So we had our hearing before a judge yesterday and this morning and I'm very happy to report we won on everything! We've been granted possession. Tenant has 2 business days to vacate. The sheriff has already been contacted and is ready to remove her after the 2 business days expire, if needed. The lis pendens was declared spurious and invalid and has been removed. We were awarded legal fees for the lis pendens portion of the case. We will be discussing the possibility of suing for damages and loss of rent with our attorney next week. The question there is, if we were awarded a judgement would she have the means to pay it. My guess is, probably not. I'll keep this thread posted with updates and developments.
We've contacted our architect and contractor who will get to work next week, which I'm really excited about.
Lesson learned! In the future we will be sure that the tenants are gone before we close. The whole experience was a bit stressful but, call me crazy, it was a great learning experience and at times actually very interesting to see how everything worked inside the courtroom. I will say that having a really good lawyer made the whole experience a lot easier than it may have been otherwise.
Thanks to everyone who shared encouragement, insight, and advice.
