches them, you get the vacancy-specific piece plus a link.

Vacancy rate is the percentage of a property's available rental time, or available units, that no tenant occupies. Its mirror image is the occupancy rate: an 8.33% vacancy rate means 91.67% occupancy. A few related terms get blurred together, so here is how this guide uses them:

• Occupied vs. vacant: a unit is occupied while a tenant holds the lease and lives there, and vacant while it is available but has no tenant.

• Scheduled rent: what the unit would collect if leased and paid every month (often called gross potential rent).

• Actual collected rent: what really lands in your account.

• Physical vacancy: the unit is empty.

• Economic vacancy: collected rent falls short of scheduled rent for any reason, including empty months, concessions and unpaid rent (see the comparison below).

Vacancy Rate (%) = Vacant Unit Time ÷ Total Available Unit Time × 100

“Unit time” just counts units and time together. One unit available for 12 months supplies 12 unit-months; three units over a year supply 36. Vacant unit-months go on top, available unit-months on the bottom. There are two ways to measure, and mixing them up is a common source of bad numbers:

• Time-based: how long units sat empty across a period such as a quarter or year. This is the better tool for your own budget because it matches how rent is actually lost.

• Unit-based (snapshot): how many units are empty on one date, divided by total units. It is quick for multi-unit buildings, but one day can mislead: one empty unit in a four-unit building is a 25% snapshot even if it fills next week. Market statistics, including the Census Bureau's, are snapshots.

Hypothetical figures for illustration only.

Two rules keep the denominator honest. First, start counting on the date the property is genuinely ready and available to rent, not the date you bought it (row 7). Second, use the same unit top and bottom: days over days or months over months.

Suppose a landlord's two-bedroom rents for $1,375 a month. The tenant leaves and the unit takes about six weeks (treated here as 1.5 months) to re-rent. The landlord also spends about $600 on cleaning, touch-up paint and advertising. Every number is hypothetical.

That leaves roughly 84% of scheduled rent. The remaining $13,837.50 still has to cover taxes, insurance, maintenance and financing, so it is income before operating expenses, not profit. This is one hypothetical property, not a benchmark.

The direct cost is one month's rent. Table 3 shows what that does to annual income at several rent levels. For scale, the Census Bureau reported a national median asking rent of $1,531 for vacant-for-rent units in the second quarter of 2026; use your own rent in your own math.

Illustrative figures. Collected rent assumes every occupied month is paid in full.

Lost rent is only part of the bill. A vacancy also tends to bring:

• Owner-paid utilities while no one lives there

• Cleaning, touch-up repairs and re-keying

• Advertising, plus leasing or management fees where they apply

• A concession (such as a free week) if you need to fill the unit faster

• Lost ancillary income such as parking, pet rent or laundry

Enter your own numbers below. The pre-filled values match the worked example above so you can check the math, and they are placeholders rather than recommendations.

These are estimates, not predictions. Results show income before operating expenses and financing. Actual vacancy varies with property type, location, tenant demand, pricing, seasonality and market conditions, so no vacancy figure here should be treated as a standard.

A vacancy allowance (sometimes called a vacancy factor) is the amount, usually a percentage of scheduled rent, that you subtract in a projection to reflect rent you do not expect to collect. The related terms are easy to confuse:

• Vacancy rate: a measurement of what happened (or a market statistic).

• Vacancy allowance: an assumption you choose for next year.

• Vacancy loss: the dollar result, actual or estimated.

• Operating expenses: costs you pay. Vacancy is not a bill; it reduces income before expenses are counted. Some landlords still carry a “vacancy reserve” budget line so cash is on hand, which works as long as the loss isn't counted twice.

• Cash flow: what remains after everything. The cash-flow guide shows where the allowance sits in the full calculation; this page is about choosing a defensible number.

No universal “correct” percentage exists, and any rule claiming one should be treated cautiously. The better approach is to anchor to evidence and then adjust for your property.

