What Should I Do About These Floors?

[Kenneth Peagler]

So I just acquired another property in an amazing area for a low price with a high value. I'll be turning this into a rental property but I like to have an idea of how to handle a particular issue before I have professionals come in - or attempt to do it myself.

This house has old floors and in some places, it's uneven or a different pattern. I tore up the old, outdated carpeting. I know this is a DIY forum but I'm curious to hear a DIY perspective so that I have an idea of perspective.

Based on the photos: 1) Should I have the floors refinished, replaced, or cover it up with a luxury vinyl (which I've used in my other rental properties.) 2) What should I have done about places where the flooring is uneven. Any assistance would be appreciated.
