How to Screen a Tenant

The highest-return hour in property management — and the one place where consistency matters more than judgement.

$60 vs $12,000

What screening costs against what a single bad tenancy costs.

Written criteria first

The single most important step happens before any applicant appears: decide your standards, write them down, publish them with the listing, and then apply them to every applicant in the same way and in the order received. This does two jobs at once. It is how fair-housing compliance actually works in practice, and it is what stops you from talking yourself into a marginal applicant at the end of a slow month.

Criterion	A common standard	Note
Income	Gross monthly income ≥ 3× rent	Verified from source, not from a supplied document.
Credit	A minimum score, plus no unpaid housing debt	Publish the number. Medical collections are often excluded — decide and write it down.
Rental history	Two years, no lease violations, no money owed	The single most predictive item on the list.
Employment	Stable, verified with the employer	Self-employed applicants supply returns or bank statements instead.
Eviction and criminal history	Per applicable law	Rules vary sharply by state and city — look-back limits, individualised assessment requirements, and outright bans on some inquiries.
Occupancy	Consistent with local occupancy standards	Set it by bedroom count and local code, never by family composition.

Fair housing is not a formality

Federal law protects race, colour, national origin, religion, sex, familial status and disability, and many states and cities add more — source of income, age, marital status, sexual orientation and others. The protection you have as a landlord is consistency: identical written criteria, applied in the same order to every applicant, with a record of each decision. Advertising, showing and screening are all covered. Where you are unsure of a local rule, get advice — this article is not legal advice.

The process

1Publish the criteria with the listing. It deters unqualified applicants, saves everyone time, and creates a record that the standard existed before the applicant did.
2Pre-screen on the phone with the same three or four questions: move-in date, occupants, income range, pets. Ask everyone the same questions.
3Show the unit and let them see it properly. Applicants who never visit in person are a recognised pattern in rental fraud.
4Take a complete application from every adult who will live there, with ID and consent to run reports.
5Run credit, eviction and background checks through a proper tenant screening service, and follow the adverse-action requirements if you decline someone based on a report.
6Verify independently — see below. This is where the value is.
7Decide in order and document it, then move promptly. Good applicants have other options.

The four verifications that matter

Verify	How	What you are catching
Income	Employer contact using a number you looked up yourself, plus two or three recent pay records or bank deposits.	Fabricated pay stubs are cheap and common. The employer's own number is the check.
The current landlord	Call them — and ask whether they own the property. Cross-check the address against public records.	The current landlord may want them gone. The previous one has no such incentive, which is why you call both.
The previous landlord	Same call, less bias.	The most honest reference you will get.
Identity	Photo ID matched to the application and to the credit file.	Application fraud, and applications submitted in someone else's name.

The single best question

Ask a former landlord: “Would you rent to them again?” It is open, it is not a judgement call about a protected characteristic, and the pause before the answer tells you more than the answer does.

What the hour is worth

Cost of screening versus cost of getting it wrong

Screening reports and time: ≈ $60
Eviction — filing, attorney, court time: $3,000 – $5,000
Lost rent during the process (3–6 months): $6,300 – $12,600
Damage beyond the deposit: $1,000 – $5,000
Turnover after regaining possession: $5,025

One bad tenancy costs 150–300× what screening does.

And the loss is not only the money. An eviction consumes months of attention, and in slow jurisdictions the timeline is measured in seasons rather than weeks. Against that, the pressure to fill a vacancy quickly is almost always the more expensive instinct — one extra week of vacancy costs about $485 on this property.

Red flags worth naming

Signal	Why it matters
Urgency to move in immediately, with cash	The most reliable predictor of a problem. Legitimate applicants can wait three days for verification.
Offering many months of rent up front	Sometimes legitimate for a self-employed or foreign applicant; often an attempt to buy past screening. Verify anyway — and check local rules on advance rent limits.
Reluctance to give the current landlord's contact	Occasionally explicable. Always worth pursuing.
A story that changes between the call and the application	Inconsistency is the cheapest signal there is.
Never viewing the property in person	Common in rental scams and in applicants who will not stay.
Income exactly at the threshold with no cushion	Not disqualifying — but it is the profile most sensitive to one bad month.

Screening well is also the cheapest way to reduce turnover cost: a tenant who stays four years instead of one removes three turnovers, which is worth more than most rent increases you will ever negotiate. See how much to raise the rent for the other half of that trade.

Frequently asked questions

What should I look for when screening a tenant?

Verified income of about three times the rent, a clean two-year rental history with no money owed, stable employment, and a credit profile that meets a standard you set in writing before you saw the application. Rental history from a previous landlord is generally the most predictive item.

What income should I require from a tenant?

Gross monthly income of three times the rent is the most common standard. Whatever multiple you choose, publish it with the listing and apply it identically to every applicant, and verify it with the employer rather than relying on documents the applicant supplies.

Can I reject a tenant for a criminal record?

The rules vary substantially by state and city, with look-back limits, requirements for individualised assessment, and in some places prohibitions on asking at all. Blanket exclusions have been challenged as discriminatory. Check your local rules and take advice before setting a policy.

How much does tenant screening cost?

Around $35 to $75 per applicant for credit, eviction and background reports, often passed on as an application fee where local law permits. Set against an eviction and lost rent that can total $10,000 to $15,000, it is the highest-return hour in property management.
