Multifamily Returns to the Fundamentals

Q3 / 03

Gross rent growth is not NOI growth; occupancy alone does not establish value.

Rental demand matters only to the extent it becomes lawful collected income after costs. Free-market and rent-stabilized units require different revenue assumptions, even in the same building.

Key Observations
  • Reconcile leases, collections and the current rent roll.
  • Separate legal rent from collectible rent.
  • Budget taxes, insurance and capital work explicitly.
  • Test refinancing without assuming cheaper debt.

Demand and cost evidence

The Comptroller's September newsletter cites August citywide market-rent growth of 5.6% year over year. Separately, RGB's April 2025–March 2026 operating-cost basket rose 5.3%, including 10.5% for insurance. Different periods and populations prevent subtracting these rates to estimate a property's NOI growth.

Underwrite collectible income

RGB Order 58 sets a 0% guideline for covered one- and two-year apartment leases commencing October 1, 2026–September 30, 2027, subject to the full order and other lawful adjustments. Preferential-rent rules also matter. Do not apply market-rent growth automatically to stabilized renewals.

Review actual taxes, insurance, repairs, payroll and utilities. NYC tax assessment is not simply purchase price multiplied by a generic rate. For Queens comparables, reconcile unit mix, condition, transit, concessions and regulatory exposure before comparing basis per unit.

A simple stress test

In this invented example, expenses rise faster in dollars than income. NOI falls, and cash after debt and capital expenditures (CapEx) declines from $130,000 to $98,000. DSCR here means NOI divided by debt service; lenders may use adjusted cash flow. Debt Yield is NOI divided by loan principal. Neither ratio guarantees approval.

What to Watch

Track collections, lawful renewals, insurance quotes, tax bills, CapEx and maturity funding gaps.

Research Notes

Scope and interpretation

The example isolates operating risk. No neighborhood Q3 NOI-growth estimate or current lending threshold is asserted.
