Empirical Analysis & Findings
## Valuation Science: Commercial Capitalization Rate Mechanics
A property's capitalization rate (Cap Rate) represents the unlevered return on investment based on normalized net operating income:
```
Valuation = Realized Underwritten NOI / Capitalization Rate
```
### 1. Cap Rate Spread Across Commercial Property Sectors
Capitalization rates fluctuate according to tenant creditworthiness, lease duration, and macro Treasury yields:
| Property Sector & Tier | Q3 2026 Benchmark Cap Rate | Target NOI Operating Margin | 10-Year Treasury Yield Spread|
|:------------------------------|:----------------------------:|:----------------------------:|:----------------------------:|
| Class A Multifamily (Sunbelt) | 5.25% - 5.60% | 62.0% | +125 to +160 bps |
| Industrial Logistics / Big Box| 5.10% - 5.45% | 78.5% | +110 to +145 bps |
| Single-Tenant Net Lease (STNL)| 5.75% - 6.20% | 92.0% | +175 to +220 bps |
| CBD High-Rise Office | 7.50% - 8.75% | 54.0% | +350 to +475 bps |
### 2. Underwriting Exit Yield Expansion
Assuming static capitalization rates across a 7-year hold creates dangerous valuation inflation. Seasoned sponsors project exit yields expanding by at least 50 basis points to cushion against refinancing debt market shocks.

Frequently Asked Questions
What is the standard basis point spread between going-in and exit cap rates?
Institutional real estate underwriting mandates an exit cap rate expansion of 5 to 10 basis points per year of holding period (e.g., a 25 to 50 bps expansion on a 5-year hold).
What items must be subtracted from Gross Operating Income to compute Underwritten NOI?
Underwriters deduct operating expenses (management fees, property tax, insurance, utilities, maintenance) plus an above-the-line capital replacement reserve ($250 to $400 per unit).
