Loan types for first rental property

[Michael Klaus]

My wife and I are interested in purchasing our first rental property and are looking for ways to finance. We have a decent amount of capital saved but don't want to sink 20% down on a property. We purchased our first owner occupied home at 5% down this past April where we currently live. I understand that type of financing may not be available for rental properties, correct? However, I have heard about portfolio loans but admit my knowledge on the matter stops at the name. Thanks in advance!
