Hard money interest after closing as a seller

General question for the HMLs and those that use them out there. When selling a property on which you have a hard money loan, how many days of interest is it typical to pay to said HML after closing? Meaning I am aware there can be a delay between when the title company handles everything and when the wire is received. An associate was recently told they were responsible for a week's worth of interest after closing, but was not told whether or not a portion would be refunded if the funds were received sooner. I am just curious what is typical if anyone has any insight?
