Spent a while digging and found out some clarifying information.
As we know, the homeowners for the s1 house are Zi Qian and Jun Zhang, who are father and son. Not sure the extent of which these two have been discussed in the community, but these guys are rich as fuck and do fucked up shit because they can. They were both named in a lawsuit, Fun City Trampoline Park LLC v. 1275 Fall River Ave LLC et al. In short, they're getting heat for pretty much taking a trampoline park business right out from under tenants of their property and making it their own. Alongside that, it appears Jun Zhang has other ongoing civil cases regarding unpaid wages, labor laws, etc. He does have a criminal record as well. There's even a reddit snark page for the daughter/sister of the two, Mei. This family is facing a ton of heat in the courts already, and when the police came to the s1 home the last time, some 33 year old from Cedar Rapids was given a summons arrest for breaking and entering and assault. I don't know if this was mentioned anywhere either, but it's all public record if you look up the house address. That being said, with what happened at the house regarding the B&E charge along with the permit issues on the wigger side and the behaviors/ pre-existing legal issues of the homeowners, it's fair to assume Zhang(s) probably told them they had to go because they couldn't handle another legal matter and especially couldn't handle being associated with the wigger crew any longer as it would make them look that much worse in the public eye.
As for the second house, it would be safe to assume that the governments of these places are working alongside each other (due to the shitstorm they faced/are facing, such as the Town Hall meeting that already exacerbated concerns about the show and endless complaints from residents) to try and put a stop to the show considering how quickly they got kicked out. The people in charge probably got wind of them going back to that house in one way or another and began preparing to get it shut down before they even began streaming there this season.
