@Mark Frattini the fact that they brought the dog in without permission is a lease violation and I would request formally that the dog be removed or they move out.

Did you remove any walls on the kitchen/dining room/living room level to get to that layout?

If you ask the manager to justify a fee and he starts hemming and hawing, move on or require them to remove the fee.

Drywall, ventilation system, appliances are all removed and disposed of in a special way. 

Do I pay the sheriff to go and remove them ?

the police might be able to get them out if they are really squatting but you will probably have to go to court to have them removed

These are porous and take stains which are almost impossible to remove. 

I am the seller and the buy has not removed his contingencies by the specified date.

My Insurance policy for the property was recently cancelled because of 'dangerous animal' on property.I already made the Tenant signed a new lease after 30 days that prohibits Pets butTenant refused to remove the animal because Tenant claims she had it before I bought the property and also because the dangerous animal is 'sentimental' to her family.

With homes and apartments being removed via Brownsfield grants to the city people have to live somewhere.
