If that is true I think you're on the right track. 

Quote from @Malcolm Brown: My real estate agent provides listings (multi family homes).

Any time you are looking for updates to your build, we have a dedicated email for you to send requests to – we ask for 72 hours to respond because we have many builds, clients, permits, jobs, etc. that we are tracking and working with on a daily basis– and of course we value every relationship.

Can keep track of different tenants.

Quote from @Tristan Kelly: Investment Info:Small multi-family (2-4 units) buy & hold investment.

I am actively looking to connect with investors interested in [mention specific types of investment opportunities,  single-family homes, multi-unit properties, distressed to expand my portfolio and deliver strong returns.

A multi-unit property was purchased for $140k. 

Airy closer to Germantown Ave, the more north the better (19119)Garden Court (19143), Cedar Park (19143), Walnut Hill (19139)B: New construction going on but mainly as multis, few SF build and sell, most action are in flips rehabs, no bars or restaurants yet.

We recently helped a client with a large $20M+ cash out refi on a multi use property in Delray Beach.

That's actually the property ID, it works similarly to an MLS ID but is specific to Redfin to keep track of the properties uniquely.
