NEVER loan money to friends/relatives. They will hold a grudge against YOU for the rest of your life if you do and EVEN if A) They Repay you B) They Never repay you. Makes zero difference. It’s best to NOT loan the money and keep the friendship.
What many experts recommend is to give them the money as a gift.
BTW, is this another can’t meet mortgage payments/reduced hours at work story? Tell them it’s tied up and you don’t want a penalty.
