The tenant has expressed multiple times the desire to change things (paint) but never actually did so I am taking this with a grain of salt and told her we would discuss again when she is ready to move forward.Whenever that tenant moves out, I would probably have to replace the current carpet due to age and mini blinds are also old (but functional), which is why I am considering the idea.In any case, I would be reviewing quotes, finances and contractor and figure out a way to make sure the work will be finished before I OK the change.

So I would still remove any carpet in bathrooms but only deep clean dirty carpet (if possible) and just make sure the kitchen baths are functional.
