My answer to the original poster, put a tracer on the money order, and they will reimburse you for it.  

If you seek reimbursement beyond this, you will have to look to your renter's insurance policy.Sincerely,YouSomething like this, is what I'd do. 

In our lease it states "...reimburse Landlord, on demand by Landlord, for the cost of any repairs to the premises damaged by Tenant or Tenant's guests or business invitees through misuse or neglect..."

Splitting the cost can be tricky unless it is made clear in writing they do not have any rights to the item or reimbursement when they move out.

If they provide a receipt you will get a quote from your ac tech and reimburse this for that amount.  

., and that we strongly suggest they get renter's insurance to cover them, tenants will look at you in shock and amazement that they have to pay for their hotel bill, beyond the reimbursement for just the rent amount (which of course doesn't touch the hotel bill).  

I have asked you verbally to reimburse me the rent for 15 days that you have received double rent on - from me and your new renter.  

Landlord will reimburse Tenant an amount equal to $38.33 per day for each day ($1150/30 days) that the apartment is unavailable starting on May 1 st .

When this happens, I told them that I keep the original security deposit until all original tenants are gone, and they'll have to figure out between them, who reimburses who what as far as the deposit goes.  

No need to reimburse the credit check.
