Seller Financing a 12 Unit

[Keagan W Poole]

After asking 50+ investors in my area, one finally agreed to seller financing

Here it is:

12 Unit Complex in a good size city (population 65,000+). I'm only interested in long term multi-family rentals.

Owner said he would offer seller financing for those (2) properties (12 units total) for $250k with a good down payment. 

Taking into consideration that my credit is shot with under $500 in the bank, how could I go about help funding this. I was thinking a partnership, but unsure of where to look. I understand I'm young and may not be able to operate 12 units, but I'm willing to look into as many options as possible to make it work. Any help is appreciated!
