My question involves landlord-tenant law in the State of: Pennsylvania

We have a rental. The tenent is always, every month late with the rent. He pays half on the first and half on/about the fifteenth. The whole amount is due on the first.

Now, since he went on vacation this summer, he has fallen even further behind - the half we get on the first is actually the second half from the previous month, and the half on the fifteenth is the rent that was due on the first, etc. This tenent cannot manage his money, if he has a dime, he spends a quarter type. He will never get caught up.

This is a month to month rental agreement.

Can we take his back rent out of his security deposit to get him caught up?

We are a little hesitant about eviction, this guy is a former coworker of my husbands and they are taking good care of the property.

I really appreciate any advice!
