Financing 85% purchase price 26 Unit Apt Complex 100% occupied

[Cody Dover]

Came across some gold a realtor sent me, seeking advice on how to creatively finance 85% of the purchase price of a 26 unit apt complex. My partner and I can scrape up the other 15% or $110k. How would one go about presenting the other $550k to an investor who has the funds. The annual gross rents pull in around $94k per year after expenses. How could we structure something that will be long term and not quick turn around?

A.) Give them a certain rate of return percentage so much a month but them be out longer on the note

B.) Or pull out equity after 1-2 years and give it back in a lump sum?
