How should I finance a 10 rental property purchase deal.

[Anne Laurenzi]

A friend of mine has a landlord that is wanting to retire and move away from the area. He owns 10 different rental properties and wants to sell them eventually. I haven't talked to the man or even looked at the properties yet but it's in the works. My question(s) are;

How would I go about financing 10 properties at once? Obviously a normal mortgage for all 10 won't work. 

Is my best option to find a bank that does portfolio lending? How likely are they going to loan to someone without other investments or collateral. I don't have any other properties yet, just my personal home. I have a good paying job, a good credit score, and a modest bit of savings. 

Is there a creative way to come up with the down payment(s) or a way to purchase without down payments?

Thanks in advance, 

Mike
