why some people in Florida do not sign the lease with people from Mexico without any US paper work

 In Florida, landlords who refuse to sign leases with individuals from Mexico (or any other country) who lack U.S. paperwork are typically motivated by financial risk management, legal anxieties, and standard property management screening policies.

While federal law does not explicitly prohibit landlords from renting to undocumented immigrants, landlords face practical obstacles when an applicant has no U.S. identification or history. [1, 2]

1. Inability to Run Standard Background & Credit Checks

The primary reason is risk assessment. Standard property management workflows rely heavily on U.S. systems to verify an applicant's reliability:

• No Social Security Number (SSN): Without an SSN or an Individual Taxpayer Identification Number (ITIN), a landlord cannot run a standard credit check to see an applicant's payment history. [1]
• Lack of U.S. Rental & Employment History: Landlords look for verifiable U.S. income (like W-2s or pay stubs) and references from previous landlords to ensure the tenant can and will pay rent. [1]

2. Fear of Financial Loss and Eviction Complications

If a tenant stops paying rent, damages the property, or vanishes, a landlord relies on the legal system to recoup financial losses.

• Without valid U.S. paperwork, it is incredibly difficult for a landlord to track a person down, serve them legal papers, or send unpaid debt to a collection agency. [1]
• If a tenant is suddenly detained or deported, the landlord faces an immediate loss of rental income, an abandoned property filled with belongings, and a complicated legal process to reclaim and re-rent the unit. [1]

3. Florida’s Strict Political and Legal Climate

Florida has enacted some of the strictest immigration laws in the country (such as SB 1718). While that specific state law focuses heavily on employment, healthcare, and human smuggling rather than residential renting, its highly publicized passage created a climate of fear and confusion. Many landlords mistakenly believe they face severe state penalties or criminal charges for entering into any contract with an undocumented individual. [1, 2, 3]

4. Legal Protections vs. "Uniform Standards"

Under the federal Fair Housing Act (FHA), it is completely illegal for a landlord to discriminate against someone based on their national origin or race. Because citizenship and national origin are closely linked, completely banning non-citizens can expose a landlord to a federal lawsuit. [1, 2]

To protect themselves from discrimination lawsuits, landlords use a defense called "uniform screening criteria." As long as a landlord requires the exact same paperwork (e.g., a valid U.S. state ID, a credit score over 650, and verifiable U.S. income) from every single applicant regardless of where they are from, courts generally rule that they are not discriminating. Because an undocumented applicant cannot produce these standard items, they are filtered out by the policy, not explicitly by their nationality. [1]

Alternative Options for Applicants

For individuals in this situation, standard corporate apartment complexes will almost always reject the application. However, options still exist:

• Private Landlords: Independent, "mom-and-pop" landlords are often more flexible and may accept a foreign passport, proof of cash reserves, a larger security deposit, or a co-signer.
• Obtaining an ITIN: An applicant can apply for an Individual Taxpayer Identification Number (ITIN) from the IRS, which allows them to build a credit history and apply with landlords who accept it in place of an SSN. [1, 2]
