AITA for telling my sister she is being spoiled brat and obviously mom isn’t giving her a house no matter how much work she put into it.

My sister is pissed at me so I figured I should come here for some opinions.  Also we can’t afford this house, it is probably over half a million

My mom owns a house that she got went her own parents passed aways. She got the house in 2019 and she hates this house. Covid happened so selling the house got put on hold and she had to pay everything on it.

She was going to sell it in 2022 but my sister needed a place to stay. She just got out of a divorce, no degree and needed help. So my mom allowed her to live there while she went back to school. My sister is now graduated and has a stable job as a nurse. The whole time my mom was paying for the house. My sister didn’t pay rent.

My mom doesn’t visit the house, she hates it. She has made it so clear she is excited to sell it for years. My sister has been renovating the house, I thought mom knew about this but she didn’t apparently.

Anyways to the main issue. Mom is selling the house and she told my sister she needs to be out by Christmas. My sister didn’t take it well. She came ranting to me about the situation and said she deserved the house since sheput so much work into it.

I snorted and she asked what the fuck that was and I told her she was being a spoiled brat. She got free housing for 4 years and mom made it so clear she was going to sell it. We got into an argument and she is pissed I sided with mom.

I said it was fucking stupid for her to even think she was going to get a free house. Thats not how it works.
