So your 90 year old grandpa has been living in a two bedroom apartment on the lower east side for 65 years. When he moved in at age 25, it was considered a crummy but affordable neighborhood, but now it's expensive and desirable. You want a 90 year old to have to move? I agree that maybe a 65 year old couple no longer needs to be in a 3,000 square foot home, but there are a lot of cases that make this complicated.
