Screening Tenants: Credit, Income and References

By the Prizm P.M. team at STS Automatic LLC · Last reviewed September 18, 2026 · 8 min read

Screening is the highest-leverage hour in the whole rental cycle. A bad tenant costs months of lost rent, repairs and legal fees; a good one makes the property nearly invisible in your week. The goal is not to find a perfect applicant — it is to run the same defensible process on every applicant and let the results decide.

Write your criteria down before you advertise

Written criteria are the single best protection against both bad decisions and discrimination claims. Publish them with the listing and apply them in order. A workable set:

Verifiable gross income of at least 3x the monthly rent (2.5x in expensive markets).
A minimum credit score, commonly 600–680, with stated exceptions such as a larger deposit or a guarantor.
No unpaid rental collections or eviction judgments within the past five to seven years.
Positive references from the two most recent landlords.
Occupancy limits consistent with local code.

Never screen on race, color, religion, sex, national origin, familial status or disability — the federal protected classes — and check your state and city, which often add more, including source of income.

Income and employment verification

Ask for two to three recent pay stubs, or for self-employed applicants, the most recent tax return plus two to three months of bank statements. Confirm employment directly with the employer's HR line rather than a phone number on the application. Documents are easy to fabricate; a phone call is not.

Count only income you can verify. A promised raise, an expected bonus, or a roommate not on the lease are not income.

Credit and background checks

Run these through a screening service where the applicant verifies their own identity with the bureau, so their Social Security number never lands in your inbox. Read the whole report rather than the score: a 640 with perfect rent history and one old medical collection is a far better risk than a 700 with three recent utility collections.

Landlord references — ask better questions

Current landlords sometimes give a glowing reference to move a problem along, so always reach the previous landlord too. Useful questions:

What were the move-in and move-out dates, and what was the rent?
Was rent paid on time each month? How many late payments?
Was the full security deposit returned? If not, why?
Were there complaints from neighbors or lease violations?
Would you rent to them again?

That last question, followed by silence, is the most informative ten seconds of the whole process.

Red flags worth pausing on

Pressure to skip steps or move in immediately.
An offer to pay several months up front in place of screening.
Gaps in rental history the applicant will not explain.
Names or dates that do not match between the application and the report.
Refusal to provide a previous landlord's contact information.

None of these is automatically disqualifying. Each is a reason to verify more, not to decide faster.

Deciding, documenting and declining

Score every applicant against the same written criteria and keep the file: application, verification notes, report summary and the reason for the decision. If you decline based on information in a consumer report, U.S. federal law requires an adverse action notice telling the applicant which agency supplied it and that they may obtain a free copy and dispute it.

Keep declined applications for the period your state requires. The file is what turns "I treated everyone the same" from a claim into evidence.

Frequently asked questions

How long should screening take?

Two to four business days is realistic: reports come back in minutes, references and employers take longer. Tell applicants the timeline up front so nobody feels strung along.

Can I charge an application fee?

Usually yes, commonly $30–$55 to cover the screening cost, but several states cap it or require you to refund the unused portion. Check locally.

Should I accept a guarantor?

A guarantor is a reasonable accommodation for a thin credit file, especially for students or new arrivals. Screen the guarantor with the same criteria and get their signature on the lease.
