What it does

What Sauna does for lease analysts

01
Abstract the lease
Sauna reads a signed lease and pulls the key terms — base rent, escalations, options, and CAM treatment — into a structured Airtable record with the source clause cited.
02
Track critical dates
It maintains a Google Sheet of renewal, option, and notice deadlines across the portfolio, and drafts a Slack alert before each one so no window is missed.
03
Recalculate rent and CAM
Sauna recomputes scheduled rent steps and CAM reconciliations from the abstracted terms, flags any tenant billing that doesn't match the lease, and shows its math.
04
Draft the portfolio summary
It builds the portfolio roll-up — occupancy, weighted average lease term, and upcoming expirations — citing each lease so the asset team can trust the read.

Good to know

Questions, answered.

Can I trust the abstracted terms?

Each term in the record links to the exact lease clause it came from, so you can verify the abstraction against the document before relying on it.

Will it adjust tenant billing on its own?

No. Sauna flags where billing doesn't match the lease and shows the recalculated figure. Any change to a tenant's charges happens only after you approve it.
