I put true in bold because many times tenants believe any request is an emergency to them, so its important to set limits and HIGH fees for abuse.

Typically when you clean a carpet you are cleaning the surface of the fiber, and if the carpet is maintained properly this is sufficient, How ever a abused carpet will have soils, oils, urine ect. absorbed into the fiber, into the backing, into the padding and even into the subfloor. 

Believe me I bet you could google them and deny them based on the weed smoking posts.

They need to have a notice of whether their application has been accepted or rejected, and if rejected, why, and if due to credit, a notice about being denied due to credit, from what credit agency you got the report, etc.  

But we also got a tenant application who I have to deny. 

To get to that point for the hearing it may cost up to $25k in consultant fees and it may be denied.

First, while you should have homeowner's insurance and umbrella insurance, these policies have gaps and claims can and sometimes are denied.

I've yet to see a credit union that will deny the use of one of their credit cards due a member purchasing an item the credit union disagrees with.

The deal should also work on its own, even if you get denied on your proposed project.

You cannot deny the family because of the lead paint either, that's considered discrimination (you're refusing them because they have a kid) and is against the anti-discrimination laws of the state.
