Carpets are the worst. My wife had a company that fixed tenanted apartment units for landlords.
Trying to get the landlord to pay was nigh impossible, for anything. That’s why the carpeting and flooring company left, when they saw ruts, they were probably breaking even as it was. And ruts wasn’t previously mentioned, or in the budget.
Glad you’re able to move and buy. I’m sorry this happened to you when you were already dealing with health issues.
