Could my tenant win in court for claiming that my rental is uninhabitable and get an extention?
Your tenant is bad news and is just using the “uninhabitable” thing as an excuse. It sounds like she isn’t going to be able to provide any proof that she notified you about any wiring or plumbing issues, so she won’t prevail. Also, the key to a place being uninhabitable is that the person can’t go on living there, which she did. From what you say she had a history of nonpayment and general bad behavior before she came up with this latest excuse. I still think you should get some legal advice, though, just to get all your ducks in a row.
