How to Choose a Good Tenant and Avoid Late Payers

Choosing the right tenant is probably the most important decision you will make as a landlord. A good screening process considerably reduces the risk of missed payments, disputes and wear and tear on the property, while a rushed choice can turn into months of headaches and financial losses. Here we explain, step by step, how to choose a tenant using objective, verifiable criteria, without falling into discrimination or basing decisions solely on a "good impression."

Why tenant screening matters so much

A poor screening process is usually the source of most rental problems: overdue rent, damage to the property, conflicts with neighbors or, in the worst case, long and costly eviction proceedings. When you understand how to choose a tenant systematically, you reduce uncertainty and protect both your income stream and the value of your property.

The best approach is to treat every application with the same objective criteria: verifiable ability to pay, track record as a tenant and overall stability. This not only protects you legally by avoiding discriminatory decisions, it also gives you a clear framework for comparing several candidates fairly.

If you have doubts about the right rental price before listing your property, you can rely on tools like the rent calculator to set realistic expectations from the start.

Documents you should request

Before moving forward with any candidate, ask for a standard package of documents. This lets you compare applications consistently and spot inconsistencies early.

A well-structured contract also protects both parties. You can review a reference model in our article on the lease agreement before drafting your own.

How to verify income and ability to pay

A commonly used rule of thumb in the market is that monthly rent should not exceed roughly one third of the tenant's net income. This ratio is only a general guideline; adjust it based on the candidate's profile and the context of your city.

• Request at least two or three months of proof of income to rule out one-time fluctuations.
• Check that what the candidate states matches the documents provided. If the candidate says they work at a company but the pay stubs don't match, that's a sign to dig deeper.
• Consider a guarantor (aval) or a security deposit when income is variable (freelancers, self-employed business owners) or hard to document formally.
• Ask for bank references or employment letters as additional support when the case warrants it.

References and background

Contacting previous landlords directly is one of the most revealing steps in the process. Ask specifically about payment punctuality, care of the property, relationship with neighbors and the reason for leaving. If the candidate refuses to provide this information or only offers references from relatives, treat it as a red flag.

It's also a good idea to look for basic matches: the name on the ID should match the name on the proof of income, and contact information (phone, email) should be consistent throughout the entire process.

Red flags to avoid

No single sign is conclusive on its own, but several combined should prompt you to dig deeper before moving forward. Also remember that, as a landlord, you have legal obligations to the tenant once the contract is signed; it's wise to learn them in advance by reviewing tenant rights in Mexico.

How to formalize the relationship once you've chosen

Once you've decided on a candidate, put everything in writing. A clear contract, with payment terms, security deposit, maintenance responsibilities and grounds for termination, drastically reduces future disputes.

1. Draft or adapt a complete lease agreement, ideally reviewed by a professional.
2. Clearly define the amount of the security deposit and the conditions for its return.
3. Set a monthly payment deadline and specific consequences for late payment.
4. Document the condition of the property at handover, with photographs and an inventory signed by both parties.
5. Keep a copy of all the documentation from the screening process.

Frequently asked questions

What share of income should rent represent?

As a general guideline, rent should not exceed roughly one third of the tenant's monthly net income, although this figure can vary depending on the city, the candidate's profile and local market conditions.

Is it mandatory to require a guarantor (aval) to rent?

It isn't always mandatory, but it is a common and advisable practice, especially when the tenant's income is variable or hard to document. The guarantor acts as additional backing in case of default.

How can I verify whether a candidate is telling the truth about their income?

Request several months of proof of income, compare the information with their ID and contact details, and, if possible, confirm directly with the employer or through bank references.

What should I do if the ideal candidate has no references from previous landlords?

If it's their first time renting, you can compensate with solid employment references, a guarantor with verifiable property or a larger security deposit, always within what local regulations allow.
