Damaged Vinyl Floor
The previous owners tried to repair their floor using the self-stick vinyl squares sold at the home improvement places. You can tell from the duct tape it didn’t work to well. In my experience, the self-stick ties don’t stick! They might have a chance if the surface you are sticking them to is absolutely clean, dry, and smooth. That is usually not the case.
That said, most homeowners can’t handle sheet vinyl, so what choice do they have? A few years ago the answer was “Very little”. Now days I think the answer is laminate flooring. Laminate flooring looks great! It is not hard to install. You can see how it turned out in this house by clicking on that link.
