With 33 years in the market, Unioncorp specializes in insurance and lease guarantees for the real estate sector. The company was founded around the time Brazil’s Tenancy Law was enacted, when surety insurance began gaining traction. Since then, Unioncorp has partnered with insurers and property managers to structure this type of guarantee, which today stands as the company’s core focus.
“Our flagship product is surety insurance, and we’re fully focused on the commercial real estate market,” says Cristina Caldeira, CEO of Unioncorp. She notes that although the product is widely known, there is still a lack of understanding about its use in commercial and structured deals, especially long-term ones.
“It’s possible to take out coverage for the entire lease term and spread the premium over monthly payments, which helps avoid draining a company’s cash flow,” explains Caldeira.
Unioncorp offers two alternatives: the Capitalization Bond and Surety Insurance. The first acts like an invested security deposit — a financial reserve agreed upon by landlord and tenant that can be applied to residential or commercial properties with less red tape.
Surety insurance, on the other hand, removes the need for a guarantor or upfront deposit and is considered the most comprehensive guarantee in the market. It covers overdue rent and charges such as property taxes and utility bills, and can even cover potential damage to the property.
Surety insurance is a type of lease guarantee that replaces the need for a guarantor or traditional security deposit. In this model, an insurance company takes on the responsibility of covering any amounts owed by the tenant in case of default — including rent, common area fees, and property tax (IPTU).
The policy is quick to issue, subject to a credit check, and can be paid in up to 60 installments. It ensures income for landlords — even offering advanced payments during eviction proceedings — and includes legal support, as well as customizable coverage depending on the type of property, whether it’s a shopping mall, industrial properties, or built-to-suit facility.
Caldeira notes that the corporate sector still has doubts about surety insurance. She sees growth potential through greater awareness and education.
“We need to educate the market. Many companies tried surety insurance in the past and didn’t like it. But the product has evolved and can now be a powerful ally.”
According to her, Unioncorp’s role is to simplify the process through straightforward communication, quick analysis, and tailored solutions. Its expertise in commercial real estate — from office spaces to warehouses — allowed the company to develop its own risk analysis tools, a crucial step in getting policies approved.
“The tenant is the risk, and the insurer needs to understand who that tenant is. It’s not just about having money — you need to have credit,” Cristina emphasizes.
In many cases, when a company is newly established or lacks a track record, Unioncorp looks for alternatives such as evaluating the individual behind the business as a counter-guarantor or using capitalization bonds.
For real estate agencies, surety insurance means reduced operational costs and more legal certainty. For tenants, the biggest benefit is avoiding impacts on credit lines or balance sheets — which makes surety insurance an appealing option even compared to traditional guarantees.
Unioncorp also acts as a partner in more complex operations, including built-to-suit agreements and long-term leases ranging from 10 to 30 years. According to Caldeira, the insurance market is not always equipped to handle such deals, creating space for companies with technical expertise and specialized focus.
“Insuring large, established companies is easy. But that’s not Brazil’s reality. The reality is dealing with smaller structures and finding viable solutions for them.”
Cristina believes surety insurance is becoming an increasingly strategic tool in uncertain times, as past crises have shown.
“Some companies stopped generating revenue but kept paying rent — because there was a guarantee in place. In Brazil, anything can happen. Surety insurance protects both tenant and landlord.”
