The short answer
Compare occupancy, leasing, collections and costs using the same property, period and calculation rules. Keep the underlying counts, unresolved records and next action with every result.

Define the measurement before calculating
A key performance indicator (KPI) answers a specific operating question. Choose a small set you can reproduce from dated records rather than collecting percentages without a decision to make. These are original review definitions for a manual worksheet, not a promise that every Rentari report calculates them in this form.
For each measure record the property/unit set, start and end dates or snapshot date, numerator, denominator, source records, accounting basis where relevant, exclusions, data cutoff and reviewer. Count a household tenancy, unit, lease event or room consistently; roommates are not automatically separate acquired tenancies. Keep newly added, sold, unavailable and overlapping units visible rather than quietly changing the denominator.
A zero denominator, missing source or unresolved classification is not a zero-percent result. Mark the measure not applicable or unresolved, explain why, and retain the raw counts for follow-up.
Use financial statements and reconciliation for profit, cash and liabilities. A KPI summary supplements those records; it does not establish a tax treatment, compliance result or future return.
Separate physical occupancy, vacancy and revenue
Physical occupancy asks whether the home is occupied under your documented definition. A signed future lease, payment receipt or temporarily absent resident needs the appropriate status; none alone establishes every day's physical occupancy. When a status is unknown, show that count and leave a complete percentage unresolved rather than silently treating it as vacant.
| Measure | Numerator and denominator | Important distinction |
|---|---|---|
| Snapshot physical occupancy | Confirmed occupied eligible units ÷ all eligible units at the stated instant × 100. | Document inventory exclusions and unknown units. Only a fully classified occupied/vacant set makes vacancy its complement. |
| Snapshot vacancy | Confirmed vacant eligible units ÷ the same eligible units at the same instant × 100. | Identify available, undergoing work and held-out units separately; do not hide a renovation by changing scope between periods. |
| Period occupancy and vacancy | Occupied unit-days, or vacant unit-days, ÷ eligible rental unit-days in the period × 100. | Each included unit contributes its eligible days. Preserve missing status days and acquisition/disposal boundaries. |
| Rental revenue realization | Defined rental revenue after the stated vacancy/concession/credit treatment ÷ supported gross potential rent for the same inventory and period × 100. | This monetary measure differs from physical occupancy. State cash or accrual basis and treatment of bad debt; label estimated potential rents and avoid deducting an adjustment twice. |
Reports labeled economic occupancy or economic vacancy can use different income and adjustment rules. Preserve their formula rather than assuming they mean occupied units or this worksheet's revenue realization. A cash version must identify which charge periods receipts belong to and its collection cutoff.
Census Housing Vacancy Survey definitions distinguish occupied, vacant-for-rent, rented-awaiting-occupancy and off-market units. Its rental inventory and survey method are not automatically your portfolio denominator. Keep external figures' observation period and definitions; a national historical rate is not this property's target.
Keep renewal and turnover cohorts distinct
For a renewal review, start with the tenancies reaching a defined renewal decision or expiry in the period. Record renewed, ending, continuing periodically, excluded and unresolved outcomes. Define how a continuation counts, which decisions are eligible and the cutoff used to resolve them.
- Renewal rate: confirmed renewals or defined continuations ÷ eligible tenancies in that same decision cohort × 100. Show the raw counts and unresolved decisions; do not present an incomplete cohort as a final result.
- Unique-unit turnover: eligible units with at least one actual move-out during the period ÷ average eligible units in the period × 100. Derive that average consistently, such as eligible unit-days ÷ days in the period.
- Move-out event rate: total move-out events ÷ the same average unit count. Label repeated turnovers separately; an event rate can exceed one event per unit.
Renewal and turnover percentages are not automatically complements: their cohorts and event dates differ. A transfer, early departure, new acquisition or repeated tenancy can affect them differently. Record the reason where available without inferring resident satisfaction, payment reliability or causation from one percentage.
Measure completed leasing time and open vacancy
Choose the clock before comparing listings. Time from first accurate public availability to a fully signed agreement is different from move-out-to-move-in vacancy or repair time before advertising. Record the actual start, signed date, move-in date, paused exposure and why each interval exists.
For a completed leasing cohort, add the days from the defined start to signing for each included new tenancy, then divide by the number of those completed tenancies. Do not divide all portfolio vacant days by unrelated new leases. Show the cohort count, individual durations and longest durations alongside the mean; a few leases can move a small portfolio's average sharply.
List still-open vacancies with their age at the cutoff and readiness or marketing blockers. Excluding them from completed leasing time can make results look faster while the hardest vacancies remain unresolved. Keep total vacant unit-days as a separate period measure. Compare dated market evidence and the actual offer before changing rent or advertising.
Match collections to the charges being measured
Define a charge cohort, such as lawful net rent charges due in a named month. Record approved credits and corrections, excluding refundable deposits and unrelated fees. For a collection percentage, divide verified receipts allocated to those charges, net of relevant refunds/reversals, by the cohort's net rent due. State the through-date for receipts and show unresolved allocation separately.
A payment received this month against old arrears does not collect this month's charge. Pending, processing, returned or disputed payments require review; a status or bank-feed import is not sufficient evidence of settled rent. Verify outside payments and avoid duplicating them with a later imported receipt. Keep fees, resident receipts and agency assistance separately attributable where applicable.
Review zero or negative denominators and incomplete inputs as not applicable or unresolved, with an explanation. A receipt total divided by scheduled rent can answer a different question; label it precisely. Use the bank-record reconciliation guide before relying on cash totals.
