Pre finished hardwood floors

we have one prefinished hardwood floor in my parents house. we have finished it more than once, maybe two or three times, but i don't think that we can do it again.

i hear that some with the factory finish last a long time. the house we are buying has them downstairs, but they are brand new so i could tell you more in a few years...and that doesn't really help.

maybe you could ask around in home depot and lowes.

we did the pre-finished.
We bougth it at Lowes, and the pre-fin was more expensive than the un-finished.
BUT-
Here are our reasonings on why we did the pre-finished:
Though it's more expensive, you save $$ in the long run. To install the pre-fin, you only need to hire someone to install it. (I DO NOT recommend doing it yourselves, it's back-breaking work)
With the unfinished you need to install it, sand it, a few coats of stain, a few coats of finish. You also need to rent the sander. That's more labor and more $$.
Also- since we gutted the house, I don't think I could stand any more DUST. No matter how hard I try, I can't contain it, and if they needed to sand our floors, the dust would make me FREAK.
And lastly- with the pre-finished, it was done QUICK and there was no waiting for drying etc.
That last one sold me!

Hope this helped!!

ETA- and as for refinishing, with the one we bought our installed told us we could refinish it as much as we want. It was really thick.
