I moved from a house with nearly the same square footage. But, I went from a 3-story plus full basement home to a single-level home; with an attic which I purposefully left inaccessible!
That factor was paramount in my thinking, and has proven to be worth every penny! Being challenged with emphysema, the stairs really got to me. Now, since there are none, I can, theorhetically, run everywhere!
