I am curious if I am understanding the only way a tenant in Texas has a right to withhold rent is if there is an amicable agreement between tenant and landlord or if the landlord fails to remedy a problem with the house that impacts the the safety and health of the tenants.I am trying to keep things simple and not complicated on this question. :)

Most cities would likely be best off with limited restrictions (limiting enforcement time & costs) other than enforcing any already existing health and safety laws.

However, after researching it and having her actually do her homework it came to light that divorce, separation, health issues, moving for a job, and a few other extenuating circumstances were the only exemptions for no paying capital gains before 2 years of having it as a primary residence. 

If somebody put paper towel or feminine products down there, I would hold them responsible.The next question is whether or not the tenant was obligated to notify you in a timely manner that 1) the toilet was continuously flushing and/or 2) that it was leaking after it clogged.For #2, it sounds like they notified you soon after they noticed.

The current owner has owned for 30 yrs and needs to sell for health reasons. 

Whether it’s the economy going sour, or you are growing old, or bad health, you must have a “backup plan”.Many of us hate to talk about having our burial planned out or having life insurance, but it’s something we need to talk about with our families and plan for, and so most of us do.

Obviously, living without electricity may be hazardous to both the tenant and the property.To that end, I would NOT contact any mental health services.

Otherwise, it is mighty dangerous, because everyone wants to be in expert in health, law and taxes, based on their extensive Facebook studies.Your friend has (correctly) heard that the new tax law allows Section 179 for rental properties.

I'm a doctor so these conversations come naturally to me, it's just that your diagnosing the home owners needs and wants rather than the patients health. 

People who have been driven from their homes need things like dry goods, baby formula, water, diapers (for children and adults), toiletries, feminine products, blankets and jackets (cold weather is upon us), undergarments, shoes, gift cards for goods and groceries etc.The thing most people don't realize is that those who have lost their homes are looking at 2-3 years before they can rebuild, assuming they had adequate insurance to even rebuild at all.
