Hi, apologies for the slow response.
So my situation resolved itself in time. The tenant/ did not damage the property beyond a couple of items of standard wear & tear. However, they did not leave on their own. I had to pay a county constable fee and hire movers to remove their items from the property. We did not have to store the items, just set them on the curb. All in the whole process including filing fees, constable fees and mover fees cost about $1,200. We managed to save on attorney fees as my dad did a bunch of research online and appeared in court himself.
Few things I learned.
1. Tenant screening, tenant screening, tenant screening! Although in this case these were inherited tenants from the prior owner. I don't think he screened them since he was selling.
2. Evictions in Texas, while stressful, are relatively fast and cheap compared to many other states. The whole eviction process took approximately a month and could have been quicker had we knew what to do.
With that said there's no way to speed up the state mandated waiting periods for each stage. This means you need to be prepared and somewhat familiar with the eviction process before the need arises. Be sure to post the proper notices on the first day you are allowed. We were tempted to give them a couple of extra days to make the payment and not post the eviction notice. Instead of doing that I think it's better to post notices and then explain that the whole process stops once the past due amount is paid.
Lastly, I'm not too sure on differences between counties. My guess would be there are no differences, as county law is determined at the state level. There would more likely be differences at the city level. I.E. Dallas vs Ft Worth.
