Bad Debt, Uncollectible Rent, and Credit Loss Reserves in Commercial Property Sizing
A certified rent roll shows contract rents, but real-world commercial properties inevitably experience tenant defaults, uncollected arrears, and bankruptcy write-offs. Lenders underwrite explicit bad debt allowances and credit loss deductions from Effective Gross Income (EGI) to ensure that debt service remains resilient even during economic downturns.

* Credit loss underwriting percentages vary based on tenant creditworthiness, lease terms, and historical property collections.
Physical Vacancy vs. Economic Credit Loss
Underwriters distinguish between physical vacancy (suites physically unleased) and economic credit loss (suites leased but failing to generate cash revenue). A building may report 95% physical occupancy, but if 8% of tenants are 90 days delinquent, the true economic occupancy is only 87%.
In sizing commercial debt, credit committees calculate Effective Gross Income (EGI) by subtracting both a baseline market vacancy factor (typically 5.0% minimum) AND an additional credit loss allowance (1.0% to 3.0%) from Gross Potential Income (GPI).
How Underwriters Analyze the Aged Accounts Receivable Ledger
During loan diligence, borrowers must provide an Aged Accounts Receivable (A/R) report categorized by delinquency aging buckets:
Delinquency Buckets and Underwriting Treatments
Current to 30 Days: Generally treated as standard collection float; credited into underwritten income.
31 to 60 Days: Scrutinized for recurring late-payment patterns; requires borrower explanation.
61 to 90 Days: High risk of lease default; income from these tenants is heavily discounted.
90+ Days Delinquent: Lenders universally exclude 90+ day delinquent tenants from underwritten NOI, treating their suites as 100% vacant for debt sizing.

Direct, transparent answers regarding underwriting standards, documentation, and process.
Underwriting Metrics
What is a credit loss reserve in commercial mortgage underwriting?
Direct Answer
A credit loss reserve is a percentage deduction (typically 1% to 3%) subtracted from a property's gross revenue to account for tenant defaults, uncollectible rent, and legal eviction expenses.
It ensures that the property's underwritten Net Operating Income realistically reflects cash collections rather than theoretical contractual rent rolls.
Delinquency Diligence
How do commercial lenders treat tenants that are 60 to 90 days past due on rent?
Direct Answer
Lenders typically exclude tenants that are 90+ days past due from underwritten Net Operating Income entirely, treating their space as vacant and subtracting their revenue from loan sizing.
Tenants with persistent 60-day delinquency are subjected to heavy collection haircut reserves or security deposit offsets.
