Competition across the street does have rents at our potential estimated rents but a few more amenities are offered such as pool, pets, vending machines, etc. 

If her home is close to the retirement home, perhaps people could stop by the vacant house on their way to visit grandma or stay there if they live out of town and are visiting grandma.I'd also disconnect the washing machine.
