I live with my mom and she and I will be moving soon and buying a new house. My mom was going to gift me the house and live there with me so I wouldn’t have to worry about not having anywhere to live when she eventually passes away. (Hopefully not for some time. She’s only 75). She was thinking of leaving it to me in the will, but I’m afraid one of my two sisters will fight it and I will again be out on the street. I’ve read though that there are gift taxes up to 40% on anything over 14,000. I’ve also read that you can gift a house without paying gift tax as long as the house isn’t more than 5.4 million (and it will be nowhere near that amount). I’m not sure which one is true on property. If she will have to pay a large gift tax I will pay it, but I’m wondering if there’s another way around that. I’m also wondering if she gifts me the house if my sister will be able to fight that when my mom eventually passes away. My other alternative is perhaps getting a mortgage once I’m working again (I've been out a few years due to illness and pain) and just buying it from her. Any help would be appreciated. We are in Illinois.
