Should I use a 401K loan as a down payment for a rental property?

[Monica Young]

My husband and I are thinking of using a 401K loan as a down payment on our first multi-family rental property. We may or may not live in it as well. We both work full time and we'd like to use all of the cashflow to pay back the loan & then after that, save for another property. If we live in the property and the other unit covers most or all of the mortgage we can pay down the loan faster. Does that sound like a good strategy?
