When you're testing assumptions, you want to see the impact on returns immediately — before deciding whether to commit. Relm has two complementary tools for this: Live preview and Work mode.
Live preview
While you're in Edit Mode, the return summary at the top of the Financial section recomputes as you type. Change Year 1 rent growth from 3% to 4%, and the IRR ticks up before you've even pressed Save.
The preview is not committed — pending edits show their effect on the model, but the database value is unchanged until you click Save. This is the difference between "what if" and "I've decided".
What's in the preview
- NCF per year — refreshed across all 10 years.
- IRR — recomputed.
- Equity multiple — recomputed.
- DSCR per year — refreshed.
- Stabilized NOI — usually Year 2 or 3.
Work mode
Work mode pins the return summary to a fixed position so it stays visible as you scroll through the model. Toggle it from the Financial section header.
This is the right mode when you're doing 10+ edits in a session. Without work mode, scrolling the model out of view of the summary means you don't see the cumulative impact until you scroll back.
Side-by-side scenarios
Today, the live preview shows the impact of pending edits vs the current saved state. Want to compare two saved scenarios? Use version history to diff a previous saved version against the current one.
True parallel scenarios (e.g. "base case" and "downside case" living side-by-side at the same time) are on the roadmap. The interim workflow is: save your base case, branch to a Excel export, edit there, then sync back via the Excel add-in — you can keep both versions accessible.
Performance
The recompute is local in the browser for almost all edits — typing into Year 4 R&M doesn't make a server round-trip. So even very fast typing keeps the preview responsive. The exception is debt term changes, which can trigger a small server-side recomputation; you'll see a brief "Recomputing…" indicator.
