Hi Tawana,
We currently use Yardi, but pricing might be a bit much for smaller organization. However, I have a good friend out of Maryland, who has approx. 5,000 units under management, and they use Boston Post and love it! I did a demo run, and it seemed to be very user friendly. Not as detail as Yardi or Onesite, but will get the job done. Looks it has been disigned specifically for Affordable Housing deals, but workable for Coventional Market Rates.
Hope this helps!
Sincerely,
Pedro
