Shared expenses in musharaka

Assalamu Alaikum,

I have noticed for most Islamic mortgage companies in the West, including those with top scholars on their board, that the diminishing musharaka program does not involve any shared expenses (insurance, taxes, utilities, etc). Is there a difference of opinion on this issue?

JazakAllah khair

@Mufti_Faraz_Adam @Mufti_Billal any insights here? I’m thinking this must be a common fatwa being followed given how widespread this practice is
