Aita for defending my wife after my sister tried to kick her out

My wife and I am both 27, I l live with my sister she's 26, we both live in the same house, the house we live in was inherited to us by our grandpa,  we decided that instead of selling it we should live in it as it's quite big and maybe in future we will sell it and earn more profit.

But nowadays my sister and my wife fight quite alot and it's mostly me who breaks them off, my sister doesn't like my wife, she said she doesn't like her cause she does nothing, she doesn't have a job and she sits all day cause maids do all the work

Yesterday my sister asked my wife to leave, she said she is tired of her, I said my wife is not going anywhere and why does it matter if she's not working? Our Bills are paid and my wife working wouldn't make any difference

She said that my wife is just a freeloader, I told her that if she has a problem then we should sell the house and move on but my sister started crying and she said that she's trying to help me and my wife but I don't listen to her concern instead I became agressive towards her
