how to passively track apt building rates

[Paul M.]

Is there a way to passively track mortgage rates on 5+ residential apartment buildings?   They are generally not published or advertised, or at least not where I know where to look.  I can check in with my local bank, but I don't want to waste their time when I'm not yet serious about doing a loan with them.   Since these loans usually have interest rates that reset at 5, 7, 10 years do they behave like regular residential ARMs?
