A bad tenant costs more than a vacant unit. Evictions in most US states cost $3,000–$7,000 in legal fees, lost rent, and property damage — and in tenant-friendly jurisdictions like California, New York, or Ontario, the process can take six months or longer. The most effective way to avoid that outcome is a rigorous, consistent, and legally compliant screening process applied to every applicant without exception.
This guide covers every component of tenant screening — from writing your criteria before advertising the unit to the exact questions you cannot legally ask.
Step 1: Write Your Screening Criteria First
Before you list the property, document your minimum screening standards in writing. This protects you legally by demonstrating you applied consistent criteria to all applicants — not criteria that changed based on who was applying. Your written criteria should cover income requirements, credit score minimums, rental history standards, and your pet policy.
Step 2: Income Verification
The standard income requirement is that gross monthly income equals at least 2.5–3× the monthly rent. A $1,800/month apartment should require $4,500–$5,400/month in verifiable gross income.
For self-employed applicants, bank statements and tax returns are more reliable than income claims. Request 3–6 months of statements and look for consistent deposits rather than one large recent transfer.
Step 3: Credit Check
A credit report reveals payment history, outstanding debts, collections, bankruptcies, and prior evictions (which may appear as civil judgments). Require written consent from the applicant before pulling credit — this is legally required under the Fair Credit Reporting Act (FCRA).
Credit Score Benchmarks
- 680+: Strong applicant — low risk indicator
- 620–679: Acceptable with strong income and rental history
- 580–619: Higher risk — consider requiring larger deposit if local law permits
- Below 580: Decline or require co-signer depending on full picture
Look beyond the score at the underlying data. A 620 score from one medical collection is very different from a 620 score with multiple missed rent payments and active collections.
Step 4: Rental History Verification
Contact previous landlords directly — not just the references the applicant provides. Ask the previous landlord's name and contact, then look up the property and contact the owner independently. Applicants sometimes list a friend as a fake landlord reference.
Questions to Ask Previous Landlords
- Did they pay rent on time consistently?
- Did they give proper notice before moving out?
- Did they leave the property in good condition?
- Were there any lease violations or complaints from neighbors?
- Would you rent to them again?
The "Would you rent again?" question is the most revealing. A landlord who hesitates, qualifies their answer, or says "I'd rather not say" is giving you important information without stating it directly.
Step 5: Employment Verification
Call the employer listed on the application. Confirm the applicant is currently employed there and ask for their title and start date. You cannot ask about salary (the applicant's pay stubs cover that), but you can confirm employment status. For self-employed applicants, verify their business registration or ask for client contracts.
What You Cannot Ask or Consider
Fair Housing Warning: Federal Fair Housing Act and state/local laws prohibit discrimination based on race, color, national origin, religion, sex, familial status, and disability. Many states and cities add additional protected classes — source of income, sexual orientation, age, immigration status, and more. Never ask about these categories, and never make screening decisions based on them. Apply your written criteria identically to every applicant.
Red Flags That Warrant Declining
- Prior eviction judgment on record
- Previous landlord won't give a clear positive reference
- Inconsistent income documentation or refusal to provide it
- Multiple recent collections or active bankruptcies
- Requests to skip the application process or move in immediately without screening
- Hostile or aggressive behavior during the application process
Trust the process, not your gut. Apply every criterion consistently and document your decisions. If you decline an applicant, keep your written screening criteria and the applicant's file for at least 3 years in case of a fair housing complaint.
