🔍 Phase 1

Market Research

⏱ Timeline: 4–8 weeks before LOI

✅ Key Tasks

  • 1Identify 5–10 target properties matching your size, location, and use requirements
  • 2Obtain comparable lease transactions (comps) for your submarket and building class
  • 3Research current asking vs. effective rent spreads in your target area
  • 4Evaluate vacancy rates — high vacancy gives you negotiating leverage
  • 5Identify the landlord's situation: motivated to lease, or holding out for top dollar?
  • 6Get a tenant rep broker engaged before you tour any properties

⚠️ Common Mistakes

  • Starting your search without a broker — you pay nothing for a tenant rep, but they know market intel you don't
  • Touring properties before you know your space requirements (SF, layout, term)
  • Accepting quoted rents at face value without knowing the effective rent after concessions
  • Ignoring building class and landlord financial stability during initial screening
🤖 How LeaseAI Helps

LeaseAI can analyze sample leases from comparable properties to show you what terms other tenants in your submarket are getting — giving you a baseline before you walk into any negotiation.

📝 Phase 2

Letter of Intent (LOI)

⏱ Timeline: 2–3 weeks

✅ Key Tasks

  • 1Draft LOI covering all material business terms: SF, rent, term, TI allowance, free rent, options
  • 2Specify rent commencement vs. lease commencement separately
  • 3Include tenant improvement allowance amount AND delivery timeline expectations
  • 4Define your renewal options and expansion rights in the LOI — harder to add later
  • 5Negotiate exclusivity period (30–45 days) so landlord stops shopping the space
  • 6Keep LOI non-binding on legal terms but specific enough to prevent scope creep in lease drafting

⚠️ Common Mistakes

  • Being vague in the LOI — ambiguity in the LOI becomes ammunition for the landlord in lease drafting
  • Skipping the LOI and going straight to lease — you lose negotiating leverage on business terms
  • Not including a TI allowance in the LOI (it's much harder to add after the LOI is signed)
  • Signing an LOI that isn't truly non-binding — some LOIs create obligations you didn't intend
🤖 How LeaseAI Helps

LeaseAI can review your LOI against market standards to flag missing provisions and identify terms that favor the landlord before you commit to lease drafting.

3
🔬 Phase 3

Due Diligence

⏱ Timeline: 2–4 weeks concurrent with LOI

✅ Key Tasks

  • 1Obtain 3 years of actual CAM/operating expense history from the landlord
  • 2Review zoning confirmation for your intended use
  • 3Inspect the premises for deferred maintenance, HVAC condition, electrical capacity
  • 4Verify building HVAC capacity for your occupancy density and equipment needs
  • 5Research landlord financial stability — is there a mortgage, is it in good standing?
  • 6Confirm parking ratio, hours, and any shared/reserved parking arrangements
  • 7Request a copy of any existing REA (Reciprocal Easement Agreement) or CCR

⚠️ Common Mistakes

  • Skipping the CAM expense history review — 3 years of actual data reveals true occupancy costs
  • Not confirming zoning/use before signing anything — some uses require special permits
  • Failing to inspect HVAC condition — replacement can cost $100K+ and responsibility depends on the lease
  • Ignoring landlord financial health — a distressed landlord is a risk factor for your entire tenancy
🤖 How LeaseAI Helps

Upload any draft operating expense statements or CAM reconciliations to LeaseAI for automatic extraction of exclusions, caps, and audit rights so you know exactly what your exposure is.

4
📄 Phase 4

First Draft Review

⏱ Timeline: 1–2 weeks

✅ Key Tasks

  • 1Have your attorney review the full lease draft (never skip this step)
  • 2Upload to LeaseAI for instant extraction of all key data points and risk flags
  • 3Verify that all LOI terms are accurately reflected in the draft
  • 4Review the operating expenses definition — identify what's included and excluded from CAM
  • 5Confirm the TI allowance disbursement conditions and timeline
  • 6Mark every provision where the landlord's standard form favors the landlord over market norms
  • 7Create a redline issues list with every modification you intend to request

⚠️ Common Mistakes

  • Relying on the landlord's attorney to flag issues — their job is to protect the landlord
  • Signing a lease without reading it because "it's the landlord's standard form"
  • Missing TI allowance recapture provisions that require repayment if you leave early
  • Overlooking hazardous materials representations and environmental indemnification language
🤖 How LeaseAI Helps

LeaseAI extracts all 16+ key data points from your lease draft in under 60 seconds — base rent, escalations, TI allowance, CAM caps, renewal options, SNDA requirements, and more. Use the sample report at /sample-report to see exactly what you get.

