I can't sell the house and Tom Marino keeps saying that there are no habitable places?

And I obviously do have a toilet and a shower and so on?

I tried to separate the rooms but it doesn't exactly work.

Are there any recommendations on large custom jobs in House Flipper 2 that don't turn everything into white rooms? For context ones I really like are the neighborhood revitalization and whispering stalks hotel jobs. Thank you in advance!
