Thanks for your response, BG. Totally understand that you’ve been busy.
BTW, not sure why you’re calculating different housing/mortgage types, as that has nothing to do with the expenses incurred when the second income earner chooses to work outside the home. We can assume that they are living with parents, or living in an apartment, or living in a SFH that they had bought when prices were more reasonable, or in a condo, or in a mobile home. We’re assuming that this couple is already living somewhere when they are trying to run the numbers and make this decision.
Assume that all else is equal; just factor in the taxes and extra costs of working outside of the home.
We’re trying to see how much that second income earner is *really* netting (positive or negative), all else being equal, if s/he chooses to work outside of the home. Please refer to my original post to see what we’re trying to discover.
