Another factor might be the short length of her retirement.
I don't know whether I get the timeline right, but I guess she retired around the time she hired Emma and she employed her for approximately 5 years before she died.
But she also did not leave much inheritance in the story: The house was rented, Emma got a dress, and there didn't seem to be other heirs.
Maybe a former employer let her live in the house or paid for her retirement. It's probably cheaper to offer such a contract and "bet" on an early death, instead of paying her enough to cover the "risk" of her living until age 100. Also, if your income is from land ownership, small, regular payments over a long time are easier to do than higher payments over a shorter period.
