Moving on Mom's house

[Fred Martino]

Ok we are finally making some progress on Mom's house in Scottsdale.  My two sisters and I inherited equal share of my mother home upon her death in 2010. My sister who lives in AZ has decided to buy us out. The house just appraised for 603K.  My question is should this considered a Cash sale or not?  Since she is keeping the house and has had the benefit of using it for her adult children to live in for the last 10 years (rent FREE).  She is proposing this breakdown.

appraised value $603,000 x 70% =$422,100-$43,100 (repairs)=$379,000-$44,000 (our costs)=$348,000 / 3 = $116,000
her previous expenses for repairs, taxes and such were about $25k over the past 10 years which we agreed to split this 3 ways.  But I am not sure where the $43,100 comes from or for that matter the 44K for (our cost) if this closing cost should be more like 9k on a cash sale right, with no points or realtor commissions. Seems like my sister and I are getting taken here.  Any thoughts are greatly appreciated. Thank you
