AITA for kicking my brother and his fiancee out after she used "my kitchen"?

I'm a 28 year woman who recently inherited a house from my grandmother. It's a big house so my parents told me that I could live there starting in June on the condition that I get the house in order, get it ready to be sold, and that I find a place to put my grandmothers stuff. I've been staying there since the middle of May, and have been consistently working on the house.<br><br>My brother and his fiancee are both in their early 30s and are getting married in the middle of July. They are currently living in a one bedroom apartment and they told me that they don't have enough space to store anything for the wedding at their place. I told them that they could store stuff in the garage if they helped me get my stuff out of there (my grandmother had an hoarding problem) and they could also store things in the extra bedrooms if they helped me get them cleaned and furnished.<br><br>They did a little bit of work, but mostly they have been focusing on their wedding plans. I have been doing a lot in those rooms, and I fully plan on completing them. I often work until 10 or 11 at night and my brother and his fiancee often get here around 7 or 8. They often go to bed at the same time I do. Almost every night they have made themselves something to eat and then left it for me to clean up.<br><br>This week they started moving things in the house. My brother moved his tools into the basement, and his fiancee had her best friend move the majority of her belongings into the extra room. I was very upset and told them that they couldn't move things in until the house was sold, and they needed to get out. She started crying and saying that she had nowhere else to put her stuff and that she didn't want it in the garage. I lost it and yelled at her and told her that she couldn't treat this house like it was her home, that the garage was the best I could offer, but that she needed to get her shit out of my kitchen. She then went on a rant about how I was such a bitch and that I didn't even cook and I was making her and my brother move for no reason.<br><br>I feel like I was completely in the right, but my parents are really mad at me over the whole thing. I think part of the problem is that I am the youngest and my parents always thought I would be the one to get married young and live in the family home. When I moved out my parents had some issues with letting go. I think that my brother and his fiancee are taking advantage of my parents sentiments and using them to guilt me into letting them move in. I also think that they think I am stupid because I'm the baby.<br><br>I just want to know if I was in the right here. Am I really being that big of an ass? I am so angry right now and I feel like my side of the story isn't really getting heard.<br><br>Edit: Thank you everyone for your support, it really means a lot to me. My grandmas house is my home and I feel so bad that I let things go that far. I know that I am the victim of a scam, but at the same time I am feeling a little guilty that I let things get to this point. I got off the phone with the police and they are going to try to get in contact with them shortly. I'll send an update with any info I get.<br><br>Edit: I have sent a location to the police and they are going to try to get in contact with my brother when they are out on patrol. I was able to get a key back yesterday, but I can't be positive that it's the only key. This problem might not be resolved right now, but I'm going to keep working on it.
