I see what you are saying. You sound totally logical on these kinds of issues. I just want you to be really really careful so that you do not come across as pressuring, controling, or manipulating to your husband because then the crazy cycle would start all over again. So tread lightly!
I think that you could stay in the house under the preference of "budget issues" but if it did go badly then you would be under more stress because you would have to fight this battle all over again once your friend comes home and you have to find a new place to live.
