How to tell my homophobic family they can never visit my apartment/house because I live with my fiance?

I am 26 years old and I’m about to graduate from graduate school. My soon-to-be husband and I are planning on getting an apartment together in a new city. It will be a two bedroom, but one room will be an office space. The other bedroom will of course be our bedroom. We are immigrants from a conservative culture.

My parents know that I am moving to this new apartment. It is only about one hour away from their house. My mom knows that I have a boyfriend, but when I came out to her, she told me that I was a disgrace and that she would kill herself if I ever told anyone else about my sexuality. She has not brought up my relationship or my fiance in anyway since I came out to her about three years ago. I don’t know if she actually knows that I am going to move with my fiancé soon. She does know that I live with him currently, but I think is willfully pretending that I am breaking up with him and moving an hour away or something lol.

My issue is that is is only my mom who knows. I don’t know how to tell my family that they can never visit me, and that they will never be able to see my apartment. We are also currently saving up for a house which we plan to buy within a year or two. It would be within the same area because that is where my job is located. I wouldn’t know how to tell them that they can also never visit my new house. I am close with my family, so hiding these things from them is extremely painful. They also have my location, so they would know that I am living in a house at that time, and they would know where my apartment is. Of course, they can visit me in my new city, but I would always have to tell them that they cannot stay with me. I would actually have to tell them that they can’t even come inside the apartment, because it’s going to be obvious that I co-inhabit with my fiancé. I could say he’s a roommate but it’ll be kind of obvious that we’re sleeping in the same room etc.

I am looking for excuses to tell them for when I say that they cannot come inside my apartment, that they cannot come inside my house, And that they can never stay with me in a guest bedroom.
