Owner financing an 11 property sale, can I get a bank loan for the down payment?

[Jennifer Jesse]

So, my husband and I are newbies and still trying to learn all we can. 

We have met and built a relationship with a fella who is looking to retire and wants to sell his 11 SFH rental portfolio.

We are very interested, and have about 45K for a down payment, but he's wanting 150K down, and he'd finance the rest since he owns these free and clear. 

My question is can I get a loan from the bank for the remaining 105K, and what positions would everyone's notes be in. 

Sorry I'm still trying to wrap my head around all this financing/bank/mortgages stuff. Some of it is clicking though. 

PS he is willing to sell us 2 or 3 of the homes with our down payment, but gosh they are all wonderful prop in great areas and were greedy and want all of them!