Define rent, growth, acquisition and maintenance costs
| Measure | Calculation | Review alongside it |
|---|---|---|
| Average contracted monthly rent | Sum of monthly contractual rents in the dated eligible lease set ÷ that set's tenancy/unit count. | Separate asking rent, concessions, actual receipts and different utilities/furnishings. State how partial periods and shared-unit contracts are handled. |
| Revenue growth | (Current-period revenue − matched prior-period revenue) ÷ prior-period revenue × 100. | Same duration, property set, basis and revenue categories; separately explain acquisitions, seasonality and one-time items. Zero/negative baselines need another comparison. |
| Acquisition cost per new tenancy | Allocated costs of the declared acquisition cohort ÷ confirmed new tenancies attributed to it. | State whether advertising alone or also staff time, photography, leasing and screening costs are included. Distinguish inquiries and roommates from tenancies; document attribution and costs whose outcome is pending. |
| Maintenance cost per unit | Defined maintenance costs for the period ÷ average eligible units for that period. | Include declared labor/material allocations consistently. Separate routine work, turnover, major capital work and reimbursements; show unpaid commitments if excluded by cash basis. |
| Net operating income | Defined operating income − defined operating expenses for the same period and accounting basis. | Keep financing, capital spending, owner transfers and refundable funds distinct. Profit, spendable cash and taxable income differ. |
Fannie Mae's August 2024 Form 4254 definitions provide a specific multifamily servicing example of potential rent, separate vacancy/concessions/bad debt, operating income and expenses. Its normalization and financing rules are not universal instructions for every owner's internal or tax report. Retain the definition required by the actual lender when preparing its statement.
Investigate the work and invoices behind a cost change. There is no universal maintenance percentage or renewal target established here, and delaying necessary safety work to improve a KPI is not an operating plan. Keep repair-versus-capital records for qualified tax review and use the repair response guide for operational follow-through.
Read an original example without mixing denominators
This fictional arithmetic example uses four eligible homes throughout a 30-day period. All status days are known: 90 occupied unit-days and 30 vacant unit-days out of 120 eligible unit-days. Period occupancy is 75%; vacancy is 25%. A final-day snapshot is a separate calculation.
Net rent due for that period is $4,500. Verified net receipts allocated to those charges total $4,050 through the stated cutoff: collection is 90%. Another $600 received against prior arrears is kept outside this cohort. If supported gross potential rent for the period is $6,000, the defined cash revenue realization is 67.5%, despite 75% physical occupancy. These figures answer different questions; none is a forecast or customer result.
Two tenancies reach a renewal decision, one renews and one remains unresolved. Record one confirmed renewal and one pending outcome rather than calling a completed 50% retention result. If two completed leasing intervals are 10 and 20 days, their mean is 15 days; a third vacancy still open at 40 days must remain visible beside that average.
Use current reports as evidence, then review the gaps
Rentari's report guide explains choosing a report, period/property filters, coverage and available downloads. Report definitions and access requirements differ. Existing rent, vacancy, leases-ending and financial reports can supply useful recorded evidence; do not assume a report title proves physical history, settled funds or the complete cohort used here.
Rentari has occupancy and collection views, but their definitions can differ from this worksheet. The visual occupancy trend uses recorded active leases covering any part of a month against the current unit inventory; it does not reconstruct confirmed occupied unit-days or historical inventory. A rent-pipeline collection measure can include payments still processing alongside settled amounts, while the visual collection trend groups recorded paid charges by their due month. Preserve the view, filters and review cutoff, and reconcile the underlying records before treating either figure as verified cash or comparing it with a differently defined percentage.
Use the reviewed rent-roll export to inspect its date, inventory, columns and Coverage notes. Current code derives occupancy from available lease/unit records. Missing dated occupancy, overlapping leases or changed historical balances need confirmation; room/bed inventory does not establish corresponding leases. Recorded deposit liabilities are not verified bank balances.
Keep a review worksheet with one row per metric: formula, period/scope, raw inputs, exclusions, missing records, result or unresolved status, comparison period, possible explanation, next action, responsible person and review date. The IRS recordkeeping guidance supports retaining source documents for income and expenses. Keep sensitive resident/application records in appropriately restricted locations rather than putting names into a shared KPI summary.
Compare your own matched periods first. If using a benchmark, preserve its publisher, geography, rental type, sample, observation/publication dates and formula. A changed KPI does not prove an explanation; investigate the records and test a bounded next action. Rentari provides software and written guides, not a management service or a guarantee that these calculations automatically appear in a dashboard.

Common questions
Is economic occupancy the same as physical occupancy?
No. Physical occupancy counts occupied units or unit-days; an economic measure uses defined revenue and potential-rent inputs. Preserve the formula, accounting basis, adjustments and period.
Are renewal and turnover rates complements?
Not necessarily. Renewal decisions and move-out events can use different cohorts, dates and denominators. Show raw counts, unresolved decisions and repeated events.
Can an open vacancy be omitted from leasing-time review?
Keep open vacancies visible with their age and blockers. A completed-lease average alone leaves the unresolved cases out and can appear faster while they remain vacant.
Does a payment marked processing count as collected rent?
Confirm actual receipts and settlement evidence, allocate them to the measured charges and account for returns, refunds and outside payments. A processing label does not prove collected cash.
Does this guide promise an automatic KPI dashboard?
No. This is a written review method. Inspect each actual report's scope, inputs and coverage; resolve missing records and calculate any additional measures from verified evidence.
