I have a question about parents funds . They have about half a million in property ( rental , home ownership ). With numerous varying savings and investments . Currently they are caring an $90k mortgage on their living residents . Renal property is paid in full, They are in their late 60’s. My question is this , should they pay off that mortgage and free up money or sit on it , btw its in the stock markets ( scary times ) . Their plan is to leave all property to me and my siblings .
