DSCR (Debt Service Coverage Ratio) loans qualify borrowers based on rental property income rather than personal employment income, serving real estate investors. This is a non-agency product sold to private investors rather than government entities like Fannie Mae or Freddie Mac.
Rocket Pro partners had been requesting DSCR loans for years. Our competitors already offered these products, putting Rocket at a competitive disadvantage in serving the growing investor market. Industry data showed DSCR loans representing nearly 30% of non-QM loan activity, with demand up more than 50% year-over-year.
Following Rocket's acquisition of Redfin, we needed the ability to close loans under rebuttable presumption guidelines, creating an opportunity to expand our product offerings while serving a new segment of clients who may not qualify under conventional guidelines.
What initially seemed like a "handful of screens" expanded into updates across nearly every part of the Rocket Pro portal:
We launched two DSCR products simultaneously - a 30-year fixed and a 40-year interest-only option - each with different qualification requirements and restrictions.
I was the sole designer supporting this feature across 200+ people from engineering, product, capital markets, and compliance teams.
Requirements changed weekly throughout the 6-month project. Our product manager had to fight for Rocket Pro representation in planning meetings, as the Product Lab team initially focused on the retail channel despite brokers being the primary users.
I received Slack messages with new field requirements regularly - sometimes conflicting with previous specifications. With over 110 stories and 50+ acceptance criteria in Azure DevOps, maintaining clear documentation became critical to project success.
Updates spanned both SPARK and RDS6 design systems, with our newer R4 system on the horizon. Many pages hadn't been updated in years and required complete rebuilds to match current design patterns before I could even begin implementing DSCR-specific changes.
The pricing calculator, for example, needed to be reconstructed from scratch - essentially doing double the design work to baseline the experience and then layer in new functionality.
Since DSCR is a non-agency product, investor requirements could change at any time. We designed for flexibility, minimizing hard-coded logic that might need updates if regulations changed. This meant documenting every conditional state and variation for engineering teams to implement.
With requirements changing frequently and tight compliance constraints, my focus was operational excellence: maintain crystal clear documentation, annotate every state and logic variation, and ensure engineering teams had exactly what they needed to build correctly the first time.

Updates spanned both SPARK and RDS6 design systems (For instance the Applying section is in SPARK and the Structuring section is in RDS6). I had to baseline existing experiences before implementing new requirements, essentially doing double the work for pages that needed design system migration.
The launch of Rocket Pro's DSCR product generated significant industry attention, with coverage across major mortgage publications:
"Our partners have been asking for DSCR at Rocket Pro. When we developed the product, it made sense — what they wanted was not just the product, but they wanted it coupled with what Rocket Pro is known for when it comes to pricing, consistency, speed, and then, of course, certainty."
— Cory Scholl, Executive Vice President of Sales, Rocket Pro
Multiple industry publications covered the launch, noting Rocket's entry into the DSCR space as a significant market development. The product arrived as DSCR loans were experiencing explosive growth industry-wide, with demand up more than 50% year-over-year.
6-month project (May-November 2024) with one deadline extension due to evolving compliance requirements. Coordinated across multiple engineering teams, product managers, and compliance stakeholders throughout.
Launched mid-November 2024 with minimal post-launch issues. No design fixes required since launch - engineering teams had clear specifications that translated cleanly to production.
One account executive sent a Slack message expressing excitement about the launch, noting how long partners had been requesting this capability.
Last year, Rocket Pro processed $100B in total loan volume across all products. Adding DSCR unlocks a new market segment - real estate investors who qualify based on rental income rather than employment income - allowing our partners to serve clients they previously couldn't help.
