Jolene,
I strongly believe that having a separate set of eyes review each files aside from your onsite staff is important. Onsite staff gets sometimes to comfortable with the day-to-day operations and can easily overlook or make a simple mistake that can cause the ownership their credits. At my company I have a Affordable Housing Specialist and a Compliance Auditor. They review all move-ins, recert and programs reports before execution. Before I had my own staff, I used third-party companies such as Spectrum, FileCap and Preferred Compliance. I actually was the founder and partner of FileCap, which is now own by Apogee New Dawn. However, I'm not sure if they are still accepting outside clients, or simply servicing their own sites.
Hope this helps.
Thanks,
Pedro
