The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Conditional Possession Information Requirement

This validation ensures that either the 'Possession Date' is filled out or the 'Possession Remarks' field contains text. The form indicates with a '♦' symbol that one of these two fields is mandatory. This is crucial for providing clear possession terms to potential buyers. If neither field is completed, the form submission will fail, prompting the user to provide the necessary information.

Contract Expiry Date Logical Consistency

This check verifies that the 'Expiry Date' is on or after the 'Contract Commencement Date'. A contract cannot expire before it begins. This logical validation prevents data entry errors that would create an invalid contract term. If the expiry date precedes the commencement date, an error message will be displayed, requiring the user to correct the dates before proceeding.

Canadian Postal Code Format Validation

This validation ensures the 'POSTAL CODE' field adheres to the standard Canadian A#A #A# format (e.g., M5V 2T6). Correctly formatted postal codes are essential for mail delivery, geolocation services, and data integrity within the system. A submission with an incorrectly formatted postal code will be rejected, and the user will be instructed to enter a valid postal code.

Mandatory Fields for 'Sale of Business' Type

This check enforces that if the property 'TYPE' is selected as 'Sale of Business', then all fields marked with '♦' on page 8 (e.g., 'Financial Statement', 'Chattels', 'Employees', 'Seats') must be completed. This information is fundamental to evaluating a business for sale. Failure to provide this mandatory data will block the form submission until all required fields for a 'Sale of Business' listing are filled.

Conditional 'Use' for 'Institutional' Category

This validation enforces the rule that if the 'CATEGORY' is selected as 'Institutional', the 'USE' must be one of the options marked with '*T1' (Bank, Church, School, Other). This ensures that the property's use is correctly classified within its institutional category. Selecting a non-T1 use for an institutional category will result in a validation error, forcing the user to select a valid combination.

Shipping Door Dimensions Dependency

This check ensures that if a number greater than zero is entered for any of the shipping door count fields (e.g., 'TRUCK LEVEL SHIPPING DOORS #'), the corresponding dimension fields (Height and Width) become mandatory. It is illogical to have doors without dimensions. If the door count is positive but dimensions are missing, the submission will be flagged with an error, requiring the user to provide the measurements.

Common Mistakes in Completing Form 590

The ones the AI is built to catch.

Ignoring Conditional Mandatory Fields
This form uses symbols (e.g., ◘5, ♦) to indicate that a field is mandatory only if a specific property type is selected. Users often overlook these instructions and fail to provide required information, such as shipping door dimensions for an 'Industrial' property. This results in an incomplete listing that may be rejected by the MLS system, delaying market exposure. To avoid this, carefully cross-reference all selections with the conditional rules; if the form is a non-fillable PDF, AI-powered tools like Instafill.ai can convert it to a fillable version and automatically enforce these dependencies to ensure completeness.
Mismatched Numeric Values and Unit Codes
This mistake occurs when a user enters a numeric value in a field like 'Total Area' but selects the wrong corresponding unit from the 'Total Area Code' checklist (e.g., entering '2' and checking 'Square Feet' instead of 'Acres'). This leads to a gross misrepresentation of the property size, which can mislead buyers and create legal liabilities. Always double-check that the number entered aligns logically with the unit of measure selected. Using a tool like Instafill.ai can help by validating related fields against each other to catch such inconsistencies.
Leaving Required '0' Value Fields Blank
The form explicitly instructs users to enter '0' for certain fields if they are not applicable, marked with a '▲' symbol (e.g., 'Lot Front' for a condo). Many people miss this instruction and leave the field blank, which can cause data processing errors or be interpreted as missing information. This can delay the listing process until the form is corrected. To prevent this, carefully read all field-specific instructions and enter '0' where required.
Inaccurate or Incomplete Legal Description
The 'Legal Description' field requires the official property description, which is often long and complex. Users may try to abbreviate it, use the common street address, or copy it incorrectly from an unreliable source. An incorrect legal description can cause significant problems during title search and closing, potentially derailing the transaction. This information should be copied precisely from official documents like the deed or a recent survey.
Ambiguous Possession Information
The form states that 'ONE OF POSSESSION DATE OR POSSESSION REMARKS IS MANDATORY'. A common error is to either leave both blank or fill in both, creating ambiguity about the seller's intentions for possession. This can lead to confusion and disputes during offer negotiations. To avoid this, decide on one clear path: either provide a specific date or use the remarks field for flexible terms, but not both.
Missing Seller Initials on Pages
This multi-page document requires the seller's initials at the bottom of each page to acknowledge the information presented. It is very common for one or more pages to be missed, especially in a long form like this. A missing initial can invalidate the information on that page or cause the entire listing agreement to be rejected by the brokerage, requiring the agent to go back to the client for correction and causing delays.
Typos in Critical Identifier Fields
Fields like 'PIN #' and 'Assessment Roll # (ARN)' are unique identifiers used to link the listing to the correct property in various databases. A simple typo, such as transposing two numbers, can cause the listing to be associated with the wrong property or be rejected by the system entirely. These numbers must be transcribed with extreme care from official sources. AI form-filling tools like Instafill.ai can help by cross-validating these numbers against public records to ensure accuracy.
Incorrect Property Classification
The 'Details' section has a complex, hierarchical classification system (Type -> Category -> Use) with specific dependencies. Users often select combinations that are not valid, such as selecting 'Farm' as the Type and 'Warehouse' as the Use. This creates a logically inconsistent and inaccurate listing, which can be misleading and cause the property to be marketed to the wrong audience. It is crucial to follow the logic of the form carefully.
Incomplete 'Sale of Business' Financials
When the 'Sale of Business' type is selected, a large number of fields in the 'Financial Information' section become mandatory, as indicated by the '♦' symbol. Agents sometimes overlook this and fail to enter crucial data like 'Gross Income/Sales' or 'Operating Expense'. This omission makes it impossible for potential buyers to evaluate the business's viability, rendering the listing ineffective. Smart form tools can automatically flag these required fields based on the 'Sale of Business' selection.
Providing Invalid or Improperly Branded URLs
The form includes fields for various URLs, such as virtual tours, with specific fields for 'Unbranded' versions. A frequent error is pasting incorrect or broken links, which frustrates potential buyers. Another common issue is placing branded content in the 'Unbranded Virtual Tour URL' field, which violates MLS rules and can lead to the listing being flagged or removed. All URLs should be tested before submission, and branding rules must be strictly followed.

