A centralized lease database for commercial real estate gives landlords and asset managers one reliable place to store, track, and manage every lease detail: documents, key dates, tenant contacts, compliance items, and critical notes without digging through email threads or scattered spreadsheets. By keeping everything organized and searchable in a single system, you can reduce missed deadlines, improve team coordination, and respond faster to tenant needs while maintaining cleaner records across your entire portfolio.
How to Input a Lease Extension/Amendment Into STRATAFOLIO
You have a lease extension executed, how do you input that extension/amendment into STRATAFOLIO?
Keeping track of expiration dates and lease escalations in STRATAFOLIO is imperative to keeping an updated portfolio. The lease already entered has the security deposit, the lease options to renew, and copies of the original lease. There is no need to start over and re-enter all of that. Here are the steps to Extending a lease.
- If the Lease Expiration has passed or the type of lease has changed, Change the Lease Status
- Extend the Lease Expiration Date
- Add Lease Rate Escalations
- Extend or Add the Operational Expense period if needed
- Add Contract to Files
Instead of inputting a new lease, we want to extend the current lease for historical purposes. The only reason why we would suggest expiring the old lease and adding a new lease is if lease terms drastically changed or for a tenant acquiring someone else’s lease.
Changing the Lease Status
When the expiration date passes, STRATAFOLIO automatically marks a lease as Expired. Locate the lease under Left Hand Navigation > Operations > Leases > i

NOTE: The Leases table will display all leases, current, future, and expired, inputted into STRATAFOLIO. Expired leases will not show under the Building or Unit views if a newer lease has been entered. They will also not show on the Rent Roll if they have expired.
After you have chosen the proper lease, under the Lease Abstract select the Edit Lease button.

Modify the Lease Status drop-down to the appropriate status.

Change Expiration Date
Modify the Lease End Date to the new end date on the amendment or extension.

If the tenant has executed an option, update the Lease Renewal options with (option # executed) so it is clear how many options remain. Then choose Save.

Add Lease Rate Escalations
Now that the lease end date is extended, the Lease Rates can be modified. The Lease Term or End Date must be extended to be able to enter the new escalations. You cannot add Lease Rates past the end of the Lease Term.
Navigate to the Lease Rates Tab, then select Add a Lease Rate.

STRATAFOLIO will automatically calculate the dates for the next year and populate them. Modify dates as needed.
Enter the new Lease rate amount, type, and whether the lease rate is confirmed or not. In the lease rate notes, STRATAFOLIO’s Onboarding team enters the document where the lease rate is located. Please use the note field for whatever notes you need for this specific lease rate period. The Late Fees and Due Date should pull through from previous rates. The Income Item should also pull through – but be sure it is the correct Income Item you would like to utilize for invoicing. Select Save or select the Add Another function to continue adding escalations.

NOTE: These dates must be within the dates entered for the Lease Term. The Lease Rate end date can not go past the lease’s end date or before the lease’s start date.
Extend Operational Expenses if Needed:
Navigate to the Op-Exp tab and the pencil button next to the appropriate year – extend the period expiration if needed. You can only extend this period until the end of the Lease Term.


Note: STRATAFOLIO Onboarding recommends utilizing a new Operating Expense period each year. At the end of this year, you can utilize our cloning feature to copy over the same sub-categories you have used. Find directions for that feature at How to Clone Operating Expenses or CAM in STRATAFOLIO. After cloning, you can update the invoice amounts for the next year as needed.
Add Contract to Files:
Select the Files tab. Select the Upload button.

Upload up to 10 files at a time by dragging and dropping or selecting the button to browse and find the file.

Choose the file type and write a description if needed. You can choose whether the tenant can access this file if you have an active tenant portal. For more information, check out this Knowledge Base article about Lease File Upload Options.
Now that you have updated the lease with the new expiration date, new escalations, new operating expenses, and new files, it’s important to use the current lease to maintain complete historical data on each tenant. This will save you from having to re-enter data that has already been entered. To ensure that the escalations are correct, run the Rent Roll.
Unconfirmed Lease Rate Alerts and What It Means
An alert in your email means something in STRATAFOLIO needs your attention. If this is your first time getting a Lease Rate Unconfirmed Alert, it may be confusing as to why it was sent. There are several reasons, as we will explain in detail.
Understanding alerts
When entering Lease Rates, you may have noticed a small checkbox after the amount column. If you did not check it when entering the Lease Rate, that may be the reason why. If you leave this unchecked, you will get these alerts 30 days before the lease will escalate.

