Cosign, a Livingston-based guarantor platform built for the apartment industry, has launched nationwide.
The company uses data-driven underwriting to help more renters qualify for leases while giving property owners stronger protection against missed payments and vacancy losses.
In a year-long beta across more than 150,000 units, Cosign reported a 90% renter approval rate and no partner churn among participating management companies.
The platform is designed to help owners fill units faster, stabilize revenue, and boost occupancy across all asset types, from affordable housing to new Class A developments.
Cosign points to a persistent industry challenge: more than 40% of renters are denied their first-choice apartment because they cannot meet qualification requirements. By combining real estate expertise with modern data science, the company aims to update how renter risk is evaluated.
With only about 2 million of the nation’s 55 million rental units currently using any form of guarantor alternative—less than 5% of the market—Cosign’s leadership sees significant room for growth and an opportunity to educate owners and operators on how modern underwriting can expand access while improving financial performance.
The value and demand for suburban garden-style apartment communities in New Jersey continue to be strong, as shown by this recent 13-property portfolio deal.
