About Lennar Mortgage, LLC
Lennar Mortgage, LLC is a full-service residential mortgage lender and financial services subsidiary of Lennar Corporation (NYSE: LEN), one of the largest homebuilders in the United States. It provides conventional, FHA-insured, and VA-guaranteed home loans, primarily to buyers of Lennar-built homes, and is headquartered in Miami, Florida. Because of its role as a mortgage lender, the company collects a wide range of sensitive personal and financial information from loan applicants and borrowers.
What Happened?
Lennar Mortgage, LLC was listed in a Texas Attorney General data security breach report (record BR-0005257). According to that filing, an unauthorized party gained access to company systems during a window spanning May 26th, 2026 through June 1st, 2026, with the breach discovered on June 1st, 2026. The incident affected 348,416 individuals in total. The compromised information included names, addresses, Social Security numbers, driver’s license numbers, other government-issued ID numbers such as passports and state ID cards, financial account information, medical information, and dates of birth. Lennar Mortgage notified affected consumers by U.S. Mail, by publication in print media, and through its website. The company is offering 24 months of complimentary identity monitoring through Kroll, with notifications to affected individuals beginning on August 11th, 2026.
It is worth noting that other law firm investigations and reports to other state attorneys general describe a broader Lennar Corporation incident involving unauthorized access through sophisticated social engineering tactics between March 24th and March 30th, 2026, with a forensic assessment concluding on July 30th, 2026. The Texas Attorney General filing covers Lennar Mortgage specifically with a different breach window of May 26th through June 1st, 2026. Because the breach dates do not overlap and the reporting entities differ, it is unclear whether these represent two separate incidents or subsidiary-specific reporting of a single broader event. Multiple law firms, including Migliaccio & Rathod LLP and Federman & Sherwood, opened investigations in August 2026, though no class action complaints specific to this breach have been confirmed as filed. The parent company, Lennar Corporation, also experienced a prior data breach in July 2023 that exposed the names and Social Security numbers of approximately 7,448 individuals.

What Should You Do?
If you received a notice from Lennar Mortgage, LLC, enroll in the 24-month identity monitoring service through Kroll as soon as possible and note any enrollment deadline included in your notice. Whether or not you enroll in that program, consider placing a fraud alert or credit freeze with all three major credit bureaus — Equifax, Experian, and TransUnion — to help prevent new accounts from being opened in your name. Review your credit reports for any unfamiliar accounts or inquiries by visiting AnnualCreditReport.com, where you can access free reports from each bureau. Monitor your bank and financial accounts closely for unauthorized transactions. Because medical information was also reported as compromised, review any Explanation of Benefits statements from your health insurer and check your medical records for services you did not receive. If you discover signs of fraud or identity theft, report them at IdentityTheft.gov, which provides a personalized recovery plan.
