If you are a DIYer, I'd say go for it!
I just did my own floors and sold my live and flip in January. I had a pretty tough predicament, a layer of vinyl flooring was glued onto the original floors with mastic. If you do have the black gooey tar mastic you need a diamond blade that spins to scrape it off. Make sure to rent the right equipment for your task. Make sure to take the time to prep the area, remove shoe molding etc prior sanding. It's worth it.
The difficult part isn't the broad sanding but the corners and edges near the basement. Be prepared to be on your knees for extended period of time. Knee pads and respirators are essential. Also dust gets everywhere so whatever means to contain it in the room you are sanding would be great. Ventilate out. ALSO, you may want to prioritize sanding prior to painting the walls since the fine dust can really dull the walls. It won't be perfect but embrace the "handcrafted" imperfection of your floors. I actually dislike the newer "perfectly uniform floors. Original hardwood floors over modern plastic looking wood floors anyday. Also spend time deciding on what finish you'll be using. Water based vs Oil based. But this is a topic for another discussion.
