@Loren Clive I agree wholeheartedly with your opinion to do both. I also max my 401k and even contribute taxed monies after the yearly max has been reached. I just started with REI however and my first deal will close this coming Thursday. I plan to continue purchasing RE in the buy/hold strategy with as many deals as I can generate. My hope is to have at least 10 paid off in the next 12 years. Getting back to the subject at hand, 401ks are a great tool for many reasons with company match being the first (provided you receive one). I have used the 401loan twice for investing purposes only. First, to buy stocks in a personal brokerage account and most recently for the down payment on my first REI. The money I pay back goes to myself so its a win,win,win. Also, by making taxed contributions, I'll have a little nest egg later that will not be taxed when withdrawn. I love the the thought of earning a small fortune through passive income generating REIs, but I think it's a great idea to throw your eggs in as many baskets as possible. For me it's stocks, mutual funds, ETFs and finally REIs.
