The Lease Tracker That Flags Renewals Before You Have To Remember

Lead: Every lease tracker template promises visibility into your portfolio. Almost none of them promise to remember a renewal date for you. We analyzed the official lease and property templates from monday.com, Airtable, and Notion, kept the one genuinely useful idea each one contributes, fixed what all three get wrong, and rebuilt the result as a free, open source Baserow template you can download and own outright.

Why lease trackers fail at the one job that matters

A lease tracker exists to answer one question: what's about to expire, and does anyone know about it? Every landlord, property manager, and facilities lead who has ever managed more than a handful of leases has watched a renewal deadline slip past because it lived in a spreadsheet nobody opened that week, or a calendar reminder tied to a person who changed jobs.

The failure isn't a missing field. Every lease tracker on the market has a "renewal date" column. The failure is that the renewal date sits there as inert data — a fact recorded, not a fact surfaced. Nothing about the record changes when the date gets close. Nothing turns red. Nothing shows up on a list unless someone remembers to sort by it, and by the time someone remembers, the tenant has already started shopping for their next space or the commercial lease has auto-renewed into terms nobody re-negotiated.

A lease tracker earns its place when it tells you what's expiring without you asking it to. That's the standard we used when we rebuilt this category, and it's the test worth applying to any lease template you're evaluating — including this one.

What the competitive set actually gives you

We ran the official (or closest-to-official) lease and property templates from monday.com, Airtable, and Notion through our extraction pipeline — same rubric, same eight-avatar review panel, all three scored on demand, reusability, and enterprise readiness. Each one contributes exactly one idea worth keeping. None of them ships the one thing a lease tracker should actually do.

monday.com: the right framing, no visible mechanism

monday.com's lease agreement template positions itself correctly: "a flexible workspace for managing property-related workflows, from lease documents and renewal dates to maintenance tasks, budgets, and approvals." That's the right scope — a workflow tool, not a document generator — and it's why this single post currently ranks for every keyword in our target cluster, roughly 6,220 searches a month across residential and commercial variants.

What it's missing: proof. The page describes "dashboard visibility" for renewal dates, but nothing in the public material shows an actual computed flag, a formula, or an exception view. It reads as a landing page selling the monday.com platform, with the lease template as a supporting example rather than a fully specified deliverable. You can't inspect what "visibility" means until you've already signed up.

Airtable: the right data model

Airtable's Lease Tracker gets the entity model right where most templates get it wrong. It's built for "the busy landlord" tracking apartment units, buildings, and tenants as related concerns — not one flat spreadsheet of leases with property and tenant crammed into text columns. It also encourages attaching lease documents, tenant notes, and unit photos directly to records, which builds a genuinely useful per-unit dossier.

What it's missing: any renewal logic at all. The gallery page shows no formula field, no exception view, no notification concept. The three-way structure (units, buildings, tenants) is real and worth borrowing — but a lease tracker with no renewal mechanism is a filing cabinet, not a tracker.

Notion: the right renewal UX, the wrong foundation

Notion's Tenant, Lease & Property Tracker sells exactly the experience a lease tracker should have: "built-in reminders, calendar views, and quick-access dashboards" for "lease renewals, rent payments, and occupancy." A calendar view of upcoming renewals is the closest any competitor gets to the thing we actually want.

What it's missing is durability. "Built-in reminders" in Notion means a reminder tied to your personal account inside a live Notion workspace. It doesn't survive an export. It doesn't work if you hand the tracker to a new property manager, migrate it to another tool, or open a duplicated copy without reconfiguring the automation from scratch. It's a feature that only works as long as nothing about your setup ever changes — which, for a growing property portfolio, is not a safe assumption.

The three, side by side

Each competitor wins exactly one column. Ours is the only one with a check in every row.

