My name is Jamaal Jaynes, I'm 21 years old and Senior Criminal Justice major at East Carolina University in North Carolina (Go Pirates!).  

Nice that we all have to worry about becoming criminals over the victimless crime of seller financing....

If they do not have criminal records

Beyond that, my one page application and I don't use credit scores but I do check for criminal and eviction records, which are dis-qualifiers.

Beenverified lists phone numbers, relatives and associates, criminal record, liens and judgments and more. 

I do like the idea of making it look not vacant to criminals though.Ok say that you, don't post the address ever, and only give out lock box code to trusted individuals that you may have worked with before. 

Or something resulting from criminal activity?

—In all criminal cases, contempt cases, and other cases filed pursuant to this chapter, if a party has sold, leased, or let real estate, the title to which was not in the party when it was offered for sale, lease, or letting, or such party has maintained an office bearing signs that real estate is for sale, lease, or rental thereat, or has advertised real estate for sale, lease, or rental, generally, or describing property, the title to which was not in such party at the time, it shall be a presumption that such party was acting or attempting to act as a real estate broker, and the burden of proof shall be upon him or her to show that he or she was not acting or attempting to act as a broker or sales associate.

Criminally so.

Being unlicensed means if the real estate commission finds out, they have no authority to discipline and must file criminal charges.
