If they do let them stay for a couple of extra days, do not simply take the current rent and divide by 31, do that and double it.

I am just exiting the last of my Cleveland stuff and its very evident there as well Just like James Wise said you have a certain price point and area of town and no matter what you do or who you have its a savage business the tenants simply do not live their lives like the landlord does. 

If you want to save some money you can simply look up the owner name on the county website.

Unless there were holes in the walls or something that looked obviously damaged by them, I could see the wear and tear defense being accurate.

Lots of students want good, cheap housing and won’t shy away from holes in the wall or other cosmetic issues, and will rent by the bedroom.

Can the issue be avoided if I simply wait to sell until I leave Japan?   

But the damage caused by hanging them (namely puddying the holes and touch up paint, or repainting walls if touching up doesn't work) will come out of their deposit. 

We simply would change the lease dates to be 1 month to make it a "MTM" lease.

For example, a broken fridge door, broken window, holes in walls…Normally I would repair it but what if it’s becoming a constant thing?
