Built for
For acquisition teams reviewing rent rolls with inconsistent columns, mixed date and currency formats, concessions, vacant units, loss-to-lease questions, and incomplete lease records.
AI rent roll analyzer
Turn a multifamily rent roll into underwriting inputs you can audit
Rook reads unit-level schedules, normalizes the fields that matter, and keeps the original evidence close enough for an analyst to verify the exceptions.
The outcome
Move from a broker or seller spreadsheet to a structured unit picture and a populated model without losing the rows that require human judgment.
How it works
From source package to reviewable work
- 01
Bring the rent roll as received
Upload the source file with the rest of the deal package. Rook works from the schedule your team received instead of requiring a clean export first.
- 02
Normalize unit and lease fields
Rook organizes each unit label, layout, occupancy state, term dates, in-place charge, asking amount, and concession into one review surface.
- 03
Surface exceptions before aggregation
Blank dates, duplicate units, ambiguous statuses, unusual values, and other issues stay visible rather than disappearing into a portfolio average.
- 04
Map the result into your workbook
Reviewed facts flow into the rent-roll assumptions and summaries your model expects, while the source remains available for checking.
What the team gets
Fast enough to use. Clear enough to review.
Unit-level structure
Create a consistent view of unit types, beds and baths, square footage, status, rents, and lease timing from an inconsistent source schedule.
Occupancy and exposure context
Separate occupied, vacant, notice, and unclear records so occupancy conclusions are tied to the status logic used.
Rent comparison inputs
Organize contract and market rent fields for loss-to-lease and mark-to-market analysis while retaining the underlying values.
Exception-led review
Focus analyst attention on anomalous or incomplete rows instead of asking someone to re-check every clean row with equal effort.
Why the details matter
A rent roll is evidence, not just a table
A useful rent roll analysis starts below the summary. Unit status conventions vary by operator, dates may represent different lease events, and a single blended average can hide the rows that drive near-term exposure.
Rook preserves the unit-level record while creating the aggregates a model needs. Reviewers can inspect how a summary was built and return to the supplied schedule when a status or rent value is unclear.
The analysis becomes part of the complete underwrite rather than an isolated converter: rent roll outputs can be reconciled with the OM, operating statement, firm assumptions, and the model cells they inform.
Frequently asked questions
Questions acquisition teams ask
What does a rent roll analyzer do?
A rent roll analyzer organizes unit and lease records, calculates reviewable property-level summaries, and highlights incomplete or unusual rows. Rook also connects those outputs to the firm's existing underwriting model and source documents.
Can Rook analyze an Excel rent roll?
Yes. Rook is designed to work with rent roll files included in a multifamily deal package, including spreadsheets with firm- or operator-specific columns. Ambiguous fields may still require analyst confirmation.
Does it calculate occupancy and loss to lease?
Rook can organize the unit status, contract rent, and market rent inputs used for those analyses. The exact calculations and definitions can follow the firm's own underwriting model and status conventions.
Can I trace a summary back to individual units?
Rook is built around source traceability and review. Unit-level records and exceptions remain available so a reviewer can understand what produced a property-level conclusion.
