Cary Rosenblum's career can be read as a long argument with the handoff. A banker hands capital to a buyer. A developer hands drawings to a contractor. A contractor hands keys to a manager. The manager inherits every clever decision and every expensive mistake. Most firms accept those borders as the natural geography of real estate. Rosenblum kept crossing them.
The result is Elmington, the Nashville company he co-founded with Ben Brewer in 2010. Its parts now cover affordable housing, construction, residential investment and development, commercial property, owner-focused management and property technology. Each arm has its own work, but the larger idea is a loop: the people who finance and design a building can learn from the people who build and operate it.
Rosenblum arrived at that model through finance. At the University of Georgia's Terry College of Business, he studied real estate finance and entrepreneurship, graduating cum laude from his MBA program in 2003 as a Frances Wood Wilson Foundation Scholarship recipient. At Regions Bank, where he became a vice president in the commercial real estate group, he financed more than $500 million in transactions through debt and equity executions. The job taught the grammar of deals - risk, return, collateral, timing and the delicate choreography of other people's money.
A company discovers its shape
Elmington began in the aftermath of the financial crisis, when damaged loans and bank-owned properties had made real estate unusually available and unusually complicated. The early work was investment work. Yet buildings have a rude habit of becoming physical. They need walls fixed, leases signed, residents served and budgets revisited after the assumptions meet weather, labor and time.
In 2011, the new company broke ground on Crescent Bluff in Memphis, its first affordable housing project. The development had 72 homes. Its ambitions were larger than its count. Rosenblum described the mission as using federal, local and private support to create housing with the quality associated with Class A communities at a price working families could afford. The sentence contains the whole puzzle: several kinds of capital, one built result, and rents constrained by purpose.
“Our mission for the development was to utilize federal, local and private financial support to create a quality of housing typical of Class A apartment communities at a price point that is affordable for working families.”Cary Rosenblum on Crescent Bluff
The company kept adding capabilities. It formed a property-management business in 2012, the same year it bought the 596-unit Fountain Square portfolio in Louisville for $22 million. An affordable division followed in 2013. Construction and residential divisions arrived in 2017. Fortress, a property-management software operation born from the frustrations and patterns of apartment operations, launched as a division in 2019; Rosenblum serves as chairman of the company now known as Fortress OS.
This sequence is more useful than a polished founding myth. It shows a company learning its shape in public. One line of work revealed the next recurring dependency. The business did not merely collect adjacent services; it brought more of the consequences of an investment decision under the same roof.
The charm and burden of owning the loop
Vertical integration sounds magnificent in a strategy meeting. In practice, it means that fewer mishaps can be dismissed as somebody else's department. A construction delay will reach an operating budget. A management complaint can expose a design flaw. A weak underwriting assumption will still be there when the resident opens the utility bill. Information travels faster, but so does accountability.
Rosenblum's stated remit reflects that width. He oversees corporate operations and the company's primary business divisions while working on operating and financial goals, strategic growth, acquisitions, new business and relationships with financing partners. Those duties put him at the junction where a building is simultaneously an investment, a construction project, a workplace and somebody's address.
He appears to build executives as well as divisions. Kerri Davis, who rose from a small Elmington team to lead Fortress, has recalled that Rosenblum saw leadership potential in her before she did. She said he kept pushing her toward new roles. It is a revealing management anecdote because integrated companies cannot run on a founder's attention alone. They require people willing to own the seams.
A timeline measured in capabilities
The numbers became substantial. In 2024, Elmington celebrated more than 10,000 affordable units and began another 1,850 across Tennessee, Florida, North Carolina, Texas, Ohio and North Dakota. In the National Multifamily Housing Council's 2025 ranking, its management operation appeared at No. 42 with 38,953 apartments under management. Rosenblum had earlier been named the Nashville Business Journal's 2020 CRE Investor of the Year.
Awards and rankings are tidy. Housing is not. The affordable side depends on tax credits, bonds, public agencies, private lenders and rules tied to household income. It rewards people who can keep a complicated capital stack upright without allowing complexity to become an excuse for a forgettable building. Rosenblum's Crescent Bluff quote is striking because it rejects the visual shorthand that low rent must mean low ambition.
Elmington's growth is not simply a story of doing more things. Its divisions sit along one chain of consequences, from underwriting to the resident experience.
The 99-year horizon
Eastpoint Flats, now rising on Nashville's East Bank, brings that chain into one project. Elmington and The Fallon Company broke ground in May 2026 on 323 income-restricted homes. Plans include an 8,420-square-foot childcare facility and 12,600 square feet of retail. The Tennessee Housing Development Agency committed more than $120 million through tax-exempt bond authority and housing tax credits expected to generate equity. An $80 million construction financing package followed.
The most interesting number is neither 323 nor $80 million. It is 99 - the length in years of the ground lease designed to preserve affordability. That term carries the project beyond the careers of everyone who negotiated it. A conventional deal asks whether the building can open and perform. A century-long promise asks whether the structure can resist future land pressure while continuing to function as a piece of the city.
Rosenblum did not supply the project's public quotation; Elmington affordable-housing partner Hunter Nelson did. That, too, fits the mature version of the company. The founder's influence is visible less in a microphone than in the institutional machinery assembled behind the moment: development expertise, construction capacity, financing relationships and an operating organization that will inherit the keys.
The practical lesson is to own a handoff only when learning from it will improve the whole system.Not every adjacency is an advantage
What builders can steal
The first lesson from Rosenblum's career is to follow the recurring problem, not the fashionable market. Property management was useful because Elmington owned and developed apartments. Construction was useful because the company needed tighter control over schedules, costs and execution. Software was useful because managers encountered repeatable operational friction. Each move could feed information backward into the one before it.
The second lesson is that financial literacy becomes more powerful, not less, as an operator moves toward the customer. A capital stack is not paperwork sitting above the building. It shapes the rent, design, timeline and range of possible promises. Rosenblum's bank experience gave him fluency in the constraints. Elmington's expansion forced those constraints into conversation with residents and operations.
The third is that scale changes the founder's job. When a company spans many states and several business lines, clever deals stop being sufficient. The work becomes goals, systems, partner relationships and leaders who can make decisions without waiting outside the chief executive's office. Rosenblum's public profile is unusually quiet for a founder of a business this broad. The operating chart is louder.
There is no need to romanticize integration. It can create bureaucracy as readily as insight. The discipline is to know why each capability belongs. If the answer is merely revenue, the structure may wobble. If the answer is a faster, more honest feedback loop, the complexity has a chance of paying rent.
Sixteen years after Elmington's founding, Rosenblum is still working inside the same essential puzzle he met in finance: how to align capital, property and time. The difference is proximity. The spreadsheet now has a construction team, a manager, a software screen, a childcare center and a 99-year clock attached to it. The deal became a system because he kept following where it went.
