Just a reminder on the house sale - it was transferred to LV (by way of the Will, which had to happen before LV could sell it) and sold to the buyer on the same day.
If the offer to buy was conditional, those conditions had to be satisfied and signed off on before the agreed closing date. If an unconditional offer was made - even better. All that had to happen was the transfer made to LV. Seems there was a coordinated effort there - not a big deal - LV would most certainly want to unload this responsibility.
A death certificate would have been issued in short order - faster than the house transfer - and given to the next of kin or appointed executor in order to deal with financial affairs etc. That death certificate would give all access to all known accounts, investments, insurance etc etc etc - the person would not be expected to deal blindly with only what was current. LE would need a court order to freeze anything - maybe they did and left $50K to deal with the estate. But, if any outstanding loans could be established there was every reason to list that in the probate docs.