An official reference point. The U.S. Census Bureau's Housing Vacancy Survey put the national rental vacancy rate at 7.3% in the second quarter of 2026 (released July 28, 2026), compared with 7.0% a year earlier, a difference the Bureau described as not statistically significant. The same release shows how much the figure moves by place (all second quarter 2026):

• By area: principal cities 8.0%, suburbs 6.9%, outside metropolitan areas 5.8%

• By region: Northeast 5.9%, Midwest 6.9%, South 9.5%, West 5.3%

Read those numbers carefully before borrowing them. They cover all rental housing, from apartment buildings to single-family homes, not your specific property type. They are a snapshot of units vacant for rent, not the time-based loss on one property. They are survey estimates with margins of error, and they are not seasonally adjusted. The next release, covering the third quarter, is scheduled for October 28, 2026. Source: U.S. Census Bureau, Housing Vacancy Survey, July 28, 2026.

Use market data as context, then refine with local evidence: your own history, how many days comparable listings stay up, and what a local property manager sees. Your assumption should move with:

• Location and local rental demand

• Property type and who it realistically suits (near a campus versus a family neighborhood, for example)

• Seasonality and local employment conditions

• Your rent relative to comparable properties

• Property condition and amenities

• Management quality and marketing reach

• How often tenants turn over

Physical vacancy asks whether the unit is empty. Economic vacancy asks how much of the rent you could have collected you did not collect, for any reason. Lenders and professional operators track the two separately; one multifamily underwriting form from Fannie Mae, for example, lists vacancy loss, concessions and bad debt on separate lines.

Example: a unit scheduled at $1,500 a month is occupied all year, but the landlord gave one free month and the tenant is $900 behind. Gross potential rent is $18,000; collected rent is $18,000 − $1,500 − $900 = $15,600. Physical vacancy is 0%, yet economic vacancy is $2,400 ÷ $18,000 = 13.33%. Late-payment losses are a collections issue covered in how to collect rent from tenants.

Some causes sit with you; others are the market's doing. Separating them stops you from “fixing” a problem you didn't have, such as cutting rent when the real issue was a weak listing.

Some causes are shared. A market slowdown doesn't change the fact that you decide how to respond to it.

None of these guarantees full occupancy or a specific improvement. They are the levers landlords actually have.

Rent above what comparable units actually achieve is a frequent reason a unit sits. Building comps, adjusting for features and testing a price are covered in the pricing guide. The vacancy-specific advice: decide in advance what level of interest would make you re-check comps, and diagnose the listing and condition before cutting rent by reflex.

Lead with strong photos and put price, availability and policies where they can't be missed. An accurate listing also screens out mismatched prospects who would otherwise use up showing slots. The advertising guide covers headlines, photo order and tracking.

Match channels to the property and likely renter, keep price and dates identical everywhere, and take filled listings down promptly. See rental listing sites for where to post.

Interest cools while prospects wait, and several of the units they contact compete with yours. Response time is one of the few levers fully in your hands. Check messages on a predictable schedule, offer concrete showing times and keep answers accurate. No specific response window is guaranteed to win a tenant.

Turnover is a chain: move-out → inspection → repairs → cleaning → photos → listing → showings → screening → lease → move-in. The vacancy clock runs from the last day of paid rent until the new rent starts, so the goal is to overlap steps instead of queuing them:

• Where your lease and local entry-notice rules allow, begin listing preparation once notice is given rather than after keys are returned.

• Use notes from a mid-tenancy check to line up likely repairs before the final walkthrough. The inspection checklist and move-out checklist keep it organized.

• Pre-book cleaners and contractors so work starts the day after move-out.

• Have the lease agreement and move-in checklist ready so approval turns into move-in without a gap.

Problems found during a tenancy can be fixed while rent is still arriving. Problems discovered at move-out delay showings. The maintenance checklist shows what to catch early.

Write your criteria down in advance, apply them consistently, and have your reporting process ready before applications arrive. Don't skip steps to fill faster, because a short vacancy can be traded for a larger loss later. The tenant screening guide covers the process.

What you record, you can improve. Log vacancy days and lost rent for every turnover alongside your other numbers; rental property bookkeeping covers the record-keeping and the management guide covers routines if you self-manage. Metrics are listed in the tracking section below.

Turnover is the event of one tenancy ending and another beginning. Vacancy is the period in between when the property is not producing normal rent. They are related but not the same, and a landlord can have plenty of turnover with almost no vacancy.

