Texas property code requires the owner or PM to make repairs that "materially affect the health and safety of the tenant" in a reasonable time (usually 7 days). 

It covers more in-depth topics like 1031 exchanges, real estate professional status, Opportunity Zone investing, investing with retirement accounts, etc.Hope this helps!

As for the unpermitted master bedroom, one of the ADU/JADU regulations states that only codes related to health and safety can be mandated when converting it to a ADU.  

You need drill down on city, neighborhood and street and get an intimate understanding of what types of properties are selling and where, how many are on the market and how many are under contract and how long for each of the statuses.

In addition, if you have an application to your property, and one application is from a family, the other from unrelated roommates, I assume preferring to rent to the family would be a violation of FHA's familial status, yes?

Like who’s president, economy’s health, stocks, local trends, etc.

You can also check with the attorney holding the auction and ask the status and what to do next.It is unlikely you will get the property at this stage.

My husband’s grandfather is looking to move closer to family due to health issues and asked if he could move into the side that currently has the tenant. 

@Shayleen Minott,Part of the equation here is the status of the tenant. 

Wait until you get a 3rd party report on his financial & criminal status.
