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 pro-forma recomputes as soon as you finish a cell (press Enter or click away). Raise Year-1 Other Income, and NOI, cash flow, and the metrics bar at the top of the Financial section update before you've even pressed Save.
The preview is not committed — pending edits show their effect on the model, but the saved value is unchanged until you click Save. This is the difference between "what if" and "I've decided".
What's in the preview
- Every calculated row, all 10 years — EGI, NOI, Net Cash Flow, debt service, DSCR, cash flow before and after taxes, cumulative cash flow, property value, gross rent multiplier, equity multiple, and cash-on-cash return.
- The metrics bar — Year-1 NOI, cap rate, gross potential income, total operating expenses, DSCR, pre-tax cash flow, cash-on-cash, and property value.
- The NOI chart below the metrics.
Work mode
Work Mode expands the pro-forma table to the full width of your screen and hides the metrics bar, the Cap Rate & Financing panel, and the chart. Toggle it with Work Mode in the Financial toolbar; press Esc or click Exit Work Mode to go back.
Use it when you want to see all ten years of the model at once. Exit Work Mode to check the metrics again.
Side-by-side scenarios
Today, the live preview shows the impact of pending edits vs the current saved state. Want to see what changed between saves? Open the Financial section's History (version history) to see each change and revert it.
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, use Export Excel to keep a copy, and model the alternative case in Excel. Pushing a case back with the Excel add-in replaces the version in Relm.
Performance
The recompute happens in your browser for every edit, including financing changes — there's no server round-trip, so the preview stays responsive. Changes in the Financing panel also save automatically (you'll see Saving… then Saved), unlike table edits, which wait for Save.
