Replacing Carpet Flooring

[Caleb Henry]

As stated before, I currently living in a condo that I own but need to replace the carpets throughout the whole house before I turn it into a rental property. My wife and I are planning on getting a free installation from lowes because they have that deal but I wanted advice before we move forward. It's approximately 1150 sqft of flooring that will be replaced, we were thinking about switching the main hallway and living room to something else like engineered hard wood or vinyl or something but really arent sure what's best for renting or if we should just keep it all as carpet. And then the other question would be should we just get low grade carpet (I.E. like 1.25-2.00$) or mid grade? (3.00-5.00$) Thank you for any advice!
