Home Equity Financing vs. 401K down - 2nd property/investment

[Jack Taylor]

I'm trying to put together some financing to buying a multi-unit rental property, which may or may not become my primary residence. I'm short on the cash side, so it looks like I may need to pull equity out of my condo (primary residence) to pay for the down payment or use 401K to pay for the down payment. I'm a little skeptical about both. Any thoughts on either of these options?