What is the purpose of Form 590?
Form 590, the Commercial Sale MLS® Data Information Form, is used by real estate professionals to gather detailed information about a commercial property to create a comprehensive listing on the Multiple Listing Service (MLS®).
Who is responsible for filling out this form?
The listing brokerage or salesperson completes the form based on information provided by the property seller. The seller must then review the information, initial each page, and sign the final page to confirm its accuracy.
What documents should I have on hand to complete this form accurately?
To fill out this form, it is helpful to have your property tax bill for the Assessment Roll Number (ARN), a property survey for lot dimensions, and financial statements if you are selling an associated business.
What do the symbols like *, ▲, and ♦ mean next to certain fields?
These symbols indicate mandatory fields required for the MLS® listing. For example, '▲' means you must enter '0' if the field is not applicable, while '♦' indicates that at least one of a pair of fields is mandatory.
The 'Details' section is complex. What is the difference between 'Type', 'Category', and 'Use'?
These fields classify the property from general to specific. 'Type' is the main classification (e.g., Industrial, Farm), 'Category' is a sub-classification (e.g., Industrial Condo), and 'Use' defines the specific business activity (e.g., Warehouse, Restaurant).
What information goes in the 'Financial Information' section on page 8?
This section is mandatory only when the 'Type' is 'Sale of Business'. It captures key financial data like gross income, operating expenses, and net income to provide to qualified buyers.
Why do I need to initial every page of this 9-page form?
Initialing each page serves as the seller's acknowledgment that they have reviewed and verified the accuracy of the information on that page. This ensures the integrity of the data being entered into the public MLS® listing.
What is the difference between 'Inclusions' and 'Exclusions'?
The 'Inclusions' field lists all items that are included in the sale price of the property, such as specific machinery or fixtures. 'Exclusions' lists any items the seller will be keeping and are not part of the sale.
Do I have to display my property's address on the internet?
No, you have control over this. On page 9, you can select 'Yes' or 'No' for the 'Display Address on Internet' option to protect your privacy if desired.
What is the difference between 'Remarks for Clients' and 'Realtor Only Remarks'?
'Remarks for Clients' is information that will be visible to the public on consumer-facing websites. 'Realtor Only Remarks' contains confidential notes intended only for other real estate professionals, such as specific offer instructions.
