Lease Comparable Analysis

**Lease Comparable Analysis** is a fundamental valuation method used to determine the prevailing market rent for a specific commercial property by examining recently executed leases at similar, competing properties within the same submarket. Appraisers, underwriters, and brokers adjust these comparable leases—often called "lease comps"—for differences in location, size, condition, tenant improvement allowances, and lease terms. By establishing an accurate baseline for market rent, this analysis helps professionals project the potential gross income of a subject property. It is a critical component of the income capitalization approach, ensuring that the underwritten cash flows reflect realistic market conditions rather than relying solely on the property's historical performance or the sponsor's optimistic projections.

When sizing a commercial mortgage for an office building with significant upcoming tenant rollover, a mortgage broker will utilize a **Lease Comparable Analysis** to justify the underwritten pro forma income to a prospective lender. If the subject property currently has tenants paying below-market rents, the broker will present recent lease comps from similar Class B office buildings nearby to demonstrate that the space can be re-leased at higher rates. The lender’s underwriter will then review this analysis to verify that the projected rental income is achievable. This process directly influences the loan sizing, as the underwriter will cap the projected net operating income based on these verified market rents to determine the maximum allowable loan amount and ensure sufficient debt service coverage.

A **Lease Comparable Analysis** is crucial for commercial real estate professionals because it grounds property valuation and loan underwriting in empirical, real-time market data. For lenders, it mitigates the risk of over-leveraging a property based on inflated, above-market rents currently in place, or overly optimistic sponsor projections. If a property's contract rents are significantly higher than market comps, the lender knows to underwrite to the lower market rate to account for future rollover risk. For brokers, providing a well-researched lease comp analysis is essential for maximizing loan proceeds and securing favorable terms. It builds credibility with capital providers by demonstrating a thorough understanding of the local submarket dynamics, ultimately facilitating smoother loan approvals and more accurate asset pricing.
