What is the lowest down payment option for an investment property?

For your standard conforming conventional loans (Fannie / Freddie), it depends on what the property is. A single family home can be as little as 15% down, but you get better rates with 20%, and 25%. Multi-family homes (up to 4 units) will require 25% down.

Ideally, you want to put 25% down.. But like Joe said, 15% down for a single family residence.. duplex, 4plex, condo, etc.. will be higher.. Also, with 15% down, you will be paying mortgage insurance.. I'm a Broker here in Scottsdale AZ and I only lend in Arizona.
