Key Takeaways
- Economic vacancy (physical occupancy minus collection losses) is the true income metric—not physical occupancy alone.
- Tenant screening costs $30-$50 per applicant but prevents $3,000-$8,000 per eviction in losses.
- Track screening acceptance rates: 30-70% is the target range balancing quality with applicant pool size.
- Budget collection losses at 2-8% of GPR depending on property class and tenant demographics.
Credit risk in real estate investing refers to the risk that tenants will fail to pay rent or default on their lease obligations. For multifamily properties, credit risk is diversified across many tenants, but concentrated credit risk (a single commercial tenant or anchor tenant) can threaten the entire investment. This lesson covers credit risk assessment, tenant screening, and collection loss management.
Assessing Credit Risk at the Property Level
Credit risk assessment begins with the rent roll analysis during acquisition due diligence. Key metrics: current occupancy rate (physical and economic), collection rate (actual collected rent / billed rent—target above 95%), tenant credit score distribution (if available), lease expiration schedule (concentrated expirations increase credit risk), tenant income-to-rent ratios (tenants paying more than 35% of income are higher default risk), and delinquency history (percentage of tenants with late payments in the past 12 months). A property with 95% physical occupancy but only 88% collection rate has significant credit risk that may not be apparent from the occupancy number alone. Economic vacancy (occupancy minus collections) is the true income metric.
Tenant Screening as Risk Mitigation
Rigorous tenant screening is the most cost-effective credit risk mitigation tool. Minimum screening criteria should include: credit score (minimum 600-650 for Class B properties, 550-600 for Class C), income verification (minimum 2.5-3x monthly rent), criminal background check, eviction history (no evictions in the past 5 years), employment verification, and landlord references (at least 2 prior landlords). The screening cost ($30-$50 per applicant) is negligible compared to the cost of a bad tenant: $3,000-$8,000 in lost rent, legal fees, and turnover costs per eviction. Track screening acceptance rates—if you are accepting more than 70% of applicants, criteria may be too loose. If accepting fewer than 30%, criteria may be too restrictive and are limiting your applicant pool.
Collection Loss Management
Even with excellent screening, some tenants will default. A structured collection process minimizes losses. Day 1: rent is due. Day 2-3: friendly reminder (text, email, or door notice). Day 5: formal late notice with late fee assessment. Day 10: pay-or-quit notice (statutory notice required before eviction in most states). Day 15-20: file for eviction if no payment or payment arrangement. Throughout this process: document everything, communicate in writing, and never accept partial payment without a written agreement (partial payment acceptance can restart the eviction timeline in some jurisdictions). Budget for collection losses in the pro forma: 2-3% of GPR for Class A properties, 3-5% for Class B, 5-8% for Class C. These percentages include both vacancy and credit loss.

Common Mistakes to Avoid
Combining physical vacancy and credit loss into a single vacancy assumption
Consequence: Obscures the distinct drivers and mitigation strategies for each risk, preventing targeted management
Correction: Model physical vacancy and credit loss separately—physical vacancy responds to marketing and pricing, credit loss responds to screening and collections
Relying solely on credit scores for tenant screening
Consequence: Credit scores may not reflect current ability to pay; a high-scoring applicant with recent income loss can become a collection problem
Correction: Verify current income (pay stubs, tax returns), require 3:1 income-to-rent ratio, and contact prior landlords in addition to running credit checks
