Summarize this content:
A property management company's data should belong to the company, not to whichever platform happens to be storing it. John Michael Elliott, who runs S&D Real Estate Services, switched to Rentvine specifically because his previous software made that impossible. Using Rentvine's open API, his team now builds custom reports, connects outside tools, and moves data wherever the business needs it to go.
What does it mean for a property management platform to hold your data hostage?
Data lock-in means a company's own records, owner and tenant history, financials, custom fields, are difficult or impossible to extract and use outside the platform that stores them. It's rarely an explicit policy. It shows up as a closed data model, a gated API, or an export format nobody can actually work with. Rentvine's API is open and bidirectional from day one, so a property management company can read and write its own data freely instead of asking permission.
"Our data was kind of being held hostage for us," Elliott said of his previous software. "We wanted to make sure that we had the ability to use our data the way we wanted to use it."
Why did S&D Real Estate need more than a closed system?
S&D Real Estate Services was founded in 2006, when a downturn in the housing market left people unable to sell homes and needing a property manager instead. As the company grew, Elliott's team ran into a ceiling common to closed platforms: the software could store their data, but it wouldn't let them do much with it.
The deciding factor in moving to Rentvine wasn't a single feature. It was the platform's approach to integration. "How it played well in the sandbox with other softwares, I think was a big choice we had that really led us to that," Elliott said.
What does Rentvine's open API actually let a growing company do?
An open API means outside tools can read and write a company's data directly, rather than pulling a one-way export. For S&D, that translates into custom reporting built around fields specific to their business. "The ability to create reports in our system with user-defined fields, be able to search by those user-defined fields," Elliott said, describing what changed after the switch.
That same access lets the team pull data out of Rentvine and into other systems they rely on. "The ability to take our data, manipulate it, get data from the data that we provided to other systems that we use," he said, pointing to this as one of the clearest gains from the move.

Why does data freedom matter more as a company scales?
The more a property management company grows, the more it depends on connecting specialized tools, AI-driven leasing, accounting add-ons, reporting dashboards, to its core platform. A closed API turns every one of those connections into a negotiation with the software vendor. Elliott described the shift in blunt terms: "We saw the benefit of moving towards a more freeing company, I could say. The freedom we received in Rentvine was unmatched by any other competitor that was out there."
John Michael's take
Asked whether switching to Rentvine was worth it, Elliott didn't leave room for doubt. "I would say 100% it is definitely worth it," he said. "It's a game changer. A million percent. Not even 100%, a million percent."
Frequently asked questions
What is vendor lock-in in property management software?
Vendor lock-in happens when a property management company's own data, owner and tenant records, financial history, custom fields, is difficult to extract or use outside the platform storing it. It's usually caused by a closed or gated API rather than an explicit policy. Rentvine avoids this by offering a bidirectional API included in the base platform, so companies can access and use their own data at any time.
Why do property managers want an open API?
An open API lets a property management company connect its own data to other tools, custom reports, accounting systems, AI leasing platforms, without waiting on the software vendor to build that connection. Rentvine's API is open and bidirectional from day one, which is why customers like S&D Real Estate Services use it to build custom reporting around fields specific to their own business.
What's the difference between a one-way and a bidirectional API?
A one-way API only lets data flow out, typically as a static export. A bidirectional API lets outside tools both read and write data, which is what makes real integrations, not just exports, possible. Rentvine's API is bidirectional and included at no additional cost, rather than reserved for a premium tier.
Can property management software connect with the other tools a company already uses?
Yes, if the platform's API is genuinely open. Rentvine's open API is built to play well with outside systems, which is the specific reason S&D Real Estate Services cited for choosing Rentvine over other platforms they evaluated.
How do user-defined fields help with property management reporting?
User-defined fields let a company track and report on details specific to its own business, information a standard report template wouldn't capture. Rentvine allows companies to create reports around these custom fields and search by them directly, which is what let S&D Real Estate build reporting suited to how they actually operate.
The bottom line
A property management company's data should move as freely as the business needs it to, not stay locked behind whatever platform happens to be storing it. John Michael Elliott's team at S&D Real Estate Services builds custom reports, connects outside tools, and works with their own data on their own terms using Rentvine's open API. As he put it: "The freedom we received in Rentvine was unmatched by any other competitor that was out there."