Timeline example (hypothetical): The lease ends March 31. The move-out inspection and repairs run April 1–8, while the listing goes live April 6. An application is approved April 14, the lease is signed, and the new tenant's lease starts April 20. Vacancy was April 1–19, or 19 days, even though turnover touched every step. Had listing waited until repairs finished, each later step would have shifted by the same number of days. In a second case, Tenant A's lease ends April 30 and Tenant B's begins May 1: turnover happened, vacancy was zero.

Tenancy length matters as much as gap length. A one-month gap after every 12-month tenancy is 1 ÷ 13 ≈ 7.7% of time; after every 24-month tenancy it is 1 ÷ 25 = 4%. That is why good tenants who renew are a vacancy strategy in themselves.

To see the sensitivity, take a hypothetical rental at $1,500 a month ($18,000 scheduled) with $13,200 a year of costs that don't change with occupancy, such as taxes, insurance and loan payments. Changing only the vacancy assumption:

• No vacancy: $18,000 − $13,200 = $4,800

• 1 month vacant: $16,500 − $13,200 = $3,300

• 2.5 months vacant: $14,250 − $13,200 = $1,050

• 4 months vacant: $12,000 − $13,200 = −$1,200

The same property flips from comfortable to negative on the vacancy assumption alone. This is simplified: it ignores costs that vary with collected rent, like a percentage-based management fee. The full calculation is in the rental property cash-flow guide.

Vacancy reduces effective income, which reduces net operating income (NOI), which feeds every return metric built on NOI. As a hypothetical: on a $200,000 property, each $1,000 of NOI lost to vacancy lowers the cap rate by 0.5 percentage points ($1,000 ÷ $200,000). Two empty months on $1,500 rent is $3,000, or 1.5 points. Because financing costs don't shrink with vacancy, cash-on-cash return can fall proportionally even more. The formulas and calculator are in the rental property ROI guide.

Many costs continue whether or not anyone is paying rent: property taxes, insurance, owner-paid utilities, HOA or association charges where they apply, financing costs, and basic maintenance. Vacancy then adds its own spending on advertising, cleaning and turnover repairs. The full category list is on the rental property expenses page.

On the tax side, IRS guidance says expenses incurred while a property is vacant but available for rent may be deductible, while lost rental income during vacancy is not (see IRS Publication 527). Whether a property counts as held for rent depends on the facts, so see rental property tax deductions and confirm your situation with a tax professional.

Vacancy is never perfectly predictable, so scenario analysis beats a single guess:

1. Start with annual scheduled rent.

2. Gather evidence: your own past gaps, local days-to-lease, and the Census context above.

3. Build a lower-vacancy, base and higher-vacancy case. Some investors treat the higher case as their conservative planning case.

4. Add turnover cost for each expected vacancy.

5. Hold a cash reserve sized to the higher case, so a long gap is an inconvenience rather than a crisis.

Annual scheduled rent is $19,200. None of these cases is “correct”; they bracket a plausible range.

Judge trends, not single months. One quick re-rent or one long gap says little; a rolling 12 months or several turnovers say more. Define your clock consistently: vacancy days run from the last paid-through date of the old tenancy to the rent-start date of the new one.

• Assuming 12 months of rent every year

• Using a generic percentage without checking the local market

• Ignoring turnover time between move-out and rent start

• Pricing solely to avoid vacancy and leaving income on the table

• Dropping rent immediately instead of diagnosing the cause

• Ignoring property condition until the unit is empty

• Waiting until the property is vacant to begin preparing

• Not tracking actual vacancy days

• Confusing physical vacancy with economic vacancy

• Overlooking recurring patterns, such as vacancy always landing in the same season

• Failing to separate market-driven vacancy from landlord-controlled vacancy

This page is general educational information for landlords, not personalized financial, tax, accounting or legal advice. Vacancy depends on your market, property and timing, and landlord-tenant rules, entry-notice requirements and tax treatment vary by jurisdiction and change over time. Every dollar figure and percentage in the examples, tables and calculator is hypothetical and illustrative, not a projection, benchmark or guarantee. Where possible, base your assumptions on your own records and local market evidence, and confirm tax questions with a qualified tax preparer or the IRS.
