Add A Line Of Custom Text Underneath Price

Some of the products on my website have an option to rent, and we’d like to be able to show the rental price underneath the buy price so it will show up something like this.

Product Name
$1,000
Rent Me for $50/week!

I’ve looked in to it, and it seems very difficult despite being something so simple.

Does anyone have a solution to this?
