Form an opinion,
not a spreadsheet
Basecase turns raw Rent Rolls and T12s into a fully populated institutional model in minutes — so your hours go to judgment, not data entry.
Your first 2 deals are free. No demo call, no annual contract.
A full IC-grade model — GP/LP waterfall, sensitivities, debt sizing — delivered as real Excel with live formulas. Audit any cell. Maintained by us.
TLS in transit, AES-256 at rest. Row-level security on every table holding customer data.
Deal files are never used to train models. Delete a deal, it's gone — files and derivatives.
No implementation project. No training sessions. Open Basecase, drop your files, get a model back in minutes.
Every deal starts the same way: hours of cleanup before anyone can form an opinion.
You open a Rent Roll, a trailing twelve, maybe a market survey. None of them match. None of them reconcile. By the time the model is actually populated, the afternoon is gone — and the real work, the judgment work, hasn’t started.
Basecase does the cleanup. You do the thinking.
Where the
afternoon goes
Data prep that used to eat an afternoon drops to a cup of coffee — and the hours come back as judgment, not overtime.
| Task | By hand | With Basecase |
|---|---|---|
| Re-key the rent roll, unit by unit | 60–90 min | parsed for you |
| Tie out the T12 until it reconciles | 45–60 min | reconciled for you |
| Populate the model — with MTM and sign conventions handled | 60–90 min | populated for you |
| Build and maintain the template itself | a standing project | ships with Basecase |
| The mechanical 80% | ≈ 4 hours | minutes |
| Form an opinion — the work that moves the deal | whatever’s left | the whole afternoon |
A typical first pass on a mid-size multifamily deal · your first 2 deals are free — time it yourself
Pressure-test the deal,
side by side
Every assumption editable per scenario, every return recomputed in seconds. Scenarios are a sandbox — nothing touches your saved deal until you promote one.
Upload. Review. Decide.
Basecase handles the first 80% of every underwrite — the mechanical part — so your hours go to judgment, not cleanup.
Drop your files
A Rent Roll and a T12, in whatever shape they arrived. PDF, Excel, scan — parsed and reconciled in minutes.
Handles Yardi, RealPage, Entrata, AppFolio, OneSite, MRI, ResMan, Buildium — and the hand-built ones.
Review your assumptions
Every input on one screen — rent growth, vacancy, exit cap, debt terms. Defaults where you want them, overrides where you don’t.
Untouched defaults stay visibly muted — reviewers see exactly what the analyst changed.
Get your model
A populated .xlsm with live formulas — waterfall, debt sizing, and the sensitivity grid your IC will ask for first.
Base case highlighted · every formula live — audit any cell.
The model for you.
The memo for your IC.
Every run ends in two artifacts. The .xlsm you work in — and a one-page memo for the room: returns from deal gross to LP net, sources and uses, the sensitivity grid, the hold-period cash flows, and any assumption that trips a risk rule, flagged with the rule that fired.
Source files and run date are stamped at the foot of the page. The numbers carry their receipts.

“I underwrite multifamily deals for a living, and I run every one of them through Basecase — it’s the tool I built because I was tired of losing afternoons to reformatting rent rolls. The work that actually moves a deal — pressure-testing assumptions, knowing a submarket, arguing about exit caps — is work software can’t do. Everything before it is work software should do. So I built that, and I use it every day.”
