Where did you get this not very specific information from?
Just a little research. Tracked down her address and looked on Google Earth to see what the actual lot size and roof appearance of the house is. She lives on a court with houses of varying sizes and hers is nothing large or fancy. I have no idea what the actual sales value of her house would be. That area, near White Plains, used to be working class but has been gentrified lately so that the houses her court backs up to are large.
