Verifying tenant references and running personal checks are your strongest defenses against problem renters. A glowing credit score means little if a previous landlord warns you about property damage or chronic late payments. Here's what to ask and how to spot red flags before signing a lease.
Why References Matter More Than You Think
References reveal what background checks can't: behavioral patterns, communication issues, and actual lease violations. A tenant might have a clean criminal record but still have evicted themselves from three apartments in two years. Previous landlords and personal references provide context that numbers alone can't deliver.
The difference between a smooth tenancy and a costly eviction often hinges on information you gather directly from someone who's actually lived through it with the applicant.
What to Ask Previous Landlords
When contacting prior landlords, move beyond surface-level questions. Ask specific, behavioral questions that expose patterns:
- How many days late were rent payments, and how often? Look for consistency. One late payment might be circumstance; chronic lateness is character.
- Were there noise complaints, property damage, or lease violations? Ask for specifics—did they cause $200 in damages or $2,000?
- Would you rent to them again? A hesitant answer or long pause is telling.
- How did they handle maintenance requests and communication? Unresponsive tenants create friction fast.
- Did they give proper notice when leaving? Disappearing without notice suggests unreliability.
- Were there any issues with guests or occupancy? Subletting or unauthorized residents indicate disregard for lease terms.
Aim for at least two prior landlords. If they've only rented once, get a personal reference who's known them for years instead.
Evaluating Personal References Strategically
Personal references are less reliable than landlord checks, but they still matter. Avoid accepting a reference from someone in the same household or immediate family—their bias is too high.
Strong personal references come from:
- Employers or supervisors (demonstrates stability and financial responsibility)
- Long-time friends or colleagues (five+ years)
- Community leaders (clergy, coaches, teachers—people with professional accountability)
When contacting personal references, ask about reliability, financial responsibility, conflict resolution, and whether they've seen the applicant handle stress or setbacks. Does this person follow through on commitments? How do they respond when things go wrong?
Red Flags During Reference Checks
Watch for these warning signs:
- References that are hard to reach – Applicants sometimes provide fake numbers or unresponsive contacts. Follow up multiple times before dismissing a reference.
- Rehearsed, short answers – "He's great" without detail suggests the reference wasn't genuine.
- References who speak vaguely about recent history – "I knew him years ago" doesn't tell you who they are now.
- Negative language about minor issues – One landlord mentioning a single late payment is context; two or three mentioning chronic lateness is a pattern.
- Refusal to answer specific questions – A prior landlord who won't discuss rent payment history is suspicious.
Combining References with Background Checks
References work best alongside formal tenant screening. While background checks verify criminal history, eviction records, and credit, references provide the narrative. A background check catches an eviction; a landlord reference explains whether it was one bad year or ongoing negligence.
Expect formal screening services to cost $25–$75 per applicant and take 24–48 hours. Many Property Management providers now bundle reference verification with background checks, saving time and creating a unified report.

Documenting Your Findings
Keep written records of all reference calls. Note the date, who you spoke with, their relationship to the applicant, and specific answers. This protects you legally and helps if you need to justify a rejection later. Document reasons for approval too—consistency matters if a tenant later disputes your decision.
Frequently Asked Questions
Q: What should I do if a previous landlord won't return my calls? Reach out at least twice over a week, including different times of day and methods (phone, email). If they're genuinely unreachable, note the attempt in your file and rely more heavily on other references.
Q: Can I reject a tenant based solely on what a reference says? Yes, but document it. Rejection based on a landlord reporting chronic late payments or eviction is defensible; rejection based on vague character concerns is harder to justify legally.
Q: Should I charge a screening fee to applicants? Most landlords do ($25–$50), which covers your background check and reference-checking time. Disclose the fee upfront and make it clear what's included.
