@Patrick Britton & @Joe Impagliazzo Thanks for the replies, our issue is that we have 0 credit.

By carefully vetting potential tenants, you can mitigate the risk of late payments, property damage, and other issues that can arise from irresponsible renters.

@Wes Glass nothing you can do unless pet causes issues for other tenants.

@Jay Hinrichs  I think part of the issue is that while we might consider it entertainment, so many people see these podcasts, etc as fact. 

It's pointless and only causes issues.

We actually have the option to STR on a few of our properties and decline to do so because we make more money than an LTR on our medium-term rental with a lot less work than an STR.The pros to medium-term rentals: high occupancy rate, no local regulation issues if you are 30+ days, elevated rents, more and more people are staying longer, often the midterm rental tenant pool is professional. 

Here's a good site that lists out operating costs (Link).

The major issue is that the some windows are moldy and some have rotted frames.

Can you link me to that blog post you mentioned?

It just becomes a marketing and pricing issue.
