Hard Wood Floors?

College Student Rental!!!!

 ok I have Hardwood Floors in 75 % of 1st  floor and 90% on second floor(rug glued down over it).. 1st floor hasn't been maintained at all but there's no buckles and it really just looks old and worn. 2nd floor -I ripped up a piece of carpet and it's all wood. Couple of questions: I realize if they put down carpet could be because the wood is in bad shape but if not I would prefer to have it all wood.( the carpet has to be replaced regardless ) It's 4 bedrooms. Approx 750 sq ft with hallway- down stairs is probably 750 as well -  would you go with resand/poly floors upstairs or rug?

And any clue as to what it would be to sand/poly both floors?

Some tell me 1.50-4.50sq ft

I've never done but would love to give it a go- rehabbed a couple of basements over the years so I am fairly handy. Could I do it myself?

Thanks
