The police report will also have their names and ID so you can use the information for the eviction.It is essential you have a police report to substantiate your position that they are trespassers.The court requires (since there is a conflicting claim regarding the right to possess the premises) that it be resolved LEGALLY.

But how does this compare to "Note Brokering" - or clearly the practice of connecting a note seller to a note buyer and collecting a commission.With that said, does note brokering pose a legal issue as well if you're not in possession of a RE license?

Actually, in Texas it is five days for them to appeal, before you can file a writ of possession.  

Check state laws as to collections.Obviously the optionee is not a successful attorney, probably a loser with a degree, so I'd go full bore from all directions, beginning with an eviction for possession and fight the option another time, these are two different matters.

To me it looks like @Frank Jiang was shown their filled out form while they were perspective tenants and then he approved them seeing that they had no pets. then when they moved in and he got the official copy of their lease they did, in fact, have a pet. 1. if you do not allow pets let your property manager know immediately and try to stop this before they move in. 2. if they have moved in and taken possession of the property then you might be stuck with them3. either your PM made a huge mistake or he hosed you and maybe he knows these people. no matter the situation though I would definitely call your property manager ASAP and try and straighten this out.

I ended up doing what @Daniel Mohnkern suggested - did move-in inspection on the day of possession and used it for the move-out. 

here it generally takes 60-90 days after the auction to get possession of the property.  

The exposure to doing this immediately is if sale were to be reversed or former owner claims possession had not been fully surrendered.Therefore, I would take pictures of interior being vacant as well as utility meters that are shut off, as applicable.

@Sandy SpenceWhen you get possession of the property and have it all cleaned up, make sure you shoot a video.
