Best way to finance a 5-unit property

[Dino Lontoc]

Hello Tampa BPs

I found this property with 4 separate units of 1/1,  1  2/1 and two vacant  multi-family/commercial lots. The numbers look good and I would like to purchase it.  This will be my first multi- family purchase so I don't know the best way to finance it.  

Here's my situation: I have 5 investment properties that are paid off.  (I practice BRP:  buy, rent, pay off;  not proud of it but that's how I want to invest).  I have only $ 40,000 for down payment.  The property I would like to purchase is $850,000.00.  My properties are valued at 1.4 M.

Can someone point me in the right direction please?
