Like do they have pets, how many occupants will there be, etc.

The lease (and property information that we've got up to this point) states that they are paying $670 a month, but when we look at the lease and pet addendum, they should be paying $670 a month + $25 per month pet fee.

19.Do I have to allow pets?

If you do not have resident alien status or already file a return in the US or own a domestic US tax paying entity then you will be subject to FIRPTA withholding on every sale. 

I love the smell of pet urine in a house for sale. 

Thanks in advanced :)Leeron,In LA, you cannot evict a tenant unless they have broken the lease (by not paying rent, by having pets that aren't allowed, by being a nuisance, etc).It doesn't matter whether the tenants are Section 8 or not.Best!

Neighbor has complained multiple times of possible domestic abuse screaming and yelling.

Also property management has told me it smelled like dog urine in the backyard where pavers are and we didn't allow pets when as part of the contract. 

I do non refundable pet fees versus refundable pet deposits.

Make a list of questions that you deem appropriate; when do they need, how many persons to occupy, what is their budget, any pets, have they ever been evicted, have they or are they currently in bankruptcy?
