Multi family seller financing

[Dave B.]

Hoping I could get some quick help. I'm newer to REI and currently invested in SFR's as I've purchased 5 homes worth an avg. of 160k over the last two and a half years. A family friend brought a deal to me for a small 20 unit apartment building and I've started to play with the #'s, ran it through the deal calculator etc. Can someone shed some light on how most people traditionally structure seller financing deals for multi family? Having only purchased SFR's through a conventional mortgage I'm a little confused on the most common ways to structure commercial deals, especially those including seller financing. What are the typical downpayment terms, # of years, interest % etc? Any help is greatly appreciated! DB
