Here's the gist of it:

I live in a house behind another house occupied by these insane kids that like to party and scream at all hours of the night. It settled down 4 months ago after my going over there three times to discuss the noise (they apologized then promptly ignored me and continued being loud anyway), at least 6 calls to the cops (4 of which I made) who apparently only noted one incident and my calling the landlord who threatened to throw them out should they not settle down. Everything was paradise until 2 days ago when I started hearing their wild parties/screams (once around 7pm, 9pm and 2am).

I called the landlord who dropped the bomb on me that he lost the house and it's in foreclosure and he has no legal recourse as to kicking them out. Apparently they are living there rent free and with no landlord and no fear of the police.

Everyone I've talked to has told me to call the police but after having 4 conversations with 4 different cops each of which who told me that should this happen again, the next time they will get arrested for disturbing the peace -- I think they are useless (...don't even get me started on how ineffectual the cops are here...)

What I need to know is: What can I do to get them thrown out?

Note: I live in orange county, florida (orlando)
