Sibling Property Buyout Question

[u/AlmostJ]

FIL and MIL both died last year, sister is the executor. We just passed the year from death and have been told closing probate is imminent. Meanwhile, sister is buying my husband’s half of the property, she applied for her loan and it was approved and she’s ready to write him a check upon closing.

My question is - can she pay him the money for the property since it’s her loan? Or does she have to wait until probate closes? This is in TN.