The rebuild: all three ideas, one open source template, plus the piece nobody ships

Our Property Lease & Renewal Tracker combines Airtable's relational three-entity model, Notion's renewal-forward visibility, and monday.com's correct workflow framing — built on Baserow, the open source Airtable alternative you can self-host. Then we added the feature none of them actually demonstrate: a renewal flag that computes itself, ships with the schema, and keeps working after you export, import, or hand the base to someone else.

The Starter edition ships with:

Three linked tables. Properties, Tenants, and Leases — each a real entity, not a text column pretending to be one. A lease links to its property and its tenant. Properties aren't duplicated across lease rows; they're records with their own address, type, owner, and unit count.

An Expiring_Soon flag nobody has to configure. A formula field checks whether a lease's Renewal_Date falls within the next 60 days and whether the lease is still Active or Pending. If both are true, the flag fires. It does not fire on leases that have already been Renewed or Terminated, even if their old renewal date happens to sit inside that 60-day window — a subtlety every competitor's marketing copy glosses over and that we tested for explicitly.

An Expiring Soon view that leads the template. Open the base, click once, see every lease approaching its renewal window across every property you manage. This is the view that replaces "let me go check the spreadsheet."

Working sample data with deliberate exceptions. Eight leases across eight properties — four correctly flagged as expiring soon, and four deliberately not flagged, including one lease renewed just ten days before its old date and one lease terminated with its renewal date only twenty-six days out. Both prove the flag doesn't fire on stale dates from closed records, which is exactly the mistake a naive "is the date close" formula makes.

What "open source" buys you here

The fair pushback: Buildium, AppFolio, and TenantCloud already do lease tracking. Why does open source matter for this category specifically?

No per-unit pricing. This is the sharpest wedge in this category. Property management platforms routinely charge per unit, per door, or per property under management — a cost that scales linearly with the exact thing you're trying to grow. A landlord with 40 units and a landlord with 4 pay wildly different bills for the same feature set. Self-hosted Baserow has no per-unit fee at any portfolio size.

Your tenant data stays yours. Lease records carry real personal information — tenant names, contact details, financial terms, sometimes background-check references. Self-hosting means that data lives inside infrastructure you control, not a third party's cloud with its own breach history and its own terms of service that can change.

The renewal formula is inspectable. Open the field definition and you can read exactly what "expiring soon" means — a date comparison and a status check, not a black-box "smart" feature behind a paid tier. If you want to change the window from 60 days to 90, you edit one formula. Nobody has to file a support ticket.

How the lifecycle works

The underlying workflow is the same one we found scattered across all three commercial sources:

Property Onboarded → Tenant Assigned → Lease Signed → Active → Renewal Window → Renew or Vacate → Audit

The Starter edition implements the spine that matters most: a linked three-table model, a Renewal_Date on every lease, and a formula-driven Expiring_Soon flag that surfaces what needs attention without anyone building a report. The Operational edition (coming next) adds a configurable notice-period window, a renewal-status workflow (Notice Sent / Renewing / Vacating), a missing-insurance-document flag, and a rent-roll dashboard. The Enterprise edition adds role-based owner dashboards, an audit trail of lease amendments, and an approval checkpoint for renewal-term changes above a rent threshold.

That staging is deliberate. A three-table base you understand in five minutes gets adopted by the landlord managing a dozen units. A governance layer with approval checkpoints on day one gets abandoned by exactly that same landlord.

Evaluation checklist for any lease tracker template

Building your own instead, or evaluating a different tool? Hold any candidate against these five questions:

1. Are properties, tenants, and leases separate linked records, or is everything crammed into one flat sheet?
2. Does anything flag an approaching renewal automatically, or does someone have to remember to check a date column?
3. If a lease is already renewed or terminated, does the renewal flag correctly stay silent — or does a stale date create a false alarm?
4. Does the renewal reminder survive an export, an import, or a change of ownership — or does it live inside one person's account?
5. Does the pricing model punish you for managing more units, or does it stay flat as your portfolio grows?

The commercial templates in this category each pass one or two. The point of an open source rebuild is to pass all five — and to let you verify that claim by reading the formula yourself.
