Raising Money for a 36 unit

[Alex Jamael]

Currently have 8 units over two buildings and looking at a bigger acquisition. I found a great 36 unit complex spread over 3 buildings, great shape. Ideal price to acquire would be 1.7m, net profit of $156,000 per year. I am looking at raising money for the 20% down payment, I have been thinking of either doing a 8-10% roi for investors OR offering an equity Stake in the property. 

Questions:
If you do an equity stake; does it get complicated with having separate owners , having to draft legal docs etc? 

The 8-10% Investment option have many people had good luck with this and particularly anyone raising 100% of the money? 20% down payment private lending and 80% bank ?

sorry it’s a long one appreciate anyone’s opinion!
