Thoughts and Idea!! Buying Grandma's House!

I know buying a home could be a good thing but also bad as the housing market is dropping daily.  Last month alone my grandma's home dropped !

Zestimate	$134,600	$89K – $198K	-$3,100		02/29/2012

However a loss isn't my fear and the profit is not either.  My goal is to see the house stay in the family.  I do not want the 7 Family members to regret selling it for $135-145 for the small $20k each.  Either way they see it as a hassle and profit.  Greed, what else has america came too?  What has america taught you?
