Being from the Chicagoland area all my life, I can tell you that the neighborhood where the home is located isn't the greatest and those people are overshooting the mark here with their $500K fundraising goal. I doubt the project will move forward and I don't believe in the $500K will be raised either. Way too much money and they don't need that much to fix the house up. I understand making a healthy profit, but do it with your own money and don't rely on the goodwill of strangers on the fond memories of Walt Disney, to bank roll your scheme.
I get the strong feeling those people are are thinking Walt's former home is going to be the money making cash cow, like the Ohio "Christmas Story house" which was restored a few years back and seems to be very popular.
