I promise you it will cost you far more to put the first person who passes the fog and mirror test in your home to avoid a vacancy, than it would ever cost if you set reasonable rental criteria and screen to that criteria.FYI that in 2020 the VA cap is going away!  

They are also well qualified by all normal screening measures. 

I do a standard screening process.

You can make money by investing in any part of town (distressed neighborhoods have renters too) but you need to know how to thoroughly screen tenants.

In the tools section click on landlord resources and download the ultimate tenant screening guide.

Some people have directed me to Cozy, so overall which site is best for rent collection and also background screening ?

I do enough tenant screening and applications (and application fees) that it balances out for me, but I wouldn't recommend it if you don't do at least 2-3 applications per month. 

Does Texas law allow screening multiple tenants and select the best one?

Do you have systems in place for marketing, screening and placing tenants, collecting rent, dealing with tenants who don't pay, and turnover?

Good renters may not be easy to come by. sometimes as cashflow is the best interest, but a good screening and understanding of house rules and regulations should be discussed in detail.
