thoughts on taking out of Roth 401K for first time home purchase?

[Sondra Foley]

I have been thinking a lot about purchasing my first property, but I am low on liquid funds. I have considered taking out of my roth 401k because I believe there is no penalty for doing so for a first time home purchase. I plan on purchasing the property as an investment, either a rehab or rental and I figure I will make back the funds I take out so it can't be a bad option. Thoughts on this? Also,  what other feedback/options do you propose for purchasing properties without liquid funds?
