Yes, I think so, but only because "as good as you can afford" usually means to people "as much money as the bank will loan me" instead of "as much as I have carefully budgeted."

I bought as much as I could afford, but my budget included savings and a cushion. The bank would have loaned me plenty more than what my budget could afford. And my budget included repairs and maintenance. I also included in my budget a 4 bedroom house costs more than a 900 sqft town house to heat and cool. The big thing was I wasn't willing to give up maxing out our retirement accounts.
