A bad tenant costs more than a vacant unit. Evictions, property damage, legal fees, and lost rent can easily run $5,000–$15,000 per incident. A tight screening process prevents nearly all of it — without running afoul of fair housing.

The Screening Framework

Four filters, in order: income, credit, rental history, background. Apply them consistently to every applicant.

1. Income (3x Rent)

Gross monthly income should be at least 3x the monthly rent. Verify with two most recent pay stubs or 2 years of tax returns for self-employed.

2. Credit Score

Minimum 620 is a common standard. Below 620, look at the story — medical collections are different than charge-offs.

3. Rental History

Call the last two landlords. Not the current one — they may lie to get a bad tenant out. The previous landlord has no incentive to mislead you.

4. Background Check

Criminal and eviction history. Use a screening service like RentPrep or TransUnion SmartMove. Fair housing requires consistent application of criteria.

Fair Housing Non-Negotiables

You cannot discriminate based on race, color, religion, national origin, sex, familial status, or disability. Many states and cities add source of income (Section 8), sexual orientation, and other protected classes.

The safest approach: written criteria, applied identically to every applicant, documented decisions.

Document Everything

Save every application, every screening report, every decision rationale. If a rejected applicant files a complaint, documentation is your defense.

Red Flags That Matter

The Application Itself

Charge a non-refundable application fee ($35–$50) that covers your screening costs. Require:

Move-in Documentation

Once you approve: photo-document every room before move-in, get a signed move-in condition report, collect first month + security deposit (plus last month in some states) via certified funds, and sign a thorough lease.

Strong screening upfront is cheaper than any eviction. Do not skip steps to fill a vacancy faster — that is how you create longer vacancies later.
