It is suggested that  "Small" landlords use a collection agency, who will report the non-paying tenants to the credit bureaus.   

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

Marcus,If you want more exposure you can list it on the MLS, and you will have to pay a fee to the agent that brings you the tenant then you will have to do a credit check and background check yourself for each applicant however for my clients I prefer to list it on Zillow rentals only, because I can manage the applications directly from there and the prospective tenant only pays $35 application fee once and can apply for different properties with the same application fee.

If they pay everything cash why do they have a low credit score?

So your going to pay me with my money????

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

The college girls are very sweet. 2 play sports on scholarship and work and have told me they pay their own way with their scholarship money, loans, work etc and have good references from previous landlord and credit score. 

To pay for the renovation, we did a cash out refinance.

Paying too much from the outset.
