u know u could always refuse to let anyone in the house and change the locks, i had a landlord who wanted to kick me out, but i wouldnt let him in the house altho i was eventually evicted... i was doing it for laffs
i did manage to live there for 3 months rent free and no bills, eventually the police kicked the front door in and i was arrested.... nothing new there lol. but seriously, get some peace of mind about ppl mooching around ur house at anytime, change those locks and get ur home back to urself, make sure ur landlord *has* to notify u exactly when ppl are going to come round, and u are there to let them in, cos in the uk, a landlord has no right to enter a rented property without prior notification, i dont know if tha applies to u where u are, but i would try and enforce that anyway, and ur landlord is trying to do a major dump on u, i would stall and stall until ur landlord gives way to u, and gives u the chance to find somewhere else

might all sound a bit harsh but i think he needs to be taught a lesson inb this case cos he is not allowed under UK law to treat u like this

love eezer
