Chadnliz, I went through the house search process recently and I commiserate with you on the challenges of finding the right combination of house and listening room. FWIW, my belief has always been to try to go larger than 21 feet if possible, and avoid substantially square rooms. The difference in support for the bottom end in a larger is pretty significant. You can drive yourself nuts over finding the right room with the "just-the-right" dimension ratios. But, you can overcome some imperfect ratios if you have enough volume to begin with. You can't make the room larger.
I'm a soundstaging nut, and I love a system setup that can both maintain accurate timbre and recreate a believable acoustic space. I find the best mix of factors for doing this usually involves being able to get the speakers (dynamic drivers) well out in front of the wall behind them 4-6 feet or so) and decently out from the side walls. I also find it very satisfying to work with a space where my listening seat is 6-10' from the wall behind my head. (Of course all this changes depending on room dimensions.)
Good luck!
