You can set the expectations up front, that's helped me a lot with finding, screening, and getting the best fit for the house with other like-minded individuals that respect the house and each other.Also, another insurance policy is to give every roommate-tenant a 2-4 month lease to start as sort of a trial period to see how they fit in with the house, and if they aren't a fit, you can choose to not renew them and then replace them with someone that is a fit.

A little trial and error, and you should be alright.

The tax treatments in TX are likely favorable to you as investor, particularly because there's no state income tax, but there are likely other loopholes you can take advantage of with proper planning, so DIY on entity formation and tax structuring could be an expensive trial and error lesson. 

Many offer a free trial so you can just try it out and see. 

Everyone goes through the trial and error of their first deal at some point.

If you do decide to use a Listing Service, try them out on a trial basis.

These trials ultimately provided me with invaluable hands-on experience and inspired me to develop my own systems and methods for conducting business more effectively.

My company pays for DotLoop so I use that the most and my Realtor dues pay for Transaction Desk with Authentisign, which has a free 30-day trial.  

Regardless know that this area is trial by fire for a newbie from out of town. 

As a new landlord, you'll certainly learn the business, likely trial by fire, as we did.