🤝 Phase 5

Negotiation

⏱ Timeline: 2–6 weeks (varies widely)

✅ Key Tasks

  • 1Submit your full redline in one package — not piecemeal over multiple rounds
  • 2Prioritize your asks: identify "must have," "strongly prefer," and "nice to have" positions
  • 3Negotiate CAM caps (3–5% annual cap on controllable expenses is market standard)
  • 4Push for an SNDA from any existing and future lender as a lease condition
  • 5Negotiate termination rights: early termination option with defined fee at year 5 for a 10-year lease
  • 6Lock in renewal option rents: fair market value with a cap, or fixed step-ups
  • 7Confirm TI allowance disbursement triggers and what happens if landlord misses timeline

⚠️ Common Mistakes

  • Negotiating in phone calls without written confirmation — everything must be in writing
  • Accepting "we never do that" without pushing back — almost everything is negotiable in CRE
  • Conceding too many points early — hold your important positions for the final round
  • Not getting a personal guarantee limitation — try to limit personal guarantee to a burn-off after 3 years
🤖 How LeaseAI Helps

Compare your negotiated terms against market benchmarks using LeaseAI to confirm whether the concessions you've won are in line with what other tenants are getting in your submarket.

✅ Phase 6

Final Terms

⏱ Timeline: 1–2 weeks

✅ Key Tasks

  • 1Confirm all negotiated changes are reflected in a clean final draft
  • 2Re-read the entire lease — not just the redlined sections
  • 3Verify rent schedule, commencement date, and expiration date math is correct
  • 4Confirm SNDA, estoppel, and subordination provisions are consistent and acceptable
  • 5Review exhibits: work letter, floor plan, rules and regulations, any permitted use addenda
  • 6Confirm attorney's approval of final form before proceeding to signature
  • 7Calculate total lease cost including all escalations and CAM exposure over full term

⚠️ Common Mistakes

  • Assuming the final draft matches your agreed changes without re-reading — errors happen
  • Missing changes buried in exhibits or attachments
  • Not calculating the 10-year total cost including escalations — this is the real number
  • Forgetting to confirm the personal guarantee is limited to the agreed scope
🤖 How LeaseAI Helps

Run the final executed lease through LeaseAI to create your permanent lease abstract — a clean summary of every key term you'll need to reference for the next 5–10 years.

7
✍️ Phase 7

Signing

⏱ Timeline: 1 day to 2 weeks

✅ Key Tasks

  • 1Ensure all signatories have proper authority (officers with corporate authorization, LLC manager authorization)
  • 2Collect landlord's executed copy — you want a fully signed lease, not just your signature
  • 3Deliver security deposit and first month's rent as required by the lease
  • 4Confirm the lease commencement date trigger if it's condition-based (e.g., substantial completion)
  • 5Submit any required certificates of insurance to landlord before taking possession
  • 6Request confirmation of SNDA execution from any existing lender
  • 7Get a copy of the recorded SNDA if required

⚠️ Common Mistakes

  • Not confirming signatories have authority — a lease signed by an unauthorized individual may be unenforceable
  • Delivering security deposit without confirming where it's held (segregated trust account vs. operating account)
  • Taking possession before the fully executed lease is in your hands
  • Not reading the insurance requirements before signing — some requirements need weeks to implement
🤖 How LeaseAI Helps

After signing, upload the fully executed lease to LeaseAI to create your permanent lease abstract and calendar all key dates: rent commencement, renewal option deadlines, CAM audit windows, and lease expiration.

8
🏢 Phase 8

Post-Signing

⏱ Timeline: Ongoing through lease term

✅ Key Tasks

  • 1Calendar all critical dates: renewal notice deadlines (typically 6–12 months before expiration), CAM audit windows, expansion option exercise windows
  • 2Review CAM reconciliation statements annually — errors and inflated charges are common
  • 3Exercise your audit rights if CAM charges look inconsistent with the lease
  • 4Monitor landlord compliance with maintenance and repair obligations
  • 5Track any assignment or change of ownership in the building (triggers SNDA and estoppel obligations)
  • 6Begin renewal negotiations 18–24 months before lease expiration for best leverage
  • 7If you want to assign or sublet, read your assignment clause carefully before committing to anything

⚠️ Common Mistakes

  • Missing renewal option notice deadlines — most options are "time is of the essence" and missed deadlines forfeit the right
  • Never auditing CAM reconciliations — overpayments are common and cumulative
  • Waiting until 6 months before expiration to think about renewal — landlord's leverage is maximum then
  • Modifying the premises without written landlord consent, which can trigger restoration obligations at move-out
🤖 How LeaseAI Helps

LeaseAI's lease abstract keeps all critical dates in one place. Set alerts for renewal deadlines, CAM audit windows, and expansion option exercise periods so nothing falls through the cracks.
