If an inventory item is labeled as a custom ordered item the customer is required to pay a 75% deposit. What would be the proper way to check all line items to see if this custitem87 = CUSTOM so that the deposit information is displayed on the Estimate PDF? Currently, it is showing for all estimates using the following sytnax:

${(record.total*0.75)?string.currency}

This is located outside of the existing item list body tables so I am unsure of what would be the best way to check all line items for this field. Thanks.

I think you are probably trying to solve this in pdf when it's probably easier to solve in custom fields on transaction

To do this within the template, you can do something like this (untested code)

<#assign hasCustomOrderedItem = false>

<#list record.item as item>
  <#if item.custitem87 == "CUSTOM">
    <#assign hasCustomOrderedItem = true>
  </#if>
</#list> 

<#iif hasCustomOrderedItem>
  This order contains a custom ordered item and a deposit of ${(record.total*0.75)?string.currency} is required.
</#if>

Thanks @michoel . This worked like a charm. After passing custitem87 to a Transaction Line Field I was able to successfully perform the check and switch on/off the deposit info accordingly.
