We live in the state of Minnesota, and at the time our renters moved in we collected a deposit in the amount of $900. They later wanted to get a dog, so we collected an amount of $500 for a pet deposit. The renters turned off the heat this winter and all the pipes froze. Those damages along with some unleft cleaning total nearly $3000.

Can the $500 pet deposit be used towards the amount of damages even if the damages weren't caused by the dog? Also, if the renters do not pay the remainder of the bill, what is the best way to go about collecting this money?

Thanks!

First, if the receipt for the pet deposit was clearly labeled as pet deposit you cannot apply it towards damages. However, if you sue them for the damages and win a judgement, you can then withhold it. So I would immediately take them to small claims court and obtain your judgement, before you are required by law to return the pet deposit. This should still leave a balance owed. You can try to go after their checking acount or garnish their wages aa long as you have a judgement.
