Iif you are starting out and have little to no funds, I'd go with borrowing as much as you can for as long as you can.If you are an intermediate investor has good cash flow generating, you may want to mix it up with some 30 yr amorts, and some 15 yr amorts.If you are a seasoned investor, maybe not acquiring as many new properties, looking to ratchet down a little, then maybe go all 15s.

Is any seasoning required?

remind them who they work for - I been down this route many years ago - now as a seasoned investor - learn what to tell them - to get what you want - in the beginning, I took many names - and wrote many letters to their superiors - not trying to be a jerk!!  

Do any of you more seasoned investors that live in the area have any advice for me with getting started?

I have a seasoned investor that has one signed with me to help him find a property he is seeking.
