When to make repairs or replace damaged items?

[Jason Smith]

I have a single family home that has been leased to the same tenant for 3 years.  They pay on time but are extremely messy people.  There are 4 broken or missing window blinds, a broken kitchen drawer, molding damaged by the cat, etc.....   Should I go ahead with some of the repairs and charge them for it?  I know I can keep the deposit but I'm concerned the deposit may not cover all the unseen things that might show up whenever they move.  I know I will have to repaint the inside of the house too.
