I always said this as my elderly parents did the same with an investment property, they kept the rent low so that it wouldn't affect their pensionMakes sense why she was allowed to live there when rentals are going through the roof. Old person not wanting to fix anything or family of old person not wanting to fix as the plan has always been to sell. She got to stay just to provide maybe a bit of income without the loss of pension benefits that a sale would probs have caused.
