Applicants ask it constantly, and landlords aren't always sure of the answer: when you screen a tenant, are you looking at TransUnion, Equifax, or Experian? Here's the straight answer and why it matters for both sides.
The short answer
There are three national credit bureaus — TransUnion, Equifax, and Experian — and any of them can be used for tenant screening. But in practice, TransUnion is the bureau most rental screening runs on. It built products specifically for the rental market, so most landlords, apartment communities, and screening platforms default to TransUnion data.
Why TransUnion dominates rental screening
Two reasons:
- ResidentScore. TransUnion offers a rental-specific score that's tuned to predict whether someone will pay rent on time — not whether they'll repay a car loan. A general FICO score wasn't designed for that; ResidentScore was. That makes it more predictive for the exact decision a landlord is making.
- Rental-market infrastructure. TransUnion built the tooling (including its SmartMove product for individual landlords) that made pulling a tenant credit report simple and FCRA-compliant. Screening platforms integrate with it because that's where the rental-grade data and workflow already live.
Equifax and Experian are fully capable bureaus and do participate in rentals — Experian's RentBureau, for instance, collects rental-payment data — but the center of gravity for tenant screening sits with TransUnion.
Which score do apartments actually look at?
Most apartment communities and landlords look at a rental-specific score (like ResidentScore) rather than the FICO number a consumer sees on a credit-card app. The scales look similar, but the model weights rent-relevant behavior more heavily, so your rental screening score can differ from the FICO you're used to. Some landlords request FICO as well; good platforms offer both. Whatever the number, experienced landlords read the underlying file — payment history, debt load, housing-related collections — not just the score. Our tenant credit check guide breaks down each section.
Does a rental credit check hurt the applicant's score?
No. A tenant screening credit pull is almost always a soft inquiry, which does not lower the applicant's credit score no matter how many times they apply. This is worth telling applicants directly — the fear of "another hard inquiry" makes good renters hesitate, and it's unfounded here.
What does this mean for choosing a screening service?
Don't over-index on the bureau name. What matters is that the service pulls from a real national bureau (not an "alternative data" aggregator), gives you a rental-relevant score, and handles the FCRA workflow — consent, identity verification, and the adverse-action letter — for you. A vague data source is a red flag; a named bureau and a rental score is what you want.
