AITA for suggesting my brother's family not live in our house after my parents die?

My brother and I grew up in a very large house that my parent's company built. I live several states away from my family now, but my brother still lives close. He spends a lot of time there and his kids practically live there on the weekends and during summer vacation. His kids know the house inside and out and know all the tricky little things about the house like which cabinets you have to actually pull hard because the magnets are stronger or which lights are touchy because they require a specific type of bulb. I've only been back home a handful of times since I left.<br><br>The house is quite large, and my parents have a whole in-law suite for themselves. Basically it's a 2 bedroom house with a kitchen and living room that is separate from the rest of the house. My brother has told me multiple times that he and his family plan on moving in when my parent's die, because he wouldn't want to part with the house. <br><br>Like I said, my parent's company built the house, and it is their "showcase" house. My dad was the president and my mom was the vice president. He has since retired and she has passed away. My dad has always assumed that he would leave the house to our family when he passes, but the board of directors has recently expressed that they would like to have the house for the new president to live in, and for my dad to sign some sort of paperwork making it company property. My dad has said hell to the chief because his idea was to just give it to us, but let it be used for company parties when needed. He said he would absolutely never sign anything to make it official company property. <br><br>My brother called me up yesterday to ask if I had heard about the company trying to take the house. He told me he didn't think my dad would actually let them take the house from us, and that he couldn't imagine the house being with anyone but him. I told him that the house is not his. I suggested that he purchase his own home instead of relying on the inheritance of the house. That's when he flipped and said that the house was his home, and this was just further proof that I was an asshole for not caring about my family.<br><br>AITA for not wanting to give my brother the house that he has been relying on getting?
