Conventional financing for -- Commercial (residential multi units)

[Francis A.]

Hi -

I'm wondering if anyone has any info (recent or otherwise) to expound upon with regards to financing on 5+ residential units. 

IE: 

- How commercial financing differs from conventional (duplex, Triplex, 4 plex)

- What are the various downpayment stipulations, percentages [down], combination [if applicable] etc.

-  Is there a version of the "owner occupied" in the commercial space and if so what does it  (or do they entail) etc?

- Do different interest rates apply to commercial (5 units+ residential) and non commercial (duplex, Triplex, 4 plex)?

- Any other "off the beaten path" nuances THAT DO NOT OCCUR IN NON COMMERCIAL that are unique to commercial that one needs to be aware of etc etc.

- Anything else that would be helpful...

Thanks so very much!!!
