In negotiations, I got the previous owners to fix the roof, hvac, and to add new carpeting.

I added free carpet cleaning every 3 months to my leases.

If the carpets gross replace it!

Rugs and/or carpeting upstairs help the problem.2.

Both bathrooms had stained blue carpeting in them.

That means professionally clean the carpets, bathroom and kitchen are cleaned and sanitized, and so on.

Ripped out carpet on first floor and installed LVP.

Notes: -Carpeting will be replaced with LVP throughout -Wood paneling will either be removed or painted over (filling in gaps, sanding, etc) -Considering closing off the sunken in space to make the wall flush?

Tore out the carpet in all the rooms and replace with click tile laminate flooring, this will be better in the long run.
