Input: My mother recently passed away and didn't really have much of a will other than for my two brothers and I to split things evenly and not fight. She had a retirement fund that after splitting, before taxes, each of us will get around $53k. Two years ago her house appraised for $65k and my brothers thought there was at least $22k left on the mortgage it and had no interest in moving in or buying the property so it was verbally agreed I would buy and live in the house from the estate. We recently found out that there was only $12k left on the house so now my brothers want me to give each of them $5k from my portion to make up the difference. I know I am getting a really good deal on a house but we live in one of the poorest counties in Illinois where one out of every five houses is for sale and is on the market for an average of three years. So it's not like I'm flipping this property and pulling a fast one on my brothers, in fact, I'm going to need to do foundation work, put on a new roof, install new windows, and do several other pricey renovations to the property.  
So am I the asshole for being reluctant to pay my brothers extra money because a previously thought property price was incorrect?
