These reasons only show me that you are completely stuck in your plan and see only an additional hallway as an alternative to another plan. That is of course complete nonsense.
Apart from that: If you have to sell your house, every cent counts. Let’s just hope it doesn’t come to that.
Who says that a hallway was ever the only alternative?
We have a 60% financing for everything (land, civil engineering, ancillary construction costs, house, landscaping work, etc.). If we ever can't pay the installments anymore, the bank will definitely get its money and whether we then have more or less left over doesn’t matter to me at all... but probably nobody here can imagine that either. I have already lived on so little in my life and that was not the worst time.
Maybe it’s not me who is completely stuck.
I just don’t know if this won’t be too exhausting for me in the long run. We’ll see.
