Yes, it takes the money away for the value of the home. And since it will be created without a sim on the lot, it won't have depreciated value, it will be full value of the house build and furnishings.
We're living outside now, even though I had the landgraabs move in, but that's not really fun.
If not, it's fine, I'll just have to take a few days to build the house in the dynasty save, I just won't get to play. (It really does take me a bit to build a house... and not even a good house. haha) I just figured it was my creation, and it will not lose any value as it's not being built by a sim, it'll be just a regular build, so I will have to pay full price for the build. But I'd rather be on the safe side and know before I even do it, cause I do not want to have to restart again (though I fear that will happen at some point).
