For help with the section-8 process, it's very important to have a PM that's familiar and connected with the HUD programs in the selected market. 

I've used other programs in the past (Quickbooks) and an old fashioned spreadsheet, but neither worked for me.

They are not even programmed to do far simpler sniffing tasks than this, and a year-to-year comparison is extremely hard to automate, both technically and logically.Who does it, then?
