A portfolio of leases, read one at a time
A lender wants twelve estoppels by the end of the month, a tenant just returned your lease with a new co-tenancy clause, and the property manager's contract renews in six weeks. The lease file for each building sits in a different folder.
Without goHeather
- Lease amendments drafted by editing the last one by hand
- Estoppels checked line by line against a stack of amendments
- Outside counsel billed to read a standard vendor contract
- Tenant markups traded by email with no clear record of what moved
- Renewal options and notice dates tracked in a spreadsheet someone forgets to update
With goHeather
- A first draft from your own lease or amendment form in minutes
- Each estoppel compared with the lease and every amendment
- Tenant markups read against the positions you set
- Counter-redlines sent from Word with track changes, then signed electronically
- Counsel focused on the acquisitions and anchor leases that need them
Draft a lease amendment from your own form
Start from your standard lease, amendment, work letter or property management agreement, or pick a lawyer-made template. Answer a few questions about the tenant, the premises and the economics, and goHeather returns a full first draft. Need a clause your form does not have? Ask for it and it goes into the draft.
Lease review for tenant markups, before the next call
Upload the tenant's redlined lease, a buyer's draft purchase agreement or a vendor's service contract for one of your buildings. goHeather reads the whole document, ranks what it finds and quotes each clause, so asset management knows what changed before anyone gets on the phone.
A leasing playbook for every building you own
Tenants and their brokers push on the same clauses deal after deal. Set your positions once (the expense cap you will give, the transfers you will allow, the renewal window you need) and goHeather checks each lease and amendment against them.
Ask a question across the whole lease file
When a broker or lender calls with a question about a tenant, type it the way you would ask a colleague. goHeather answers from the lease and its amendments and points to the clause behind the answer.
From commercial leases to vendor contracts
The agreements a real estate owner or operator drafts, negotiates and signs across a portfolio.
- Leasing
Leases, amendments and estoppels
Draft a lease or amendment from your own form, or review the tenant's markup. When an estoppel comes in, goHeather compares it with the lease and every amendment, so a rent figure or option date that does not match is caught before it reaches the lender.
- Transactions
Purchase and sale agreements
Review the buyer's or seller's draft for deposits, due diligence periods, closing conditions and representations. See our purchase and sale agreement review page.
- Operations
Property management agreements
Fees, leasing commissions, spending authority, reporting and termination, read against the terms you want from a manager.
- Buildings
Work letters and service contracts
Tenant improvement work letters, plus the janitorial, HVAC, elevator and security contracts that keep each property running.
From first draft to signed lease
No setup project and no data migration. Start a draft or upload a lease file, and your first result usually comes back while the tenant is still waiting on your reply.

Start from your form or their markup
Draft a lease, amendment or work letter from your own form, or upload the tenant's redline, an estoppel or a vendor contract as PDF or Word.

What goHeather drafts and checks in a commercial lease
A single tenancy can span a base lease, three amendments, a work letter and a guaranty, and the rent in the original lease may no longer be the rent the tenant pays. goHeather covers the clauses below when it drafts from your own lease forms. When it reviews a tenant's markup, an estoppel or a buyer's draft, it reads the related documents together and quotes each clause with a plain-English summary of how it is written. What to do about any of them is a decision for you and your lawyer.
Rent, operating expenses and CAM
- Base rent and escalations. The starting rent per square foot, how it steps up, and whether the schedule in the lease matches the one in the latest amendment.
- Operating expense pass-throughs. What is included, what is excluded, and whether controllable expenses are capped.
- CAM reconciliation. When the annual statement is delivered, how long the tenant has to dispute it, and whether the tenant has audit rights.
- Free rent and abatement. How many months, when they apply, and whether they are recaptured if the tenant defaults.
Term, renewal, transfers and co-tenancy
- The renewal option. How many options, the window for exercising them, and how the renewal rent is set.
- Assignment and subletting. Which transfers need consent, which are permitted, and whether the landlord keeps a recapture right.
- Co-tenancy and exclusives. What triggers a rent reduction, how long it lasts, and how the exclusive use is described.
- Early termination and holdover. Any termination option, the fee attached to it, and the rent that applies if the tenant stays past expiration.
Estoppels, amendments and purchase agreements
- The estoppel certificate. Each figure and date the tenant certifies, compared with the lease and its amendments, with every mismatch quoted.
- Lease amendments. What each amendment changes, and which earlier terms still apply after it.
- Deposits and due diligence. In a purchase and sale agreement, the earnest money, when it goes hard, and how the due diligence period is written.
- Representations and closing conditions. What the seller represents about the rent roll and leases, and what has to happen before closing.
Management, work letters and service contracts
- Property management fees and authority. The management fee, leasing commissions, and the spending limit above which the manager needs owner approval.
- Tenant improvement work letters. The allowance, who manages construction, how cost overruns are split, and how delays affect the commencement date. For the contractor side of the build-out, see our construction page.
- Facilities and maintenance contracts. Scope, response times, insurance requirements and how the owner can end the contract when a building is sold.
- Vendor agreements. Auto-renewal terms, price increases and indemnities in the contracts each building signs with its vendors.
How goHeather fits your contract process
Real estate teams sign hundreds of leases, amendments and vendor contracts across a portfolio, and the details that matter most (a renewal date, an expense cap, a transfer right) are easy to miss when each file is read by hand. With goHeather, drafts start from your own forms, tenant markups and estoppels get a first read with the clauses above quoted and summarized, counter-redlines go back in Word with track changes, and the final version is signed and stored in one place. Asset managers get answers faster, finance teams can check the numbers against the lease, and in-house counsel spend their time on the acquisitions and anchor leases that need them.
goHeather is a contracts AI, not a law firm. It tells you what your lease or agreement says and what to look at. It does not tell you what to accept.
