# Files, messages and questions

Find files and messages, and ask questions about operating cost statements.

The bottom of a statement's detail view may contain messages from your landlord or property manager and additional files.

## Message to tenants

If the landlord has added a personal message, it appears under **Message to tenants**. It may contain explanations, notes about the statement or information about the next steps.

## Files

The **Files** section contains attachments, such as supporting documents, separate calculations or additional explanations. Open the documents in the portal and save copies for your records if needed.

{% hint style="info" %}
The landlord or property manager provides these files. If a document is missing, contact them directly.
{% endhint %}

## Record of viewing a statement

When you open a provided statement, Immodio may record that it was viewed in your account. This lets your landlord or property manager see whether the digital statement has been opened.

{% hint style="info" %}
This record shows only that the statement was viewed in the portal. Ask your landlord, property manager or an appropriate adviser about legal delivery requirements and deadlines.
{% endhint %}

## Ask a question about the statement

Contact your landlord or property manager about amounts, cost items, payment methods or refunds. If they use Immodio messaging, open **Messages**. Include the address, unit and statement year so they can identify the statement.
