Adopted tenant lease question

[Dylan Meeker]

I recently purchased my first income property.  The property is a duplex and the bottom unit came with inherited tenants. The lease doesn't specify whether the washer/dryer is the tenant or landords responsibility. This is my second month as their landlord they've been late both months and actually still owe me for this month. I didn't really intend on supplying washers/dryers to tenants and it seems every time I have contact with these particular tenants they have a new problem or excuse why they can't pay. Back to the topic, my question is, since it's not specifically mentioned in the lease do I need to fix or replace the washer that they've complained doesn't work?
