The difference between screening well and screening badly is almost entirely whether you decided the rules before you saw the applicant.
General information for landlords, not legal advice. Federal, state and local fair housing law applies to screening criteria, and some jurisdictions restrict credit or criminal-history screening. Confirm your local rules or consult an attorney before publishing requirements.

Requirements written after applications arrive are requirements written about people. That is both the fair housing risk and the practical one: it is how landlords end up making inconsistent decisions they cannot explain six months later.
Write the standard first. Publish it with the listing. Then the decision is arithmetic.
The five components of a workable standard
Income: the multiple you require, whether it is gross or net, and how you treat multiple applicants and non-wage income.
Documentation: exactly which documents you accept for each income type, including alternatives for self-employed and benefit income.
Rental history: how many years, whether you contact prior landlords, and what disqualifies.
Identity: what identification you accept.
Exceptions: what an applicant who misses a threshold can do instead — most commonly a guarantor or additional deposit where lawful.
Write requirements as tests, not impressions
"Stable employment" is not a requirement; it is an opinion. "Six months of continuous documented income at 3x monthly rent" is a requirement. Every line should be something a stranger reading your file could verify the same way you did.
Offer alternate routes to the same standard
Accepting bank statements from a self-employed applicant instead of pay stubs is not lowering your standard — it is measuring the same thing with the evidence that applicant's work produces. Refusing to do so screens on employment type rather than ability to pay, and eliminates a large share of otherwise qualified renters.
Publish, apply, record
Show the requirements on the listing and at the top of the application. Apply them to every applicant in the order received. Keep a record of what each applicant provided and how the decision was reached. That record is your defence and your training material.
Frequently asked questions
Can I set my own screening criteria as a landlord?
Generally yes, provided the criteria are lawful, applied consistently, and do not discriminate against protected classes. Some jurisdictions additionally restrict how credit history, criminal history, or source of income may be used.
Do I have to publish my requirements?
Some jurisdictions require written screening criteria to be disclosed. Even where not required, publishing them reduces unqualified applications and makes your decisions easier to explain.
What if an applicant almost meets the requirement?
Decide the exception policy in advance — for example, a guarantor at a higher income multiple — and offer it to every applicant in the same position.
