How do you access the most recent item in a custom object?

We use custom objects to store data pertaining to our customers' homes.

Since a customer could own more than one home, the result is multiple items (or homes) in the "propertyDetails" custom object.

Whenever I use scripted email tokens to populate an email with this data, it uses the oldest item.

Here's the Velocity script that Marketo uses by default:

${propertyDetails_cList.get(0).streetAddress}

Can this script be changed to reference the most recent item's Street Address?

Thanks in advance!
