About ES Quantum
A property management company that works in two counties and nowhere else.
What we do
ES Quantum Property Management looks after commercial, multifamily, and residential property in Miami-Dade and Broward. We lease it, collect the rent, keep it maintained, enforce the lease, and report to the owner every month. The company has been doing this since 2016.
We chose to stay in South Florida because property management is a local business. The rent a three-bedroom gets in Miramar, how long a Brickell condo board takes to approve a tenant, which roofer shows up after a storm: none of that transfers from one market to the next.
Who runs it

Eleonora Sebos has worked in real estate for more than 30 years, on both the commercial and the residential side, in North and South America. She has represented buyers, sellers, landlords, tenants, and investors, and has handled the acquisitions, the leasing, and the asset management herself.
She founded ES Quantum PM in 2016. It started small, as a support service for her own investor clients: people who had bought property in Florida and needed someone to look after it. The work grew from there into a full property management company.
Her view is that management doesn’t stop at collecting rent and fixing things. The job is to protect what the owner paid for and get the property earning what it should. She is also a real estate specialist in the commercial and residential division at Complete Realty Group, so a client can buy, lease, manage, and eventually sell through one relationship.
How we work
Put it in writing
Screening criteria, notices, repair approvals, inspection reports. If it matters, there’s a document and a date.
Show the numbers
Owners see every dollar in and out, with the invoice behind each expense.
Say the uncomfortable thing early
If the rent you want is above the market, or the unit needs work before it will lease, you hear it in the first conversation.
Treat tenants fairly
Same standards for everyone, repairs done promptly, deposits returned on time. Tenants who are treated well stay longer.
Who we work with
- Owners with one or two rental homes or condos
- Investors with a portfolio across both counties
- Out-of-state and international owners who can’t be here in person
- Owners of small retail, office, and flex buildings
Where we work
All of Miami-Dade County and all of Broward County, from Homestead to Deerfield Beach.
