Another washer dryer question

[Marci Stein]

My (excellent ) tenant moved in 8 years ago, has never been late with the rent.

The rental came with a washer dryer in the basement and I told her they are a courtesy -  I would not replace them if they broke and now they have. 

 when she moves out, would it be best to, ask her to replace them with another pair of used machines that work or just take the loss. They were old but functional. thanks for all thoughts.
