AI Task: Reconcile Estoppel to Lease

The estoppels are coming back. You have 14 tenants, a closing date in three weeks, and each certificate needs to be compared line by line against the executed lease and every amendment on file. Rent amounts, escalation dates, renewal options, security deposits, expense structures: if the tenant confirmed something different from what the lease says, you need to know before the buyer’s attorney does.

The work is not complicated. It’s just slow. Reading a 40-page lease, cross-referencing it against the estoppel, calculating the dollar impact of each variance, and writing up a specific next step for every finding takes 30 minutes per tenant on a focused day. When you have a full rent roll to reconcile and three other diligence workstreams running in parallel, the estoppel review is the first thing that gets compressed.

That’s exactly what this task is built to fix.

What This Task Does

You upload three things: the tenant’s signed estoppel certificate, the executed base lease, and any amendments or addenda. Then you pick your output format (in-chat or Word document). That’s the entire setup.

From there, the DD and Closing Specialist (with Memory) reads every document, layers the addenda chronologically so the most recent terms control, and compares every line the tenant confirmed against what the lease actually says. Each term gets categorized: Match, Discrepancy, Estoppel Silent, or Not in Lease. For discrepancies, the AI calculates the annualized dollar exposure and writes a specific action directive. Not “review this further.” Instead: “Send revised estoppel to tenant reflecting the $4,200/mo rent per Section 3.2 of the First Amendment.” For estoppel-silent items, it flags the material lease terms the tenant did not address and explains why each one matters.

The whole process takes roughly 5 minutes of your time. The AI does the rest.

Who This Task Is For

Estoppel review is a non-negotiable part of acquisition diligence. Every certificate that comes back needs to be compared against the lease, and every variance needs to be documented before closing. The gap is never awareness of the risk. It’s having the bandwidth to give each estoppel the attention it deserves when you’re processing an entire rent roll under deadline.

This task is built for:

• Acquisitions teams who are mid-diligence on a multi-tenant deal and need every estoppel reconciled before the buyer’s attorney starts asking questions
• Due diligence analysts who need a consistent, repeatable reconciliation format across 10, 20, or 50 tenants
• Asset managers who received a tenant estoppel and want to verify the tenant’s claims against the lease file before responding
• Attorneys and paralegals who are preparing estoppel summaries for buyers, lenders, or title companies and need the discrepancies documented with dollar exposure

In short: if you already have the estoppel and the lease, this task gives you the reconciliation.

Why It Matters

A single missed discrepancy between what the tenant confirmed and what the lease says can become a post-closing liability. An estoppel that claims a lower rent, an unexercised option the tenant says was exercised, a side agreement that never made it into the lease file: these are the findings that change deal economics after the wire has already gone out.

You already know this. Anyone who has closed an acquisition knows that estoppels are where surprises hide.

The problem is not awareness. It’s that a proper reconciliation, reading the full lease, layering in every amendment, cross-referencing each term against the estoppel, calculating the exposure, and writing an actionable next step, takes 30 minutes per tenant. When you have 15 tenants and a closing in three weeks, the math doesn’t work. Something gets skimmed. Something gets missed.

Without this task, the reconciliation either takes all day or gets reduced to a quick scan. Discrepancies surface late, after the PSA is signed, after the lender has issued the commitment letter. That’s when they get expensive.

This task takes that 30-minute process and compresses it to 5 minutes. Same rigor. Same coverage. Specific dollar exposure and action directives for every finding. That’s the multiplier.

What the Output Looks Like

The reconciliation report generated by this task includes:

• A one-line verdict (Clean, Minor Issues, or Action Required) with total annualized dollar exposure
• A discrepancy list sorted by dollar impact, each with what the estoppel says, what the lease says, and a specific action directive
• Estoppel-silent flags identifying material lease terms the tenant did not address, with an explanation of why each one matters
• Not-in-lease alerts for any tenant claims or side agreements not found in the executed documents
• A compact lease summary with key economics, dates, options, expense structure, and guarantor details

The output is not a checklist with green checkmarks. It’s a reconciliation report with dollar exposure and directives, the kind of work product you’d expect from a diligence analyst who read every page of every document.
