Buy (1) multi-unit for cash, or 2-3 with a mortgage?

[Mike Malone]

My partner and I have 200k cash on hand to buy a multi-unit. We've bought and sold 3 single family homes and 1 two flat over the last 5 years but would like to be more aggressive with our next move. 

Located in the Midwest - our basic question is, should we buy a 4-unit building for 200K cash, or should we focus on mortgages for 2 or more similar properties and pay all the interest on the loans?

We are looking to hold for 5 years and then reassess. Rent is roughly $600 per door.

If you are wanting to be "more aggressive" then use as much debt as you can, and buy as many as you can.  But leverage increases risk, but will let you buy more property, more quickly, which sounds like that is your goal.
