401k borrow or withdrawal/ cash-out?

[Julie Dillon]

My husband and I are 51 and 52 and only recently got into real estate investing so we want to be aggressive in growing our doors. We have 2 single family homes and 1 duplex and now we are pursuing a 4-plex. We cant decide whether to borrow or simply cash-out my husbands Fidelity account. The account is relatively small so there is no way to retire off the current balance. I'd love to hear what other people have done in this situation and the pros and cons of each option. Thanks!
