Multifamily Payroll Underwriting: Hours, Not a Percent

Published November 12, 2026

Onsite payroll is one of the largest controllable lines on an apartment operating statement, and it is one of the lines most often entered as a percentage. A 200-unit property staffed with a manager, an assistant, two maintenance technicians, and a part-time porter carries roughly $240,000 of base wages before a dollar of employer cost is added on top. Per the Bureau of Labor Statistics (BLS) Employer Costs for Employee Compensation release covering June 2026, published September 9, 2026, benefits accounted for about 30% of total compensation in real estate and rental and leasing — $13.19 of a $43.53 hourly total — which is roughly 43% layered on top of wages alone.

A model that plugs payroll at 7% of effective gross income has not underwritten any of that. It has underwritten a ratio that happened to hold at a different property, in a different state, with a different benefit plan.

Why Multifamily Payroll Underwriting Starts With Hours

Multifamily payroll underwriting works from the bottom up because the cost is driven by scheduled hours and statutory loads, neither of which moves with revenue. Rent can fall 5% and the manager still works a 40-hour week. The percent-of-revenue plug embeds the opposite assumption, which is why it tends to understate the line in a soft-revenue year and overstate it in a strong one.

The build has three parts. First, the staffing plan: positions, hours, and whether coverage is seven days or five. Second, wages by role, taken from local pay for that role rather than from the seller's register, since a long-tenured maintenance supervisor and a replacement hire are rarely the same cost. Third, the load — employer Federal Insurance Contributions Act (FICA) taxes, federal and state unemployment, workers' compensation at the applicable class code, and whatever share of health and retirement benefits the employer actually pays.

The third part is where the plug fails most reliably. Wages are visible on a register; the load is assembled from several places and is easy to leave at a round 15%, which covers payroll taxes and roughly nothing else.

What the 2026 Labor Cost Data Shows

Sourced facts first, interpretation after.

• Per the BLS Employer Costs for Employee Compensation release for June 2026 (published September 9, 2026): total compensation in real estate and rental and leasing averaged $43.53 per hour worked, of which wages and salaries were $30.35 (about 70%) and benefits $13.19 (about 30%).
• Per the same release, private industry overall averaged $46.89 per hour, split $32.82 in wages and $14.07 in benefits.
• Per the BLS Employment Cost Index for the 12 months ending September 2026 (published October 30, 2026): private industry total compensation rose 3.4%, wages and salaries 3.1%, and benefit costs 3.9%.
• Per CRE Daily's October 15, 2026 report on the National Apartment Association's (NAA) Dollar of Rent study: operating expenses averaged about $8,213 per unit in 2025, up 4.6% from $7,848 in 2024, while monthly revenue per unit rose 2.7% to about $1,545. Payroll took about 7 cents of each rent dollar; the study reports no payroll dollar figure per unit.
• Per NAA's "Where Does a Dollar of Rent Go?" (February 24, 2026, on 2024 data from more than 16,000 properties): payroll expense per unit has risen nearly 20% since 2021.

What this could mean, read as an interpretation rather than a forecast: benefit costs have been growing faster than wages in the BLS series, so a load factor carried forward from an older model may understate the current cost even where the wage assumption still holds. And because the NAA study reports payroll as a share of rent rather than as a per-unit cost, a comparison against it measures the ratio a plug already assumes rather than the hours and loads underneath it. These are national averages — individual properties vary by state, staffing model, and benefit design.

A Worked Example: A 200-Unit Build Against the Plug

Illustrative figures throughout. A 200-unit Class B property in a secondary market, effective gross income of approximately $3.60M, five-day office coverage with weekend leasing by appointment.

The wage base underneath the build is five positions: a community manager and a maintenance supervisor at 2,080 hours each, an assistant manager and a maintenance technician at 2,080 hours each, and a porter at roughly half time — approximately $243,000 of base wages in total, at hourly rates that would need to be set against local pay for each role. The two load scenarios bracket a real range. A property whose staff largely decline employer health coverage may run nearer 25% to 30%; the BLS-implied 43% reflects an industry average that includes employers with richer plans.

Take the midpoint of the build, roughly $333,000, against the 7% plug at $252,000. The gap is approximately $81,000 of annual Net Operating Income (NOI). Capitalized at 5.5%, that is close to $1.5M of value on a property priced near $36M — about $7,400 per unit.

