Uneven flooring options

[Andrew Caldieraro]

Hello,

I’m looking at a 1350 sqft 3B, 2B house that is over 100 years old for a rental property. It will rent for ~$1000/month. It doesn’t need much work, aside from flooring replaced. It currently has linoleum flooring in the kitchen and bathrooms,and carpet everywhere else. The flooring is quite uneven. Some areas slope a bit, other areas under the carpet you can feel significant variations in the subfloor (it feels like some variations are close to 1/3 of an inch). While it’d be impossible for anyone to give an estimate to fix this without seeing it, what options do I generally have?
