I have heard great things about modern wood floor options, especially the pre-finished boards that friction fit together & left floating on the subfloor. I was assuming that IowaMan's home would be similar to mine, since he said he grew up in it, & the floors would likely be the old 1950s-60s grade materials. But since you bring it up, his best bet (if he can handle the expense) may well be to lay down new floors that don't require the sanding or finishing, thus avoiding the dust & fumes factor altogether. Myself, I couldn't bear the thought of covering up those old floors, installed by the last true craftsmen & intended to outlast the homeowners.