The financing effect is larger than the value effect when sizing is constrained by coverage rather than by leverage. With the 10-year Treasury at 5.00% (per the Federal Reserve H.15 release dated October 27, 2026, for October 26), an illustrative 6.0% coupon on 30-year amortization produces a debt constant near 7.19%. At a 1.25x Debt Service Coverage Ratio (DSCR) floor:

• NOI of $1.98M on the plug supports roughly $22.0M of proceeds.
• NOI of $1.90M on the build supports roughly $21.1M.

An $81,000 line item moves the loan by approximately $900,000 — about 11 times the annual expense, because the coverage test capitalizes it at the constant rather than at the cap rate. Rate quotes and sizing tests change frequently, so verify current terms directly with a lender.

The Payroll Lines That Get Double-Counted or Missed

Several items sit at the boundary of the payroll line, and each one can be counted twice or not at all.

The management fee. The fee generally pays for off-site supervision and the accounting platform, not for the onsite team. Where a seller's statement runs the manager's salary inside the fee, lifting a market fee onto a staffing build double counts; where the reverse is true, the fee looks low and the payroll line looks complete. The mobile home park (MHP) management fee and payroll build runs into the same ambiguity from the MHP side.

Capitalized maintenance payroll. Technician hours spent on unit turns and capital projects are sometimes charged below the line, which flatters NOI without reducing the cash cost. A payroll figure that reconciles to the register but not to the general ledger usually has hours sitting in capital expenditures.

Contract-service substitution. Outsourcing landscaping, turns, or after-hours maintenance lowers payroll and raises contract services by a similar or larger amount. Comparing a property's payroll per unit against a benchmark without comparing the combined figure can read a staffing choice as an efficiency.

Bonus, commission, and overtime. Leasing bonuses move with lease volume, so they rise in exactly the year a value-add program raises turnover. Overtime for after-hours calls tends to track the age of the mechanical systems rather than the staffing plan.

The employee apartment. A discounted or free onsite unit is an occupancy and revenue effect rather than a payroll cost, yet it is frequently modeled in both places or in neither. The same reconciliation discipline that normalizing a messy T-12 applies to the revenue side applies here; for the mechanics underneath these lines, the Net Operating Income and T-12 statement references cover the arithmetic.

Where This Framing Breaks

The honest counter-case is that an hours-and-load build is only as good as its wage assumptions, and those are harder to source than the loads. The BLS load factor is a published national figure; local pay for a maintenance technician in a specific submarket generally is not, and an underwriter guessing high on five positions can manufacture an $80,000 problem that does not exist. Where a seller's payroll register is available and the staffing model is being retained, the register is often the better starting point, with the build used to test it rather than to replace it.

Scale cuts against the method as well. A 200-unit property carries a full staffing complement whether it is modeled carefully or not, but a 60-unit property may share a manager across three assets, and allocating that cost by door is an accounting convention rather than an observable fact. Portfolio buyers in particular can run genuine staffing leverage that a property-level build cannot see, which means the build may overstate cost for them while understating it for a single-asset buyer of the same deal.

There is also a limit to how much precision the output deserves. Payroll works out to roughly 15% to 17% of a typical apartment operating expense load on the NAA figures above, an estimate derived by dividing payroll's 7 cents per rent dollar by total operating expenses of about 44 cents ($8,213 against roughly $18,540 of annual revenue), with the range reflecting rounding in the cents, and the load factor inside it is an estimate layered on a wage estimate. Carrying that to the dollar invites false confidence in a line that could reasonably be stated as a range. Multifamily payroll underwriting earns its keep by establishing an order of magnitude the plug cannot produce, not by being exact.

The Underwriting Takeaway

Payroll underwritten as a percentage of revenue is a ratio borrowed from another property. Built from positions, hours, local wages, and a load factor grounded in current data, it becomes a line that can be defended in a lender conversation and tested against the seller's register.

The number to watch is not the expense but its multiple. A coverage-constrained loan capitalizes a recurring expense at the debt constant, which in the example above turned $81,000 a year into roughly $900,000 of proceeds — the same asymmetry that makes insurance and the year-two property tax reset worth more diligence than their share of the expense stack suggests.
