The sheriff then came with 2 inmates to clean up and remove the body.

Doesn't the city permit office make sure the property is repaired correctly...to code...apart from the smell?

A simple measure to keep drains clear and smelling fresh is to put 1/2 cup of baking soda down the drain, followed by a cup of vinegar poured slowly.

During our initial walk-thru the house, it had a HORRIBLE smell in the kitchen, an equally horrible smell in the family room (pet urine), and we found that the kitchen drawers and cabinets were infested with bugs - we had no idea what they were. 

It doesn't pass the "smell" test.

Purchase price was great, the smell was not!

The description of the property condition you've given coupled with decades of ownership smells like potential neglect to me. 

It does not say anything that I am suppose to provide a form then again I don't know if Texas code picks anything up and mandates that a landlord is required to provide a form.I am making a form up now for my property the tenant is suppose to move in actually two months after commencement technically the property was considered good to go five days after the initial contract signing then there was an issue with the house regarding water coming into rooms and mold that was obvious and smelled in another portion of the house.I spoke with the tenant they are cool with me providing a form at a later date projected to be November 1st, 2018

Sometimes legislative bodies will write an initial draft of a bill with super harsh restrictions and then lessen the restrictions in response to public backlash and in an effort to pass a bill.

If they smoke enough of it inside the home will still smell when they leave, which will cost time/money on the turnover.
