Midwife visit?

My midwife was talking to me about having a visit to be able to see where the baby will sleep the Moses basket etc as I’m 21 weeks. However I still live with my parents at the moment and I’m still trying to find a place to stay it’s very stressful. My parents don’t really want them coming round as they’ve argued that the baby wouldn’t be sleeping in the house anyway and there’re scared about the fact that our living room has has been halfed with a wall for a extra bedroom that they didn’t ask for planning permission for and on top of that I currently don’t have a bedroom because of overcrowding so I sleep in the living room. This all isn’t ideal and im working on it the baby wasn’t planned but could they do anything because of this? Could I just cancel the visit or would they have a problem with this?