One reason for this box not being checked by the Onboarding team is normally for the leases that escalate by an unknown rate, i.e., by the Consumer Price Index or CPI. When entering these lease rates, the future can be unknown, but STRATAFOLIO still needs to alert you that an escalation may occur. It is important to show on the Rent Roll that the lease will escalate even if the amount is unknown until it happens. When this box is unchecked, STRATAFOLIO will send an alert that there is an Unconfirmed Lease Rate.

In the emailed alert, select the View link, which will bring you directly to the Lease in question. Look in the Lease Rates tab for the escalating Lease Rate. Select the pencil icon to edit the Rate.

If the Base Rent amount needs to be modified due to a different CPI rate, change it. Then choose the Lease Amount Confirmed Box and Save.

There are other reasons that the Onboarding team will leave the Confirmed Lease Rate box unchecked. Including unclear rates in the lease, such as an “Annual increase of no less than 2%.” The team will enter a 2% escalation, but the amount may be different when the time comes. The alert is to help you verify that you are charging the correct amount and that you are letting the tenant know what the new amount will be 30 days prior.
Lease File Upload Options
Keeping track of important paperwork such as leases, loans, certificates of insurance, and countless other files requires a savvy filing system for the commercial real estate property manager.

By default, all files are initially set to Hide access and cannot be viewed by the Tenant in the Tenant Portal. You can update each file with View, Edit, or Delete access if you choose. If you do not change the file access, it will remain hidden from the tenant’s view. Access levels and how to download & view files are discussed below.

Tenant access permissions can be edited by clicking the Edit pencil button next to the file you would like. Once you click the Edit button, the Edit File Information popup will appear and you can select Tenant Permissions from a dropdown list.

File Access Permissions
There are four file permission levels for files in STRATAFOLIO. Detailed information for each level is below. For more information on file uploads and what the tenant view is like in the Tenant Portal, click here.

How to Handle Sub-Leases and Lease Assignments
When a tenant assigns or transfers a lease to another entity, such as in the case of an assumption or sub-lease, STRATAFOLIO provides two options to correctly manage the change.
You can either modify the existing lease to reflect the new tenant or close out the old lease and create a new one, depending on the lease terms.
Option 1: Handle the Sub-Lease by Modifying the Existing Lease
If the lease terms remain unchanged and the new tenant is simply assuming the existing lease, follow these steps:
- Add the New Tenant and Contact
- Navigate to Contacts and add a new Contact for the incoming tenant.
- Navigate to Tenants and add a new Tenant record.
- Edit the Existing Lease
- Search for the lease in STRATAFOLIO and select Edit Lease.
- Replace the old tenant with the new tenant.
- Under Invoicing, update the Accounting Customer to the new customer record synced from QuickBooks.
- Document the Change
- In the Lease Closing Notes, explain the situation briefly (e.g., “Lease assumed by Burlington Coat Factory after Jo-Ann Fabric bankruptcy”).
- Upload the assignment or sub-lease documentation to the Files tab of the lease record.
This approach ensures that the lease continues seamlessly under the new tenant while maintaining the financial and historical integrity of the record.
Option 2: Handle the Sub-Lease by Closing and Creating a New Lease
If the terms of the lease are changing, or if your accounting process requires a clean start:
- Close the existing lease by marking it as Expired.
- Create a new lease for the new tenant.
Use the article: How to Add a Lease and Assign a Unit.
This method provides a clear delineation between the two tenant agreements for reporting and audit purposes.
Best Practice
- Always include supporting documentation (e.g., bankruptcy filings, assumption agreements) in the Files tab.
- Double-check the QuickBooks Accounting Customer link to ensure proper synchronization.
- Note any relevant financial or legal transitions in the Lease Notes to maintain a complete audit trail.
