We do have a brand new (few years old)  low income apt complex in the area that rents a 3/2 for $700, but I'm assuming I'd exclude that from the comparable properties for rental prices, since mine are single family homes (I know I exclude then for sales price, so I would assume also exclude them for comparing rents). 

I can leave them if youd like but I will not repair them when they fail and they are specifically excluded from the lease."

I had not considered that it might be illegal to exclude or require a particular type of payment. 

On top of the forms used there is an unlimited amount of items that can be included/excluded from them.

They have absolutely no right to exclude you from your property.

Places are only improved when a tenant moves out(excluding repairs of course).

., You can use smartmove as an initial screening process, but if it is based solely on credit history, you will be excluding certain groups like young people and the elderly, who may make excellent tenants but do not have much of a credit history.

@Curtis Bidwell  As I understand it in MA, the owner occupant CAN exclude families from children, at the time of initial rental, BUT agents are not allowed to screen out those families, they must present all qualified applicants to the landlord who then has the right to exclude them, AND (another big) BUT, once those tenants are in place, the landlord has no ability to control their family size (ie pregnancy, adoption, custody changes, etc).

@Mychal Raynes, my insurance company is Allstate and according to my agent their policy does not exclude any particular breed.

Landscapers and attorneys are other employment types that people exclude.
