No good landlord will accept 13 animals in a rental.

It's not normal to do it prior to an accepted offer.

Everyone knows who the new person is and the goal is always to mess with them and test them and try to get them to spend their money on the junk so we can get the good ones. 

An experienced agent will list your property with the language, "no showings until an accepted offer", to avoid violating your tenant's rights to the peaceful enjoyment of their home - possibly resulting in their lack of cooperations and a lawsuit against you.

Quote from @Joseph Bushnell: I'm testing out the idea of building a data center and I was wondering if anybody has heard of owning the building and having a third party operate the data center itself.  

There are tests you can buy on Amazon, where you can swipe it on the walls to determine residue.

Early testing of this new system indicates that it’s a pain to get access to.

Now, with taxes, insurance, and interest higher and rents not keeping up with property values, most investors are putting more down to get the properties above a 1.0X DSCR. 80% is acceptable, but the issue is getting the property to cash flow at the higher amount. 

I've seen a lot of your posts and I'd be interested to know what you think differentiates those 'few' investors that do manage to scale their businesses from the 'most investors' that are unable to achieve a gross ROI that would generate acceptable profits for a sponsor and investors?
