Tenant wants to pay more than agreed

[Maria G.]

I have a rental property with a year lease. When tenant deposited the first payment they pay more than agreed because they are very happy with the unit. Should I do a new lease or an amendment whith the new amount? Thanks.

What?

That is obviously not very common.  Are you sure the tenant didn't misunderstand the amount due on the lease?

As it stands right now you would owe the tenant a refund for the amount over the amount due on the signed lease.  I don't think you can retro a previously made payment since that contract is signed already.  To be clear, you need to refund the overage.  

If they want to move forward at a higher payment you would need a new agreement.
