They said they do criminal record background checks, income verification, evictions and collection accounts.

It amazes me how naive people can be to think that criminals wouldn't take advantage of this practice.

Hello My BP Family,    I'm going to be closing on my first out of area rental property soon, and was wondering what YOU use and believe is the BEST tenant screening service that preforms reference calls, credit checks, criminal background, and job verification.

I am looking for reliable contractors that do not have a criminal record. 

We do a criminal background, credit check, and call past landlords.  

5) I would like to run Criminal and other backgrounds on potential tenants.

I still run credit check, criminal check and eviction history. 

For a lender, that means 22 different laws and regulations at the federal level alone.That does not mean doing what you propose is impossible - it just means you have to be willing to invest time, effort, and money in getting your operation right or face the fact you are engaged in a criminal activity.The other question you asked about parks not working with you.
